Installation and
maintenance information
Installation/modications
- Your gas red condensing boiler should only be installed and modied by an appro-
ved heating contractor, as only they have the essential knowledge to carry out such
work.
- Gas components must not be modied.
- Never close or restrict the ventilation apertures in doors or walls when operating
the boiler in the open ue mode; only start the boiler when the ue pipe has
been fully installed.
- Only take the boiler into use when operating the device in balanced ue mode, if the
balanced ue system has been fully installed and the wind protector is not covered
up.
- Gas red 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 re hazard and a risk ofma-
terial losses, poisoning and explosion.
Never use or store explosive and ammable materials, e.g. petrol, thin-
ners, paints, paper etc. inside the boiler room.
Care
Clean the casing with a damp cloth and a mild cleaning agent (without chlorine). Dry
immediately after. The components inside the gas red condensing boiler and in its
immediate surrounding may only be cleaned by a heating contractor
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).
Wartung
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 red condensing boiler.
- Your gas red 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 red condensing boiler is restarted, check that all
components which have been removed for maintenance have been properly retted.
- We recommend you arrange a maintenance contract with an approved heating con-
tractor.
Corrosion protection
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 ue
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 re
hazard and a risk of material losses, poisoning and explosion.
Seal the front casing tightly with screws after completing the service.
There is a risk of carbon monoxide poisoning if the ue system is
faulty.
