First determine where the appliance is to be installed.
For this, consider the ue outlet, the lateral clearances
towards walls and ceiling and any existing connections for
gas, central heating, DHW and electrics.
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 ue gas emissions tests. If minimum clearances
and accessibility are not observed, Wolf may stipulate
accessibility for on-site customer service attendance.
Operation in wet rooms
In the delivered condition and for balanced ue operation,
the Wolf gas condensing boiler has IP rating IPx4D.
When installing it in wet rooms, the following conditions must
be met:
- Balanced ue 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.
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.
The installation room and the combustion air
supplied to the appliance must be free from
chemicals,e.g.uoride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uesystem.
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ammablematerialsmustnotbeused
in the installation room as this would cause a
riskofreorexplosion.
During boiler installation, ensure that no
contaminants (e.g. drilling dust) enter the gas
boiler, as this could lead to appliance faults.

7. Positioning
The appliance is not suitable for outdoor
installation.
The boiler is intended solely for installation
and operation in sealed unvented heating
systems.
