Siting - Wolf CGS-2-14/120L Installation Instructions Manual

Minimum clearances
We recommend observing minimum clearances to facilitate
inspection and maintenance work on the boiler. This ensures
that adequate inspection and function tests can be carried out
on the appliance.
The boiler may be installed only in rooms that
are protected from frost.
The temperature in the installation room must be between
0°C and 40°C.
The temperature in the installation room must be between 0°C
and 40°C. In addition, all components of the condensing boiler
must be freely accessible from the front. It must be possible to
carry out flue gas tests. If minimum clearances and accessibility
are not observed, Wolf may stipulate accessibility for on-site
customer service attendance.
Clearance between the boiler and combustible
materials or components is not required, as
temperatures will not exceed 85 °C at the rated
boiler heating output. However, explosive or
readily flammable materials must not be used
in the installation room as this would create a
risk of fire or explosion.
The installation room and the combustion air
supplied to the appliance must be free from
chemicals, e.g. fluorine, chlorine or sulphur.
Such materials are contained in sprays, paints,
adhesives, solvents and cleaning agents. Un-
der unfavourable conditions, these may lead
to corrosion, including in the flue gas system.
During boiler installation, ensure that no con-

taminants (e.g. drilling dust) enter the gas boiler,
note
as this could lead to appliance faults.
Operation in wet rooms
In the delivered condition and for room sealed operation, the
Wolf gas condensing boiler has IP rating IPx4D. When installing
it in wet rooms, the following conditions must be met:
- Room sealed operation
- Compliance with IP rating IPx4D
- All outgoing and incoming cables must be routed through
the strain relief cable glands and secured. Tighten the cable
glands securely to ensure that no water can enter the casing.

Fig.: Minimum clearances
First determine where the appliance is to be installed. For this,
take into account the flue gas connection, lateral clearances
towards walls and the ceiling, and any existing connections
for gas, heating, DHW and electrics.
Sound insulation: Under certain critical installation conditions
(e.g. installation on a drywall), additional measures may be
necessary to soundproof the boiler. In such conditions, use
anti-vibration rawl plugs and, if necessary, rubber mounts or
insulation strips.
