Installation and
maintenance information
- Your gas fired condensing boiler should only be installed and modified by an appro-
ved heating contractor, as only they have the essential knowledge to carry out such
work.
- Gas components must not be modified.
- Never close or restrict the ventilation apertures in doors or walls when operating
the boiler in the open flue mode; only start the boiler when the flue pipe has
been fully installed.
- Only take the boiler into use when operating the device in balanced flue mode, if the
balanced flue system has been fully installed and the wind protector is not covered
up.
- Gas fired condensing boilers may only be installed in rooms which are protected from
frost.
- Never isolate the condensing boiler from the power supply when outside temperatures
fall below freezing, otherwise there is a risk of the system freezing up.
- Do not modify the drain or the safety valve.
Please note - non-observance can create a fire hazard and a risk ofma-
terial losses, poisoning and explosion.
Never use or store explosive and flammable materials, e.g. petrol, thin-
ners, paints, paper etc. inside the boiler room.
To save energy and protect against scaling if the total hardness is greater than 2.5 mol/
m³, the DHW temperature may be set to a maximum of 50 °C.
If the total hardness is greater than 3.58 mol/m³, we recommend using a water treat-
ment facility in the cold water supply line for DHW heating, to prolong the maintenance
interval (descaling DHW heat exchanger).
Never use or store sprays, solvents, chlorinated cleaning agents, detergents, paints,
lacquers, adhesives, de-icing salt etc. in the vicinity of the condensing boiler. Under
unfavourable conditions, these materials may lead to corrosion in the boiler and the flue
gas system. Ducted vents routed through a roof may also contain corrosive vapours.
Please note - non-observance may cause gas leakage and can create a fire
hazard and a risk of material losses, poisoning and explosion.
Clean the casing with a damp cloth and a mild cleaning agent (without chlorine). Dry
immediately after. The components inside the gas fired condensing boiler and in its
immediate surrounding may only be cleaned by a heating contractor
Please note - only the heating contractor offers the required knowledge
and expertise!
- The user is obliged to arrange regular system maintenance, in order to ensure the
reliable and safe function of the gas fired condensing boiler.
- Your gas fired condensing boiler should be serviced annually.
- Maintenance is explicitly detailed in the installation and maintenance instructions.
- Isolate the boiler power supply before any maintenance work is carried out.
- After a service and before the gas fired condensing boiler is restarted, check that all
components which have been removed for maintenance have been properly refitted.
- We recommend you arrange a maintenance contract with an approved heating con-
tractor.
Seal the front casing tightly with screws after completing the service.
There is a risk of carbon monoxide poisoning if the flue system is
faulty.
