INSTALLATION
Read all instructions before starting work so installationwill conform to Underwriters' Laboratories or CanadianStandards Association requirements.The furnace must belevel when placed on its foundation (upflow, counterflow,and basement models) or in its suspended position(horizontal models). Using a carpenter's level, check thefurnace in at least two directions. The weight must bedistributed evenly before the duct work is attached.
These instructions must be placed on or near thefurnace in a conspicuous place.
Inspection of Shipment
This furnace is shipped in one package, completelyassembled and wired. The thermostat is shipped in aseparate carton when ordered.
Upon receipt of equipment, carefully inspect it for possibleshipping damage. If damage is found, it should be noted onthe carrier's freight bill. Damage claims should be filed withthe carrier immediately. Claims of shortages should befiled with the seller within 5 days.
Location
Locate the furnace as centrally as possible so that allwarm pipes to the various rooms are nearly the samelength. This allows each room to receive an equal andproper amount of heat. This may vary with each particularinstallation. Position the furnace so the pipe connection tothe chimney will be of minimum distance and have aminimum of fittings.
In utility rooms or similar installations, the door or accessopening should be large enough to permit replacement ofthe furnace, or another appliance such as a water heater,without disturbing any other equipment.
The R/LHR 196 rear flue models are approved forhorizontal applications only.
A WARNINGIn any installation where damage from oi! mayoccur, a drain pan must be installed. The drainpan must be large enough size to completelyprevent any potential oil damage. The drainpan piping must be sized to drain the oil pumpcapacity and the piping must be routed todrain the oil back to the oil tank.
For attic installations, a booster oil pump may be requiredto supply oil to the oil burner. Check state and local codesfor specific requirements.
Clearances
A minimum of 24" is recommended in front of the furnacefor servicing the burner on all modeis.
See Table 1 for a complete listing of the minimum clear-ances required for basement type and upflow installations.See Figure 2 on page 4 for the minimum clearancesrequired for horizontal installations and Figure 3 on page 5for the minimum clearances required for counterflowinstallations.

It is very important that the furnace be exactly levelsince a levei unit is necessary for proper fitting ofparts. Using a carpenter's level, check the furnace in atleast two directions. If the furnace is not level, placefireproof wedges or shims between the low side ofthe furnace and the floor and check again with the
#41996B002 Page 5Provided courtesy of www.alpinehomeair.com
level. The weight of the unit must be distributedevenly on all four corners.
Air Conditioning
A WARNINGWhen an air conditioning unit is used in con-junction with the furnace, the evaporator coilmust be installed in the discharge (supply) air.Do not install an evaporator coil in the returnair; excessive condensation will occur withinthe furnace. < <; $
Venting
AWARNINGCombustion air openings in the front of thefurnace must be kept free of obstructions. Anyobstruction will cause improper burner opera-tion and may result in a fire hazard or injury.
The barometric control shall be in the sameatmospheric pressure zone as the combustionair inlet to the furnace. Deviation from thispractice will cause improper burner operationand may result in a fire hazard or injury.
Combustion and Ventilation Air
Adequate provisions for combustion air, ventilation offurnace, and dilution of the gases must be made. When afurnace is installed in an unconfined space in a building, itcan be assumed that infiltration will be sufficient to supplythe required air.
If the furnace is installed in a confined space and combus-tion air is taken from the heated space, the supply air andventilating air must be through two permanent openings ofequal area. A confined space is "a space whose volume ismore than 50 cubic feet per 1000 BTU per hour of thecombined input rating of all appliances installed in thatspace." One opening must be within 12" of the ceiiing andthe other within 12" of the floor. Each opening must have aminimum free area of at least 1 square inch per 1000 BTUper hour of total input rating of all appliances within thespace but not less than 100 square inches.
If the furnace is installed in a space within a building oftight construction, air must be supplied from outdoors. Inthis case, one opening shall be within 12" of the ceiling
and the other within 12" of the floor. If vertical combustionducts are run, each opening must have a free area of atleast 1 square inch per 4000 BTU per hour. If horizontalcombustion ducts are run, 1 square inch per 2000 BTU perhour of the total input of all appliances is required.
A return air duct system is recommended. Where there isno complete return air duct system, a return connectionshould be run full size to a location outside the confinedspace and completely sealed so that no air from theconfined space can be circulated through the heating ductsystem.
Outdoor Make Up Air
A minimum mixed return air temperature of 60 - 65°F mustbe maintained for outdoor make up air to prevent conden-sation and corrosion.
Chimney
Before installing the furnace, a thorough inspection of thechimney should be made to determine whether repairs arenecessary and that the chimney is of the proper size andconstructed in accordance with the requirements of theNational Board of Fire Underwriters or Canadian StandardsAssociation. The smallest dimension of the chimneyshould be at least equal to the diameter of the flue pipe ofthe furnace. Be sure the chimney will produce a steadydraft sufficient to remove all the products of combustionfrom the furnace. A fabricated vent system the same sizeas the flue outlet of the furnace may also be used. If amanufactured vent is used, it must be listed for use withoil-fired equipment.
Vertical Venting
A WARNING
This furnace is certified for use with Type "LTvent, Type "A," and "factory-built" chimneys. "B"vent must not be used with oil furnaces.
1. Local building codes may have more stringent installa-tion requirements and should be consulted beforeinstallation of the unit.
2. The flue pipe should be as short as possible to do thejob.
3. The flue pipe should not be smaller than the outletdiameter of the flue outlet of the furnace.
4. Single wall flue pipe should not run outside or throughany unconditioned space.
5. The chimney should terminate 2' above the highestpeak of a peaked roof, and 3' higher than a flat roof.

8. The flue pipe should slope upward toward thechimney on a horizontal run of at least 1/4" perfoot and should be supported by something other thanthe furnace (see Figure 6 on this page and Figure 7 onpage 8).
9. Extend the flue pipe into the chimney so that it isflush with the inside of the flue liner. Seal the jointbetween the pipe and the liner.
10. The furnace shall be connected to a factory-builtchimney or vent complying with a recognized stan-dard, or a masonry or concrete chimney lined with alining material acceptable to the authority havingjurisdiction.
11. When two or more appliances vent into a commonflue, the area of the common flue should not be lessthan the area of the largest flue or vent connectionplus 50% of the areas of the additional vents or flueconnections. The chimney must be able to sufficientlyvent all appliances operating at the same time.
12. The flue pipe shall not be connected to a chimneyflue serving a solid fuel appliance or any mechani-cal draft system.
13. All unused chimney openings should be closed.

Removal of Unit from Common Venting System
When an existing furnace is removed from a commonventing system serving other appliances, the venting
#41996B002
Provided courtesy of www.alpinehomeair.com
system is likely to be too large to properly vent theremaining attached appliances.The following test shouldbe conducted with each appliance while the other appli-ances connected to the common venting system are not inoperation.
1. Seal any unused openings in the common ventingsystem.
2. Visually inspect the venting system for proper sizeand horizontal pitch and determine there is no block-age or restriction, leakage, corrosion, or other deficien-cies which could cause an unsafe condition.
3. Insofar as is practical, close all building doors andwindows between the space in which the appliancesremaining connected to the common venting systemare located and other spaces in the building.Turn onclothes dryers and any appliance not connected to thecommon venting system.Turn on exhaust fans, suchas range hoods and bathroom exhausts, so they willoperate at maximum speed. Do not operate a summerexhaust fan. Close fireplace dampers.
4. Following the lighting instructions, place the unit beinginspected in operation. Adjust the thermostat so theappliance will operate continuously.
5. Test for spillage at the draft control relief opening after5 minutes of main burner operation. Use the flame of amatch or candle.
6. After it has been determined that each applianceremaining connected to the common venting systemproperly vents when tested as outlined above, returndoors, windows, exhaust fans, fireplace dampers, andany other fuel burning appliance to their previouscondition of use.
7. If improper venting is observed during any of theabove tests, the common venting system must becorrected. See National Fuel Gas Code, ANSI Z223.1(latest edition) or CAN/CGA B149.1 & .2 InstallationCodes to correct improper operation of commonventing system.
Smoke Pipe and Draft Control
Connect the furnace vent to the chimney with galvanizedsmoke pipe and fittings, maintaining full diameter offurnace vent throughout. No reduction in diameter of pipe isallowed. It is best to have smoke pipe as short and directas possible. The smoke pipe shall maintain a rise of atleast 1/4" per foot. Install draft control at least 12" beyondthe furnace. If there is no space to install the draft controlin the smoke pipe, it may be installed in the chimneyabove the smoke pipe (see Figure 9).

Supply and Return Air Plenum
Secure return air plenum to unit using sheet metal screws.
Follow these procedures when installing the supply airplenum:
1. Use sealing strips of fiberglass.
2. Attach the plenum to the furnace or evaporator cabinetwith sheet metal screws.
3. Both supply and return air plenums shall be squareand at least 18" long.They should be the samedimension as the furnace opening.
4. Install supply and return air ducts as desired.
Oil Supply and Oil Filter Connection
Continuous lengths of heavy wall copper tubing or steelpipe are recommended and should be installed under thefloor or near walls to protect from damage. Do not run lineson floor joists or other reverberating surfaces. Always useflare fittings located in accessible places.
Install a generous capacity oil filter inside the buildingbetween the fuel shut-off valve and the burner. Locate filterand valve close to the burner for easy servicing. A10-micron filter is recommended.
An oil filter is required for all models.

Combustion Chamber
The combustion chamber is installed in the furnace at thefactory. Read the instruction plate on the front of the unitconcerning proper care of the chamber.
This combustion chamber is made of preformed ceramicfiber material. Use extreme care when installing the oilburner so that the chamber is not damaged around theburner tube.
Fan & Limit Control
The fan & limit control is installed and wired at the'factory.Replacement of the fan & limit control must be made with anidentical control as originally supplied on the equipment fromthe factory including "fan" and "limit" stops. The use of anyother controls will void the warranty of the furnace. Operationof this furnace with greater than 130°F"Fan On" air tempera-ture will also void the warranty of the furnace.
Electrical Wiring
All wiring must conform to the National Electrical Code, theCanadian Electrical Code, and any local codes. Connectthe 115-volt, single phase service to the unit at thejunction box. Use a separate fused branch electrical circuitcontaining a properly sized fuse or circuit breaker. Run thiscircuit directly from the main switch box to an electricaldisconnect that is readily accessible and located near thefurnace. Follow carefully the wiring diagram adhered to theinside of the blower compartment door.
The electrical supply to the mechanical vent system mustbe supplied from the appliance. All wiring must be appropri-ate Class I wiring. Wiring must be installed in rigid metalconduit, intermediate metal, or be otherwise suitably pro-tected from physical damage. Refer to the wiring diagramssupplied with the venter kit for proper electrical connections.
Thermostat
Locate the thermostat on an inside wall in a room usuallyoccupied during the day, such as a living room or diningroom, at a height of 4-1/2' from the floor. Avoid directsunlight or supply air from a register. Make sure thelocation is not adjacent to appliances such as ovens orlights. Wire the thermostat with minimum of #18 AWGthermostat wire.
Humidifier
A humidifier can be installed with this furnace. Refer to thehumidifier manufacturer's instructions for specific connec-tion information (see also Figure 14 on page 16).
Electronic Air Cleaner
An electronic air cleaner can be installed with this furnace.Refer to the electronic air cleaner manufacturer's instruc-
tions for specific connection informatibn (see also Figure15 on page 16).

Table 2
Burner A djustment
All adjustment to this furnace and its componentsmust be done by a qualified service technician.
Refer to Table 2 for nozzle and pump pressure information.The proper way to adjust an oil burner is with a CO2
analyzer and a smoke gun. A properly adjusted burner willresult in a quiet, clean fire which will prevent sooting andfrequent cleaning. To establish tolerance or a "window ofoperation" into the unit, do not exceed #1 smoke. This willgive the burner more flexibility when there are changes inthe surrounding environment.To adjust the burner:
1. Operate burner continuously for 5 - 1 0 minutes.Thiswill purge the fuel lines and level out combustion.
2. Make sure all inspection openings are closed tightlyand all fitting joints between the furnace and the pointwhere CO2 and smoke readings are taken are tightlysealed or taped. An air leak at the inspection openingsor fittings wiil cause false COE readings.
3. Punch a 5/16" diameter service hole in the flue outletbetween the furnace and the draft control.Take draftreadings, CO2 readings, and the smoke test from thispoint.
4. Adjust barometric draft control in the stack to achievean overfire draft of .00" to -.02".
5. Loosen the air control adjustment screw on the bulk airband and rotate the band until the flame appears clean.Retighten the air control adjustment screw.
6. Take a CO2 reading at the service opening in the stackusing a C02 analyzer.
Beckett Oil Burner Nozzle Adjustment
Burner must be removed fromfurnace for this procedure.
Gauge
To adjust nozzle:
1. Loosen screw.2. Slide entire nozzle/electrode assembly back and
forth until nozzle just touches gauge.
Figure 10
7. Take a smoke reading using the same service hole.Use a standard smoke tester. If smoke is evident, itcould be caused by a poor nozzle or combustionsetting. In some cases, it may be caused by a differ-ence in oil or an unusual condition of installation.
Nozzle and Electrode Alignment
Proper nozzle and electrode depth and alignment areessential for proper burner operation. Figure 10 shows theproper adjustment procedure using the Beckett T" gauge.To check and adjust the nozzle depth:
1. Insert the small end of the "T" gauge into the end ofthe cone and measure from the flat of the end cone tothe tip of the nozzle.The proper measurement shouldbe 1.13". When the depth is correct, the tip of thenozzle should just touch the base of the "T" gauge.
2. Nozzle adjustments are made by sliding the entirenozzle assembly forward or backward within the blasttube (see Figure 10).
To check nozzle alignment:
1. Insert the small end of the T gauge into the end ofthe cone and measure the nozzle and electrodealignment against the center lines marked on thegauge.
2. If the nozzle is not centered, but found to be too farleft or right, a new nozzle will need to be ordered. Donot attempt to adjust by bending the 90° elbow inthe oil line.

SEQUENCE OF O P E H A I I U K
The thermostat calls tor heat, activating the venter motor.
After a 15-second pre-purge period, power is sent tothe burner and ignition is established.
After the thermostat is satisfied, the thermostat circuitwill open.
. Power to the burner is interrupted, thus shutting downthe burner.
If you are using the optional pre- and post-purge kit,upon the thermostat circuit opening, the post:purgetiming on the vent system and burner will initiate andthe oil valve will close.
Note: Post-purge timings are adjustable to suitindividual requirements. A 3- to 5-minute post-purge time is recommended, but may vary perapplication.
5. When post-purge time has expired, the venter motorand/or (if the pre- and post-purge kit is used) theburner motor will stop operation.
MAINTENANCE AND SERVICE
Flue Pipe
Have the flue pipe inspected annually by a qualifiedservice technician. If any soot or ash has formed insidethe flue pipe, remove and clean. If the flue pipe has anyholes or is rusted out, replace with a new flue pipe of thesame size. Inspect the flue draft control device andreplace if defective.
Blower
Blower motor is pre-lubricated and sealed for extendedoperation. No further lubrication is required.
The blower assembly may be removed from the cabinet forcleaning and servicing of the blower. Disconnect power tothe unit before servicing.
Heat Exchanger
To clean the heat exchanger:
1. Remove the vent pipe from the furnace.
2. Remove the locking screws and the caps from the twocleanout tubes; remove the flue access elbow.
3. Using a long spiral wire brush, sweep down the outerdrum of the heat exchanger. Using a shop vacuumhose attachment, vacuum out all loose debris.
tube and with the spiral wn c u,toward the rear of the heat exchanger to clean out thecrossover tube; replace the locking screw and cap onthe inspection tube.
5. Do not attempt to clean the combustion chamber, as ican be easily damaged.
6. Replace the three previously removed cleanout capsand flue access elbow, making sure to reinstall thelocking screws.
7. Brush out and vacuum the vent outlet area of theouter drum and reattach the vent pipe.
8. Clean up around the burner, blower deck, and vestibiarea.
Heat exchanger cleanout kit #ABRSH380-3 is availablefrom the manufacturer.
Emergency Fuel Pump Replacement
If replacement of the A2EA6520 fuel pump becomesnecessary, replace it with another Beckett CleanCut futpump. In an emergency situation where the correct re-placement parts are not available, an A2VA7116 fuel pcould be used.This option can produce a smoky start-and shutdown that could result in fouling of a heat ex-changer. This is only a short-term option and shoulused only until the correct parts can be obtainedinstalled.
