3 Safety
What to do in an emergency if you smell gas
A malfunction may mean that gas is leaking and there
may be a risk of poisoning or explosion. If there is a
smell of gas in the building, proceed as follows:
> Avoid rooms that smell of gas.
> If possible, open doors and windows fully and ensure
adequate ventilation.
> Avoid the use of naked flames (e.g. lighters, matches).
> Do not smoke.
> Do not use any electrical switches, mains plugs, door-
bells, telephones or other intercommunication sys-
tems in the building.
> Close the gas meter isolator device or the main isola-
tor device.
> If possible, close the gas stop cock on the unit.
> Warn other occupants in the building by yelling or
banging on doors or walls.
> Leave the building.
> If you can actually hear gas leaking, leave the building
immediately and ensure that other persons do not
enter the building.
> Alert the fire brigade and police when you are outside
the building.
> Use a telephone outside the building to inform the
emergency service department of the gas supply
company.
What to do in an emergency if you smell flue gas
A malfunction may mean that there is a smell of flue gas
and may lead to a risk of poisoning. If there is a smell of
flue gas in the building, proceed as follows:
> Open doors and windows fully and ensure air is circu-
lating.
> Switch off the gas-fired wall-hung boiler.
Material damage caused by corrosion
To prevent corrosion on the unit and also in the flue
installation, note the following:
> Do not use any sprays, solvents, chlorinated cleaning
agents, paint, adhesives or similar substances in the
vicinity of the unit.
Under unfavourable circumstances, these substances
may cause corrosion.
Preventing frost damage
If there is a power cut, or if the room temperature is set
too low in individual rooms, it cannot be ruled out that
sections of the heating system might be damaged by
frost.
> If you are going to be away during a cold period,
make sure the heating system remains in operation
and that the rooms are sufficiently heated.
> Please always observe the instructions concerning
frost protection in section 6.1.

Maintaining operation in the event of a power cut
Your competent person connected your gas-fired wall-
hung boiler to the power mains during installation. If the
power supply is cut, it is possible that parts of the heat-
ing system may be damaged by frost. If you want to
maintain the operation of the unit during a power cut
using an emergency power generator, take note of the
following:
> Make sure that the technical values of this generator
(frequency, voltage, earthing) match those of the
power mains.
Material damage due to improper use and/or unsuita-
ble tools
Improper use and/or unsuitable tools may result in
material damage (e. g. gas or water leaks).
> Always use a suitable open-ended spanner to tighten
or undo threaded connections.
> Do not use pipe wrenches, extensions, etc.
Changes to the surroundings of the boiler
Changes may not be made to the following equipment:
– the boiler
– the gas, air, water and electricity supply pipes
– the exhaust gas delivery pipe
– the drain line and expansion relief valve for the heat-
ing water
– the structural conditions that could affect the opera-
tional reliability of the unit
Important note on operation with liquid gas
Venting the liquid gas tank during installation:
If the tank is not vented properly, this may result in igni-
tion problems. You must therefore observe the following
when installing the system:
> Before installing the unit, make sure that the gas tank
has been vented.
The liquid gas supplier is responsible for ensuring that
the tank is vented properly. In such cases, first contact
the person in charge of filling the tank.
> Also observe the information on conversion to liquid
gas in section 6.2 of these instructions.
Installation below ground level
> For installation in rooms below ground level, you must
observe the national regulations.
We recommend that you use an external solenoid valve
(to be fitted on-site). You can connect the external sole-
noid valve directly on the PCB or via the add-on mod-
ule "2 in 7".
Avoid incorrect gas types:
Use of the wrong type of gas results in ignition and com-
bustion noises as well as fault shutdowns. You must
therefore take note of the following:
> Affix the enclosed tank sticker (propane quality) to
the tank or cylinder cabinet where it is clearly visible,
if possible close to the filler nozzle.
