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),
73/23/EEC (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. 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).
