Fig.: Wolf gas fired condensing boiler
Open flue gas fired condensing boilers
must only be installed in a room which
complies with the appropriate ventilation
requirements. Otherwise there is a risk of
asphyxiation and poisoning. Read these
installation and maintenance instructions
before installing the boiler. Also take the
Technical Guide into consideration.
Poorly vented LPG tanks can lead to ignition
problems. In such cases, contact your local
LPG supplier.
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
treatment facility in the cold water supply
line for DHW heating, to prolong the
maintenance interval (descaling DHW heat
exchanger).
