On Finished Walls - Wolf CGG-1K-24 Installation And Operating Instructions Manual

Gas connection
Laying the gas pipe as well as making the gas
connections must only be carried out by a licensed
gas fitter. Close the gas ball valve on the gas fired
combi boiler to pressure test the gas pipe.
Remove all residues from the heating pipework and
the gas pipe prior to connecting the gas fired boiler,
particularly in older systems.
Prior to commissioning, test all pipe and gas
connections for leaks.
Inappropriate installation or using unsuitable
components or assemblies may lead to gas
escaping, which results in a risk of poisoning and
explosion.
The gas valve can be subjected to a maximum
pressure of 150 mbar. Higher pressure may
damage the gas valve, resulting in a risk of
explosion, asphyxiation or poisoning. Close the
gas ball valve on the gas fired boiler to pressure
test the gas pipe.
Hydraulic connections
- Wolf connection sets (accessories) are available for
installation on finished and unfinished walls. The connection
pipes are Cu 18x1.
Cold water and DHW connection
For the cold water and DHW connection, we recommend the
installation in accordance with DIN 1988.
Install a tested and certified pressure reducer,
if the cold water supply pressure is above the
maximum permissible operating pressure of 10 bar.
Otherwise water could escape resulting in a risk
of flooding.
