Gas fired condensing boiler CGB-...
Gas fired condensing boilers according to DIN EN 297 / DIN
3368 T5,T6,T7,T8 / DIN EN 437 / DIN EN 483 (draft)/ DIN EN
677 (draft) / DIN EN 625 and Gas Appliance Directive 90/396/
EEC (Gas Consumer Equipment), 92/42/EEC (Boiler Efficiency
Directive), 2006/95/EG (Low Voltage Directive), and 89/336/
EEC (EMC Directive), with electronic ignition and electronic
flue gas temperature monitoring, for low temperature heating
and DHW production in heating systems with flow temperatures
up to 95 °C and 3 bar design pressure according to DIN EN
12828 part 3.
The Wolf gas fired boiler is also approved for installation in
garages.
Open flue gas fired condensing boilers must
only be installed in a room which complies with
the appropriate ventilation requirements. Other-
wise there is a risk of asphyxiation and poiso-
ning. 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).
