Installation; Positioning - Wolf FGB-K Series Installation And Maintenance Instructions For Contractors

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 only be installed 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 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 are limited to 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. fluoride 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.
The appliance is not suitable for outdoor

installation.

The boiler is intended solely for installation
and operation in sealed unvented heating
systems.
During boiler installation, ensure that no
Please note
contaminants (e.g. drilling dust) enter the gas
boiler, as this could lead to appliance faults.
Operation in wet rooms
In the delivered condition and for balanced flue operation,
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 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.

7. Positioning

Fig: Minimum clearances
First determine where the appliance is to be installed.
For this, consider the flue outlet, the lateral clearances
towards walls and ceiling and any existing connections for
gas, central 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 a case, use
anti-vibration rawl plugs and, if necessary, rubber mounts or
insulation strips.
