Lateral clearances min. 40 mm
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.
In addition, all components of the condensing boiler must be
freely accessible from the front. It must be possible to carry
out flue gas emissions tests. If minimum clearances and ac -
cessibility 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 cause 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 and chlorine or sulphur.
Such materials are contained in sprays, paints,
adhesives, solvents and cleaning agents. Under
unfavourable conditions, these may lead to
corrosion, including in the flue system.
During boiler installation, ensure that no con -
taminants (e.g. drilling dust) enter the gas boiler,
as this could lead to appliance faults.
Please
note
First determine where the appliance is to be installed.
For this, take into account the flue outlet, lateral clearances
towards walls and ceiling and any existing connections for gas,
central heating, DHW and electrics.
Operation in wet rooms
In the delivered condition and for room-sealed opera-
tion, the Wolf gas condensing boiler has IP rating IPx4D.
When installing it in wet rooms, the following conditions must
be met:
- Balanced flue operation
- Compliance with IP rating IP 4D
- 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.
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.
