Installation
Gas fittings on the gas burner may be pressure
tested to 150 mbar. Higher pressure may dama
-
ge the gas burner fitting, resulting in a risk of
explosion, asphyxiation or poisoning.
Close the gas shut-off valve on the gas fired
boiler to pressure test the gas pipe.
Mount the gas ball valve in an easily accessible
place.
Connection of a 200 litre Wolf DHW cylinder or third
party cylinder
Connect the DHW flow and return with a three-way diverter
valve or the return of the gas fired boiler. Use a DHW sensor
from the Wolf accessory range when connecting a DHW cy-
linder made by third parties. A detailed description is included
with the connection set (accessories).

SEM or third party cylinder (accessories)
Gas connection
Laying the gas pipe as well as gas connections
must only be carried out by a licensed gas fitter.
Close the gas shut-off valve on the gas fired boiler
to pressure test the gas pipe.
Clean all residues from the heating pipework and the
gas pipe prior to connecting the boiler, particularly
in older systems.
Prior to commissioning, test all pipe and other gas
connections for soundness.
Inappropriate installation or using unsuitable com-
ponents or assemblies may lead to gas escaping,
which results in a risk of poisoning and explosion.
Install a gas shut-off valve with fire protection in
the gas supply line upstream of the Wolf gas fired
boiler. Otherwise explosions may occur during a fire.
Size the gas supply line in accordance with current
regulations.
