Installation and
maintenance information
Installation/modications
- Your gas red condensing boiler should only be installed and modied by an appro-
ved heating contractor, as only they have the essential knowledge to carry out such
work.
- Gas components must not be modied.
- 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 retted.
- 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.
