5. DESCRIPTION AND INTENDED USE

PETROJET Biorobot boilers are designed for heating water with forced circulation in central or

individual central heating systems with water gauge pressure up to 200 kPa and operating

temperature 90°C. The boilers are designed for burning pellets.

The main parts of the boilers consist of the boiler drum, PETROJET burner with a control unit. The

boiler drum is welded out of steel sheets and pipes, its inner area is divided into combustion

chamber and exchanger through which the flue gases flow to the exhaust gas orifice. The fuel is

burned using a burner located in the combustion chamber. The fuel is fed to the burner by the feed

screw from the fuel container. Through the rotary vane feeder the fuel gets to the internal fuel

feeder which moves the fuel to the combustion area of the rotary grate.

On the outside, the boiler drum is jacketed with removable covers with surface finish. The covers

are fitted with thermal insulation.

CAUTION – Before the boiler operator starts the burner it is necessary to read this

manual thoroughly.

6. USE OF THE BOILER, FUEL

Steel hot-water boilers Biorobot 15 and Biorobot 30 are a source of heat suitable for heating

apartments, family houses, commercial premises and similar environments with thermal loss 6–

30kW. The heating system must be equipped with a pressure expansion tank and forced

circulation of the heating water, with maximum gauge pressure 200 kPa.

The prescribed (certificate) fuel is wood pellets manufactured according to ÖNORM M7135

standard or DIN 51731 standard with diameter 6–8 mm, length 5–20 mm.

The tolerable fuel, provided that the burner is adjusted accordingly, is biomass pellets, paper

pellets and bark pellets with diameter 6–10 mm, length 5–20 mm with maximum humidity up to

15% and spalling up to 50%.

7. DESCRIPTION OF THE BOILER

The boiler is welded out of steel sheets. The inner space is divided into combustion chamber and

exchanger through which the flue gases flow to the exhaust gas orifice. The inlet and outlet of the

heating water is equipped with pipe couplings with inner 1 ½“ thread. The flue-gas ducting is in the

axis of the boiler on the back side.

The fuel is burned using a burner which is located in the combustion chamber and which is based

on the rotary grate principle – a patented system PETROJET. The fuel is fed from the feeder

hopper by a feed screw (motor with transmission, ribbon flight) to the burner. Here it is fed to the

rotary grate. In automatic operation the burner switches on and off according to the required

temperature of the heating water (which can be set by the boiler thermostat) or according to the

need of heat in a reference room (by an external controller – e.g., room thermostat). It is possible

to connect normal controls, e.g., equithermal control.

In case of specific requirements for spare parts, order it in agreement with the manufacturer.

When ordering please specify the type of boiler, size, serial number and year of manufacture.

Spare parts and accessories of boilers can be ordered directly from the manufacturer or retailer.

12. BOILER INSTALLATION

The boiler may be installed only by a specialized contractor.

In particular it is necessary to comply with the provisions of ČSN 06 1008 during the

installation and use of the boiler.

Boiler installation must conform to the applicable regulations, standards and operation

manual.

The vendor shall not be liable for damage caused by incorrect installation.

13. CHOOSING THE RIGHT BOILER SIZE

Choosing the right boiler size, i.e., its thermal output, is a very important requirement for

economical operation and correct function of the boiler. Boiler BIOROBOT 15 is designed for

buildings with thermal loss up to 15 kW; boiler BIOROBOT 30 is designed for buildings with

thermal loss up to 30 kW. By adjusting the burner you can reduce the power of the boiler

according to the requirements of the building up to the minimum power of the burner. Some

tolerable fuels may affect the level of minimum and maximum power of the boiler.

14. PLACEMENT OF THE BOILER

The boiler may be installed in the basic environment AA 5/AB 5 according to ČSNN 33-2000-

3:1995.

The shortest admissible distance of the outer contours of the boiler and flue gas ducting from

highly and medium-flammable materials (see the annex – Flammability of construction materials)

is 100 mm.

The shortest admissible distance of the outer contours of the boiler and flue gas ducting from low-

flammable materials is 200 mm.

The distance of 200 mm must also be complied with in a situation where the degree of

flammability of the material has not been established.

Safe distance must be also complied with when putting furnishings, kindling material and fuel in

the room where the boiler is installed.



The boiler must be placed on a non-flammable floor or non-flammable insulating mat overlapping

the top view of the boiler at least by 300 mm on the front side, on the other sides by 100 mm. for

easy operation we recommend installing the boiler on a non-flammable mat with size of 100 to 150

mm.

The boiler is to be connected to the power, 230V/50Hz, using a power cord with plug, so that the

plug is always at the operator’s reach. It is forbidden to tamper with the electrical installation of the

boiler.

CAUTION – The room where the boiler is installed must be provided with permanent

supply of air for the combustion. The amount of air needed depends on the power of the

boiler: 45–60 m3/hour (this corresponds with the air inlet opening with size 200–300 cm2).

15. CONNECTING THE BOILER TO THE HEATING SYSTEM

WARNING – PETROJET Biorobot boiler is designed for systems with forced circulation.

In order to reduce condensation of flue gases and also extend the life cycle of the boiler it

is necessary to equip the boiler with a system that ensures that the temperature of the

return water does not drop below 60 ºC (dew point of the flue gas). This can be achieved

e.g., by a three-way or, if applicable, four-way mixing valve or thermostatic valve (TSV).

Equipment of the boiler with a system that ensures that the temperature of the return

water does not drop below 60 ºC (dew point of the flue gas) is a condition for the

existence of the warranty provided to the consumer in the duration of 24 months.

The heat transfer fluid should be pure soft water – preferably filtered rainwater or other fluids

designed for that purpose. A fluid with low freezing point and anti-corrosion effects, FRITERM, can

be used as a passive protection of the boiler.

16. CONNECTING THE BOILER TO THE FLUE-GAS DUCTING

Attach a stove-pipe with a regulating damper to the exhaust orifice of the flue-gas ducting using a

rivet with diameter 5 mm; if necessary continue with the stove pipe to the chimney. Attach the

stove pipe to the damper pipe again using a rivet with diameter 5 mm.

The flue-gas ducting should be as short as possible, with gradient upwards from the boiler.

The flue-gas ducting, only fixed in the chimney flue and attached to the exhaust orifice of the

boiler, must be firmly assembled and attached to prevent incidental or spontaneous loosening; the

pipe exhaust should not be longer than 1.5 m, if possible without bends. All parts of the flue-gas

ducting must be made of nonflammable materials. For solid fuels the flue-gas ducts must consist

of pipes inserted into each other in the direction of the flue gas flow.



17. CONNECTING THE BOILER TO THE CHIMNEY

The boiler must be connected to the chimney flue in accordance with ČSN 73 4201 and with the

consent of a chimney-sweeping company.

The boiler in a central heating system must be connected to a separate flue. A chimney with the

correct draught is a prerequisite for proper function of the boiler. It affects the performance of the

boiler as well as its efficiency. The boiler may be connected only to a chimney flue with sufficient

draught. The most suitable chimneys are insulated and lined chimneys. The actual draught shall

be checked by measurements by the installation organization.

18. ASSEMBLING THE BOILER AND THE BURNER

BOILER STEERING SYSTEM

Boiler temperature is controlled by electronic unit, which is located on the boiler body. This unit

switches off or on the Burner. Control unit has safety thermostat which switch off the burner by

disconnection its power supply in emergency cases.

BURNER TO BOILER CONNECTION

SET-UP OF THE BOILER AND THE BURNER

1. Please check:

a) the inserted provided accessories – set of cleaning tools, i.e., rod, scraper, brush, inlet valve, exchanger cover ball, jointing material, installation and operation manual, warranty certificate.

b) the imbedded provided accessories – fuel feeder, connecting flexi hose, clips



2. Install the inlet valve.

3. Attach the holder (ball) to the exchanger cover.

4. Prior to the installation of the burner it is necessary to remove the top and side cover of the boiler and pull the control unit including cabling through the openings in these covers. After having pulled through the control unit re-attach the cover to the boiler and install the control unit to the holder.

5. Place the burner to the boiler and attach using 4 nuts M10 and 10.4mm washers, according to the figure.

6. Insert the feeder to the fuel container with the end where the screw of the feeder is visible, and attach the other end to the burner using the flexi hose. Do not forger to attach the supporting foot to the body of the fuel feeder.

19. SAFETY INSTRUCTIONS FOR THE BOILER OPERATION

The boiler may be operated only by adults demonstrably trained by an authorized technician (i.e.,

people listed and signed on the “Training and burn-in handover protocol”). The boiler operator

must follow the operation manual and may only switch the boiler on and off, set the temperature,

combustion mode on the burner control unit, and check its operation. It is strictly forbidden to

leave unattended children near a boiler which is in operation. Modifications of the boiler which

could endanger the operator’s or other people’s health are strictly forbidden.

The boiler may be operated at water temperature not exceeding 90 ºC and must be checked at

least once every 24 hours. It is forbidden to use flammable fluids for lighting or increase the output

of the boiler over the rating (overload) in any way during the operation. No flammable items shall

be placed or thrown to the vicinity of the stoke or ashtray hole. Ashes must be placed in

nonflammable containers with lid.

In a situation leading to the risk of temporary production of flammable gases or vapors during

works with a temporary risk of fire or explosion (e.g., gluing linoleum, PVC, etc.) the boiler must be

put out of operation in time before the occurrence of the risk.

20. BEDEWING OF THE BOILER

CAUTION – With the initial heating-up, water precipitates on the boiler walls and flows

down to the ashtray area. This bleeding of the boiler walls may give the impression

that the boiler is leaking. The bleeding will disappear after settling of the flue ashes on

the walls of the liner (which occurs approximately after two or three days of operation).

If condensate forms in the boiler also after the first days of operation this phenomenon is

undesirable and may cause damage to the boiler which is not covered by the warranty.

The most probable cause of bedewing:

Incorrectly functioning or nonexistent short loop

Too low temperature of flue gas

Wet fuel



21. SAFETY OF THE BOILER OPERATION

During the operation of the boiler it is necessary to comply with all applicable safety regulations, in

particular ČSN 06 1008 Fire safety of local appliances and heat sources.

PETROJET Biorobot boiler may not be used for any purpose other than as specified in this

manual.

The surface of the boiler may be cleaned only with ordinary nonflammable cleaning agents. No

items made of flammable materials may be placed on the appliance or within a distance which is

less than safe distance.

No flammable material (wood, paper, diesel fuel and other flammable materials) may be stored in

the room where the boiler is installed. The minimum permissible distance of the outer contours of

the boiler and flue gas exhaust from materials with high and medium degree of flammability (which

stop burning spontaneously after igniting without supply of additional heat energy – degree of

flammability B, C1, C2) shall be at least 100 mm.

The minimum distance from materials with low degree of flammability (after ignited they burn and

burn up – degree of flammability C3) shall be at least 200 mm. The distance of 200 mm must be

complied with also in a situation where the degree of flammability of the material has not been

established.. Removal of solid combustion residues from the ashtray area – The ash tray, located

in the middle of the ash tray area, is made for this purpose. The ash tray needs to be emptied on

regular basis before it is completely full. The handle on the front side is used for the removal and

handling of the ash tray. After having removed the drawer from the boiler empty the ashes into a

prepared container designed for ash removal. Use protective equipment – gloves during this work.

LIQUIDATION OF THE PACKAGING

Liquidate the packaging using a recycling yard or use a controlled dump site managed by the

relevant municipal authority.

LIQUIDATION OF THE PRODUCT AFTER THE END OF ITS USEFUL LIFE

The product (boiler) is to be disposed of using a recycling yard or use a controlled dump site

managed by the relevant municipal authority.

INSTRUCTIONS FOR ENSURING SAFE TRANSPORT

The boiler is delivered from the manufacturer’s warehouse in disassembled form on pallets. The

pallets may be handled using normal handling equipment (forklift, pallet truck). During transport on

vehicles the load must be secured against moving and tipping.

22. BOILER FIRING

Check before firing:

o Water volume and pressure in heating system



o The tightness of the heat exchanger cover

o Fitting of the cleaning door

23. OPERATION INFORMATION

JAMMING OF THE FEED SCREW

The feed screw may be jammed by a hard object in the fuel (for example a larger stone or metal

screw). The operator must ensure that no such objects are present in the fuel.

OPENING THE BOILER DOOR

Opening the central door and looking at the flame is only allowed for a period of time necessary to

adjust the burner. The door may be opened only by trained operating staff. Open the door carefully

because there is a risk of flame flashing out. Use suitable protective equipment.

You may prevent flashing out by first opening the door only slightly for a few seconds before

opening it completely. It is necessary, however, to realize that particularly in high outputs the flame

may flash out of the door. Open the door only wearing gloves. When removing the ash tray drawer

with ashes always use protective gloves, and place the ashes in a nonflammable container which

can be closed with a lid. If the burner is in operation it is forbidden to place hands to the

combustion chamber or feed screw.

DUST-FREE SURROUNDINGS OF THE BURNER

If the burner is in operation it sucks in the air from its surroundings. The operator must ensure

dust-free surroundings of the boiler. When handwork or cleaning must be carried out near the

burner we recommend turning the burner off and covering it (with nonflammable covering) so that

dust particles (e.g., also from the fuel) would not get into the inner space of the burner. (Metal dust

which is produced for example during sawing or grinding of metal is particularly dangerous).

There is a risk of clogging and damaging of the fan, damaging the electronics and the

ignition body of the burner. Defects caused by dust are not covered by the warranty.

24. SHUT-DOWN

Upon long-term shut-down of the boiler it is necessary to push the fuel from the entire feed screw

because the fuel may expand in the feed screw and clog it entirely, so that after having restarted

the boiler the transmission is not able to overcome the resistance.

25. CLEANING THE BOILER

During operation, carbon particles and ashes deposit of the walls, which reduces the efficiency of

the boiler. The amount of carbon particles and tar-clogging of the boiler, if any, depends on the



operation of the boiler, type of fuel used, size of the chimney draft, and temperature of the

discharge water from the boiler. The boiler is to be cleaned as necessary and according to the

operating conditions approximately twice a month. It is advisable to add flue gas thermometer to

the flue-gas ducting and clean the boiler in the event of increased temperature of the flue gas.

After termination of heating remove the lid of the exchanger. Then remove the swirlers from the

exchanger area. Clean the exchanger with cleaning tools which are supplied with the boiler.

Carbon particles fallen to the chamber under the exchanger are to be removed through the smut

door.

DESCRIPTION OF MAIN PARTS OF THE BURNER

Rotation cylindrical burning chamber

It is new revolutionary technical solution for burning agricultural pellets with ash clinkers



Feeding auger

Transports and accurately doses the fuel into the combustion chamber according to the set power

output.

Controlled fan

Speed control fan allows you to set ideal combustion for a particular fuel.

Ignition Unit

Enables burner to have interrupted operation (automatic switch off and on) regarding to

customer’s heating system needs.

Photocell

Sees light emitted by flame in the boiler and decides when to start and when the fire is already

started.

Rotation Flap (tourniquet)

Effective protection against backfire.

Pellet level sensor

Captures level of pellets in the burner above rotary flap (turnstile) and thus regulates the flow of

fuel into the burner from the external fuel tank by screw conveyor.

Control Unit

CU sets ignition, combustion, and burner power output for individual fuels. It also monitors and

records operational data.

Improper adjustment of the burner may cause malfunction or damage to the boiler.

31. DESCRIPTION OF THE FUNCTION

H 15 Petrojet pellet burner ignites the fuel automatically. Operation of the burner is controlled via

the flame sensor – photocell. In the burner body the fuel and the combustion air are fed in order to

achieve complete, effective and environment-friendly combustion of the pellets with high

efficiency.

FEEDING SYSTEM

The pellets are fed into the burner from an external fuel container automatically by means of a

feed screw PETROJET which is adapted and controlled by the burner electronic control unit. The

feeding system always uses the safe principle of interruption of fuel supply to the burner due to the

gravity feeding of pellets to the burner (empty hose above the burner).

If the LED is lighted up the feed crew is not moving. As soon as the LED turns off the feed screw

feeds up to the required level of fuel. Sensitivity of the capacity sensor can be adjusted by the

built-in trimmer (screwdriver maximum 1 mm).



WARNING – It is forbidden to combine the burner with a different feeding system. It is

necessary to use PETROJET fuel feeder.

32. SAFETY AND START-UP

DESIGN MEASURES FOR INCREASED SAFETY

In terms of safety the separation of the burner from the fuel container provides a high guarantee

against burning of fuel outside of the combustion area of the burner.

In the event of a failure the safety thermostat of the boiler will turn off the power supply to the

burner, preventing overheating of the boiler and burner. In addition, the burner is designed to

switch back automatically to normal operation after power supply outage.

In the event of a failure which results in interruption of the burner operation such failure is

indicated on the burner display.

• The process of igniting, burning and shutting down is controlled by a microprocessor logical

circuit with optical separation of the power leads to 5kV.

• The processor keeps checking flawless operation of the fan by means of a feedback loop. If

for some reason the fan is not running it will empty the pellets from the rotary combustion

chamber of the burner and shut down. It will indicate ERROR AIR message, and the boiler

waits for operator intervention.

• The first processor permanently monitors the fuel level using the pellet level sensor.

• The burner is protected against back-firing by a rotary gate (star feeder) and also by

complete emptying of fuel from the burner upon shut-down.

• If the burner fails also in the second attempt to ignite the fuel it will indicate ERROR START

message, and the boiler waits for operator intervention.

• If pellets run out during the burning the burner will shut down. The ERROR PELETS

message will be indicated, and the boiler waits for operator intervention. Important: Do not

forget to provide pellets to the feed screw always before starting up.

33. MAINTENANCE OF THE BURNER, BOILER, FLUE-GAS

DUCTING AND CHIMNEY

CHECKING AND CLEANING

The burner itself is designed to require only minimum maintenance. The maintenance frequency

depends on the quality, moisture and type of fuel burnt, and of course by the adjustment of the

burner. The actual consumption of pellets always depends on regular cleaning of the boiler and

the flue-gas ducting.

With respect to these facts, the operator himself must select the intervals of cleaning in order to

ensure reliable and safe operation of the boiler.



Basic maintenance of the burner

We recommend cleaning the rotary combustion chamber on regular basis once a month using a

wire brush. When burning fuel of lower quality where the ashes get stuck to the rotary combustion

chamber or where the combustion air supply openings get clogged clean the burner once a week.

The rotary combustion chamber may be cleaned only after the fuel has completely burned and the

combustion chamber has cooled down in the “STOP - -“ mode while the fan is running.

34. REQUIREMENTS FOR THE BOILER ROOM AN

CONNECTING THE BURNER TO THE BOILER

CAUTION – It is necessary to comply with all general safety regulations for working with

heating devices as stipulated by the applicable legislation. The boiler may be only started

if the burner is properly connected to the boiler, the boiler is connected to the chimney

with sufficient draught using the flue-gas ducting, and there is enough fuel in the fuel

container.

Requirements for the boiler room, system, burner, feed crew and pellet container

before starting the burner:

• The area where the boiler will be installed must conform to all fire regulations according to

the applicable standards and laws.

• The area where the boiler will be installed must be equipped with an opening for

combustion air suction with minimum section of 350 cm2.

• The boiler with the burner must be placed in such a way as to provide sufficient space for

cleaning and removal of ashes from the burner, boiler, flue-gas ducting and chimney.

• The burner must be installed on the boiler using insulation and sealing material and must

be properly attached with nuts to prevent leakage of flue gases to the boiler room.

• The external feed screw must be placed in the container in a way as to allow easy collection

of pellets.

• The hose between the burner and the feed screw must be fastened, properly attached, and

must have such gradient to allow the pellets fall to the burner without problems. The length

of the hose should be not longer than 50 cm. The joints between the hose, the burner,

and the feed screw must be properly tightened.

• The cable from the feed screw must be plugged in the socket on the burner.

H 15 Petrojet boi lers with burner can be used in the “basic environment”, AA5/AB5 pursuant

to ČSN3320001. The boilers must be placed in a boiler room which is provided with sufficient air

inlet for combustion. Installation of the boiler in a residential area (including hallways) is not allowed.

The section of the opening for combustion air inlet to the boiler room must be at least 350 cm2.



35. CONNECTING TO POWER SUPPLY

After the burner has been installed on the boiler the burner must be connected to power supply

through the boiler (never directly) according to the wiring diagram attached.

• After the burner has been installed the technician will connect the burner to the boiler using

a special cable which is a part of the burner.

• The feed screw is connected using a special plug and socket and is controlled by the

burner electronics according to the signals of the level sensor.

WARNING – The electrical parts must be connected by a qualified person, and particular

attention must be paid to safe grounding of the appliance. The connection is pictured in

this manual.

A four-core cable comes out of the burner and is to be connected to the boiler. The wires have the

following meaning:

• Black-phase (230V, 50 Hz) – The black wire is to be connected to the boiler terminal which

is permanently energized when the main switch is on, independent of the control thermostat

of the boiler. This is the supply voltage of the burner.

• Brown-phase (230V, 50 Hz) – The brown wire is to be connected to the terminal controlled

by the control thermostat of the boiler. It brings in the phase with the same polarity as the

supply voltage activating the start of the burner. It is perceived as a start-up (ignition) and

shut-down signal.

• Blue-N-neutral – The wire is to be connected to the neutral conductor.

• Yellow/green-PE – ground – The yellow/green wire is to be connected to the ground.

WARNING – Both phases (black and brown lead) must be always protected via safety

thermostat of the boiler.



36. BOILER GUARDING TEMPERATURE SWITCHBOARD SCHEME

37. CONTROL PANEL

+ – signs following the START / RUN / STOP

function indicate the following:

The first + or – sign indicates:

switched-on (+) control thermostat on the boiler panel

switched-off (+) control thermostat on the boiler panel

The second + or – sign indicates:

the photocell sees (+) flame; the photocell does not

see (–) flame

The Star indicates running of ignition unit

The values can be changed using buttons. With the ENT button the program will always

change to the next variable, and so on. The ESC button allows you to return to the main menu.

When setting specific values follow the other instructions in the manual.



38. SWITCHING ON – OPERATION – SWITCHING OFF

WARNING – The first start-up of the burner after installation must be always carried out

by an authorized technician.

CAUTION – During the first heating-up the surface paint and graphite sealing of the

rotary combustion chamber are burnt; the associated smoke or odor will disappear after

few hours of operation. It is not a defect.

PREPARATION OF THE BOILER AND BURNER FOR OPERATION

Before the initial start-up of the burner first check whether the burner is properly attached to the

boiler, so that no gases produced during the burning of the fuel could leak to the boiler room area.

Check the position of the burner with a spirit level (it must be horizontal). Check the position of the

external feed screw in the fuel container so that its angle does not exceed 45°. Then fill the

container with pellets. Cut the connecting hose between the external feed screw and burner to the

required length, fasten and fix properly.

Then start the burner according to the following instructions:

Starting the burner

• Switch on the main switch on the boiler

• On the control thermostat set the required output temperature of water at 70–90 °C, and

the difference between the switch-on and switch-off temperature 20–40 °C.

• The thermostat should be in the ON position before switching on the burner. If we switch on

the thermostat later the burner will go through the entire STOP mode (approximately 40

minutes) and only then will ignite.

• In the first phase the burner will check the inner level of pellets using the capacity level

sensor.

If the burner and feed screw is without pellets they will be automatically supplied (if they are in the

feed container). After the feed screw and the burner are filled with pellets the burner will

automatically ignite.

CAUTION – We recommend checking the level sensor settings before start. If the burner

is without pellets the LED will turn off, and the external feed screw will be filled or supply

the fuel from the container to the burner (the maximum permitted time of filling is 30

minutes).

AUTOMATIC IGNITION – START FUNCTION

Upon a command of the relevant thermostat the burner will switch from the STOP mode to the

START mode. If the photocell does not see any flame the cylindrical combustion chamber will turn

to a position for optimal access of the ignition hot air to the fuel. The fuel is poured into a

transparent plastic tube above the burner until it is detected by the capacity sensor. The internal



feed screw feeds the required amount of fuel for ignition to the rear section of the cylindrical

combustion chamber, and the electronic control unit starts the ignition. As soon as the photocell

detects flame the burner, after the run-out characterized by the PHOTOCELL parameter, will

switch to the operating mode RUN ST.

CAUTION – If the pellets cannot be ignited during the first attempt the entire ignition

cycle will be repeated. If the ignition is not successful at the second attempt the burner

will signal ERROR START message, it will shut down and wait for the operator’s

intervention. The operator must ascertain the cause of this situation. For example,

whether there is sufficient amount of pellets in the container, whether the external feed

screw is functional, whether the external feed screw or rotary gate are clogged by

impurities in pellets, whether the pellet level sensor is activated and the inside of the

burner clogged.

PARAMETERS UNDER THE START + - FUNCTION

The values can be changed using the buttons. With the ENT button the program will

always change to the next variable, and so on. The ESC button allows you to return to the main

menu. When setting specific values follow the other instructions in the manual.

CAUTION – The + – signs after the START/RUN/STOP function indicate the following:

the first + or – indicates a switched-on (+) or switched-off (–) control thermostat on the

boiler panel; the second + or – indicates whether the photocell sees (+) or does not see

(–) flame.

WARNING – We do not recommend that even trained operators change the parameters

under the START function. Unprofessional setup of the burner may cause dysfunction of

the burner or even damage some parts of the burner. Changes in the setup must always

be consulted with the authorized technician.

[AIR START] – Optimal amount of air required during ignition of the burner. It affects the speed of

ignition of the fuel.

[TIME PELETS] – The first batch of fuel required for optimal ignition of the burner.

[TIME START] – Time during which the burner tries to ignite the fuel. After the first unsuccessful

attempt the entire ignition cycle will be repeated. If the fuel cannot be ignited even during the

second attempt the burner will shut down to failure status, and ERROR START message will

appear on the electronic unit display.

[TIME STA D] – Interval of fuel feeding by the internal feed screw in the mode START and RUN

ST.

[FEEDR START] – Amount of fuel which the internal feed screw adds to the rotary combustion

will be terminated, the PHOTOCELL time will start counting, and the display will show START + +.

During the ignition process, operation and shut-down it is possible to watch the actual intensity of

light in the boiler in the menu SERVICE, CELA=0 - 100%. This indicator makes it easy to

determine how the photocell works and whether it must be cleaned. (Photocell in the RUN mode

(i.e., after the fuel has started fully burning) should indicate 100%; if the boiler is not burning and is

closed the photocell indicates 0%)

NORMAL OPERATION

Normal operation is entirely automatic while the operator replenishes the fuel, takes out ashes and

cleans the burner. During normal operation the display shows RUN ++ (or RUN ++ ST):

RUN + + ST

A mode to which the burner switches after ignition from the START mode. During this mode the

burner increases the burning and it lasts 10 minutes. After having achieved full burning the burner

then switches to the RUN mode.

RUN + +

The burner enters the RUN function in two ways.

1. After START and achieving full burning of the burner. 2. After a short-term power failure. If the photocell signals at this moment that it sees flame

the burner will automatically continue in operation (RUN).

The combustion process is set up under the RUN function – normal operation.

[ASH] – Only for automatic removal of ashes. Every 60 seconds the screw turns by the set value.

(not used)

Afterburning or the STOP process occurs as follows:

If the boiler thermostat which controls the operation of the burner switches off the burner will

switch to the STOP function. The following will occur during this function:

1. The feeding of the fuel to the burner by the external feed screw will stop. 2. The burner will switch to the mode of fuel afterburning in the rotary combustion chamber

which is characterized by the TIME STOP value. 3. After expiry of the TIME STOP time the burner will automatically switch to the mode of

cooling down and cleaning of the rotary combustion chamber. This function runs for a period of TIME END.

4. After expiry of this period the burner will switch to standby mode and wait for a new command to start and new ignition.

WARNING - Manual cleaning of the rotary combustion chamber is allowed only in this

status.

PARAMETERS UNDER THE STOP FUNCTION

in the range between 50 and 70.

39. ADJUSTMENT OF THE BURNER FOR DIFFERENT FUELS

WARNING – If the burner does not burn certified fuel or if it burns fuel which is not

mentioned in this manual the manufacturer is not liable for any damage to the boiler, the

burner, flue-gas ducting and chimney. The burner is not designed for burning coal.

Setting of the combustion parameters affects the quality of combustion and useful life of

the boiler and the burner. The output of the burner must be set such that the temperature

never drops below 130 °C during operation. This will prevent condensation of water vapor.

CAUTION – Initial adjustment and setup must be carried out by an authorized

technician.

This professional adjustment of the burner is a condition for warranty liability to the

consumer and must be recorded in the attached operation manual.

40. OTHER IMPORTANT INFORMATION – FEED SCREWS

• Only feed screws PETROJET 1.7 m through 4 m shall be used for the H 15 burner.

41. TROUBLESHOOTING

Defect Check Action

The display is not lighted up

Check the power supply to the

boiler If the cause cannot be

established for sure contact an

authorized technician Check how the connector is

plugged in the burner

The display is lighted up but

the boiler does not feed pellets Check whether the container is

filled with pellets Replenish the pellets

Check whether the screw of the external feed screw is

Clean up the external feed screw



jammed with a foreign object

Check whether the external feed screw is functional (i.e., whether the pellets are fed)

Contact an authorized technician

Check the control and safety thermostat on the boiler control unit

Switch off and back on the main switch on the boiler. Use a pencil to push the safety thermostat

Check the level sensor settings

Clean and, if applicable, adjust

the sensitivity by the trimmer on

the capacity sensor. (reduce

sensitivity to the left, increase

sensitivity to the right)

The burner will not start (ignite) Check whether the ignition

element is running

Check whether hot air is

coming out of the rotary

combustion chamber

Other defects are indicated by the burner directly on the control display.

If the boiler does not run optimally and the cause cannot be identified contact an authorized

technician.

42. ERROR MESSAGES

The burner is equipped with a system of error indications which are displayed as text. This alarm

makes it easier to look for defect, if any, by displaying the cause of stopping. After rectification of

the defect restart the burner by switching off and on the main switch on the boiler.

ERROR START

This error message will be indicated on the display in a situation where the fuel could not be

ignited not even with the second attempt. The burner will shut down and wait for the operator. The

operator must identify the cause of this situation. For example, whether there are enough pellets in

the container, whether the external feed screw is functional, whether the external feed screw or

rotary gate are clogged by impurities in pellets, whether the pellet level sensor is activated and the

inside of the burner clogged, whether the pellet level sensor in the burner is blocked by an object

from the pellets, etc.

ERROR PELETS

This error message will be indicated on the display after the burner tries to feed pellets to the

external feed screw and the upper orifice of the burner up to the level of the capacity level sensor

for more than 30 minutes. The burner will shut down and wait for the operator. The operator must

identify the cause of this situation. The cause is usually insufficient amount of pellets in the

container or clogging of the external feed screw for pellets. Both situations must be resolved by

the operator.

ERROR AIR

This error message will be indicated on the display in a situation where the actual revolution of the

fan does not reach the programmed values with a certain permitted deviation. This is a loop check

of exact operation of the fan which affects the quality of combustion and safety of the operation.



The burner will shut down and wait for the operator. The operator must identify the cause of this

situation. The cause is usually operation in dusty environment.

WARNING – If the burner cannot be put to operation it is necessary to call a specialized

service.

43. SOME RECOMMENDATIONS REGARDING PELLETS AS

FUEL

Pellets as fuel can be made of several energy-carrying raw materials. The most common raw

material is wood, although today there are several alternative raw materials out of which fuel

pellets can be produced. These raw materials have different characteristics which are both

suitable and unsuitable for burning pellets. Important factors which should be checked when

buying pellets are: energy value, size, small particle content, moisture and – last but not least –

the price.

We recommend choosing fuel which has the lowest cost per energy unit with respect to the

function of the fuel in the boiler. Study the function carefully after the fuel delivery. Majority of

defects which can occur as a result of poor-quality fuel is related to the handling of the fuel,

storage of the fuel in intermediate warehouses, i.e., over the time before it gets to the end user.

High content of small particles is often a result of spalling of the pellets during storage or at the

place of storage. Formation of sinters in ashes also depends on the silicate (inorganic) impurities

(sand). These cannot be detected other than during operation. Moist pellets can be a result of

storage in the intermediate warehouse and due to the transport. For the latest knowledge about

burning see www.horakypetrojet.cz.

WARNING – When burning wood pellets there is approximately 0.1% to 2% of ashes.

When burning biomass pellets there is a greater amount of ashes produced (3–20%).

The time of checking the amount of ashes in the ash tray must be adapted to this fact.

installation of the boiler in an unsuitable environment (e.g., high humidity or dust in the

boiler room)

violent handling, tampering with the boiler structure, natural disaster, improper storage

4) The condition of validity of warranty liability is filling-out and signing of the “Handover protocol -

Training and Burn-in” by the customer and an authorized technician.

5) The buyer has been demonstrably informed of the method of use and operation of the boiler

and has acknowledge this by signing the “Protocol of operator training and initial start-up”

6) Burning of other than the certified or tolerable fuel is the buyer’s own responsibility.

7) The warranty sheet provided to the consumer must be properly filled out. The information on

the person (company) installing the boiler must be legible and complete.

8) The boiler must be operated only in the manner specified by the operation manual.

9) The warranty does not apply to wear and tear of the boiler caused by normal use, incorrect

change of parameters of the electronic control of the burner, and defects which have been

caused by the user’s violation of the above warranty terms.

the vendor (contractor). For information on the current service network of authorized

technicians please visit: www.horakypetrojet.cz

http://www.horakypetrojet.cz/



47. TRAINING AND INFORMING THE OPERATOR ABOUT

PB15 AND PB30

1) Provision of information on each point of the Operation manual and explanation thereof.

2) The operator must ensure quality of the fuel used. The fuel must not be frozen, wet,

extremely spalled, and must not contain nonflammable additives. Other than the tolerable or

certified fuel described in this manual is burned at the operator’s own responsibility.

3) The boiler operator must not switch off the boiler during operation using the main switch (with

exception of a situation where the container runs out of fuel and the system must be

restarted or where there is a risk to the lives or health of people or damage to property). The

cycle of complete burning of fuel and removal of ash from the combustion area of the burner

would not be completed. This would limit easy re-ignition of the fuel. Repeating this incorrect

action might damage the ignition element and clog the nozzles with unburned fuel or cause

other defects.

4) The boiler operator has been informed of all functions in the menu of the electronic control

unit of the burner and the way they affect the burning process.

5) Upon changes of the settings of the electronic control unit made by the operator it is always

necessary to wait at least twenty minutes after every intervention for the change to take

effect. This delay is necessary because the fuel from the previous setting must burn out. We

recommend that the setting step be always in units of per cent and the fuel feeding time in

seconds.

6) WARNING – a small change, e.g., 2%, in the setting of the amount of air will induce a

change in the combustion.

7) If the fuel is completely exhausted the boiler must be restarted. This means disconnecting

the boiler from the power mains by the main switch on the boiler body or on the power supply

for the boiler with burner.

8) We recommend recording the setting which was suitable for different fuels in the boiler

operation log for future easy adjustment when re-using the same fuel.

9) The operator must perform a visual and listening check along with the check of filling of the

ash tray every 24 hours of the boiler operation.

10) You can file requests for repairs at the following telephone number: +420608955676. This does not affect the obligation to claim the rights arising from liability for defects with the vendor (contractor).
