Standards And Regulations - Wolf CGB-75 Assembly And Operating Instructions Manual

Gas condensing boiler CGB-...
Gas condensing boiler in accordance with EN 297 / EN 437 /
EN 483 / EN 677 / EN 625/pr EN 13203 and EU Directive
90/396/EEC (Gas Consumer Equipment), 92/42/EEC
(Efficiency guideline), 2006/95/EU (Low Voltage Directive)
and 2004/108/EU (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 6 bar permissible operating
pressure in accordance with EN 12 828. The Wolf gas
condensing boiler is also approved for installation in garages.
Open flue gas condensing boilers must only
be installed in a room which complies with the
appropriate ventilation requirements. Otherwise
there is a risk of asphyxiation or poisoning.
Read these installation and maintenance
instructions before installing the boiler. Also
take the technical engineering information into
consideration.
Exclusively propane in accordance with DIN
51 622 is to be used for operation with LPG,
as otherwise there is a danger of malfunctions
occurring with regard to the start-up behaviour
and the operation of the wall mounted gas boiler,
whereby there is a danger of damage to the
appliance and personal injuries.
A poorly vented LPG tank may lead to ignition
problems. In this case consult the LPG tank
filling company.
To protect against limescale formation, the hot water
temperature may be set to maximally 50 °C from a total
hardness of 15 °dH (2.5 mol/m³). This corresponds to
a maximum hot water rotary knob setting of 6 without
accessory regulator. From a total hardness of more than
20 °dH the use of water treatment in the cold water supply
pipe is always required for the heating of potable water in
order to extend the maintenance intervals.
Neglecting this can lead to premature formation of
limescale in the appliance and to limited hot water comfort.
The local conditions should always be checked by the
responsible tradesman.
