Positioning - Wolf CGB-11 Installation Instructions Manual

General notes
The CG... gas condensing centre for mounting on the wall is
delivered fully assembled with a power cable for the socket.
A clearance of 40 mm to the side and 400 mm to the ceiling is
recommended to enable inspection and maintenance work to
be carried out on the appliance, otherwise adequate inspection
and function tests on components cannot be ensured during
maintenance. The drain hoses must be secured with the fixing
plate above the drain outlet (siphon). The drain should be able
to be inspected
The gas fired boiler may only be installed in
rooms which are protected from frost.
Furthermore, all gas boiler components must be freely acces-
sible from the front, and flue gas measurements must be able
to be taken. If minimum dimensions and accessibility are not
maintained/given, Wolf may require accessibility to be provided
during a service visit.
Clearance between the boiler and combustible
materials or components is not required, as
temperatures are limited to 85 °C at the rated
boiler output. However, explosive and easily
combustible materials must not be used in the
boiler room; these would create a risk of fire or
explosion.
During the boiler installation, ensure that no
NB
contaminants (e.g. drilling swarf) enter the gas
fired boiler, otherwise faults may result. Use the
enclosed polystyrene cover.
First determine where the appliance is to be installed.
Consider the flue gas outlet, the lateral clearances towards
walls and ceilings, and any existing connections for gas, central
heating, DHW and electrics.

The installation room and the combustion air
supplied to the appliance must be free from
chemicals, e.g. fluoride and chlorine or sulphur.
Such materials are contained in sprays, paints,
adhesives, solvents and cleaning agents. These
may cause corrosion, even in the flue system.
The combustion air supplied to the boiler must
be free from chemicals, e.g. fluoride, chlorine or
sulphur. Such materials are contained in sprays,
solvents and cleaning agents. Under the most un-
favourable conditions, these may lead to corrosion,
even in the flue gas system.
