5.1.1 Information about the soft water supply

Cl/Fe content If the Cl content is greater than 150 mg/l, Fe content greaterthan 0.1 mg/l or Cl2 content greater than 0.1 mg/l, corrosion can occur

in the cooking chamber. The Cl content can be reduced with anactivated charcoal filter.

Supply pressure If the supply pressure is not within the given limits (see Chapter“Specifications, soft water”, Page 17), the cooking art “Steaming” willfail to produce any steam.

Contamination of the water If the water is heavily contaminated, a sedimentation filter (grit size0.08 mm) must be installed upstream.

Water hardness Scale deposits may form if the total water hardness or carbonatehardness exceeds 5 °dH (0.89 mmol/l). For values smaller than this,the scale formation is correspondingly less. A total water hardness or

carbonate hardness of 1 °dH is ideal. Certain water components (Na+

ions and silicates) can cause the windows to become cloudy.This effectdepends on the quality of the water and how the unit is used.Decarbonisation or full desalination systems can prevent the formationof scale deposits.

A water softening system should be installed upstream if the water isvery hard.

Water softening systems based on electromagnetic fields do not provideprotection against scale deposits with combisteamers.

Pipes from galvanized steel or other corrosive material may not beused downstream from water softening systems.

Systems with phosphate and silicate dosing may not be used. Depositsmay form in the cooking chamber with such systems.

SmartCombi units can show the service intervals of a connected watersoftening system on the multi-function display.You will find furtherinformation in the operating instructions.

5.1.2 Information about the hard water supply

Cooling waste steam Cold water that has not been softened can be used for cooling wastesteam.



Warm water leads to increased water consumption and should not beused.

The water temperature must not exceed 50 °C (122 °F).

Automatic cleaning system“WaveClean”

Units that are equipped with the “WaveClean” automatic cleaning systemmust always be connected to a hard water and a soft water supply.

Otherwise, cleaning with “WaveClean” is not possible.

5.1.3 Fitting the T-piece (accessory)

Hard and soft water connections can be made via a hose with a T-piece(accessory) in the event that only soft water is available on site.

6.3 Hose connectionGas hose and fitting

connections in the sameplane

Left: correct; Right: incorrect

If the connection points are laterally offset, this will cause additionaltorsional stress and heavy strain on the hose. This leads to prematurefailure.

Connection with a metalhose


Make sure that the hose has only one bend. A strained or twisted metalhose can lead to early failure of the connection.

Minimum bendingdiameter




If the separation between the two connection points is less than theminimum bending diameter, it results in the hose ends bending in oppositedirections. This leads to fatigue fractures.

7 Exhaust gas routingWARNING

Risk of fire due to combustion gases and hot surfaces

The exhaust flue connection and its covering can become extremelyhot and cause burns in cases of direct contact.

→ The temperature of the exhaust gas can reach 400 °C (752 °F).Plan and carry out the installation of the unit in such a way as toavoid contact with flammable surfaces.

→ Do not place any objects close to or on the unit.→ Maintain sufficient distance to fat filters in customer supplied

extraction hoods.→ Use a ventilation cover (accessory) to reduce exhaust temperatures.→ Only allow gas supply to the burners when the extraction system

is working.

WARNINGDanger of poisoning by exhaust fumes

→ Ensure, during planning and installation, that exhaust fumes aretransported to the open air.

→ Install extraction systems such as extraction hoods, chimneys andventilation covers.

→ Ensure that all users know the fire prevention regulations.

NOTICEIn order to prevent an unacceptable build-up of harmful combustionproducts, the units must be installed under extraction systems (roomventilation system with safety switch). When installing the appliancebeneath a ventilation cover or an extractor hood system, safety devicesmust be in place that allow gas supply to the burners only when theextraction system is working.

The following exhaust gas evacuation paths are possible (according toDVGW worksheet G634):

B23A3

Extractor hood

● For units of type A3 (size 615)● For units of type B23 (all other sizes)


SmartCombi™ClassicCombi™Exhaust gas routing

B13B13

Chimney

For units of type B13 (optional, possible for all versions).

When connecting appliances to a chimney, all exhaust gas paths mustbe cleaned regularly.

Ventilation cover

For units of type B13 (optional, possible for all versions).

1. Observe the regulations for room ventilation systems (see Chapter“Room air”, Page 8).

2. Observe country-specific regulations.

3. Exhaust gas systems are to be agreed with the districtchimney/heating inspector and documented.

4. Make sure that the pipes have leak-proof connections and lay themaccording to the technical regulations governing liquid gas and gasinstallations (see Chapter “Gas”, Page 6).

5. Secure the unit against being moved.


Exhaust gas routingSmartCombi™ClassicCombi™

8 Air outlet connectionWaste steam and vapours are cooled by the built-in cooling system andextracted via the drain; an air extraction system is therefore not essential.

Installation under an extraction hood is recommended.

8.1 Installation under an extraction hood→ Observe the regulations for room ventilation systems (see Chapter

“Room air”, Page 8).

8.2 Connection to an air outlet ductRequirements Connection with a pipe

● Do not use galvanized pipes.● Heat-proof and non-corrosive pipe (e.g. PA-I 1818 DIN 19560 HT

pipe)Connection with a hose

● Do not use aluminium tubes because tube corrosion might occur.● Heat-proof to at least 180 °C (356 °F)● Hose diameter

With tabletop units: 53 mmWith floor standing units: 73 mm

● Hose length max. 2.5 m

The end of the hose must not be connected directly to an air-outlet duct(e.g. extraction hood). Counter-pressure will cause steam to be drawnoff from the cooking chamber; this will impair the cooking results. Theend of the hose should end below (outside) the air-outlet duct.

1. Connect the unit to an air-outlet duct using a pipe or a hose.

2. Take care not to create a “water pocket” (sagging when laidhorizontally), and that the cross-section is not restricted.
