Installation instructions
• Combustion air from the living-room:
When using the appliance, please ensure there is a suffi cient supply of fresh air: use
a grate with a minimum net opening in the outer wall of 150 cm
2
.
When necessary, the combustion air inlet Ø125 mm at the underside of the appliance
may be used. Through the hollow space, underneath the appliance, and a grate in
the chimney breast, combustion air can be supplied from the living room.
Make sure that the ventilation supply is open; this is particularly important with
today’s airtight dwellings.
If the dwelling has mechanical ventilation that creates under pressure in the room
where the appliance is located, it is necessary to fi t a fl ue gas fan.
The type of fl ue gas fan is dependent on the capacity of the mechanical ventilation
system. Always consult your fi tter about this.
In dwellings with an operating extractor hood, this should be turned to the lowest
setting or turned off altogether. If the extractor hood remains in use, additional
ventilation must be provided in compensation. This will not only avoid poor
combustion, but will also prevent fl ue gases being sucked from the appliance into
the room.
Should creating an extra ventilation opening prove insuffi cient, it is then necessary
to fi t a fl ue gas fan.
• Combustion air directly from outside:
The appliance now has a completely closed combustion system, which allows it to
operate independently of the surrounding air in the room where the appliance is
located.
If desired the air pipes can be fi tted with a control valve. In this case the valve
location must be visible from the outside. It is strongly advised to provide a direct
combustion air-supply if the appliance is supplied with a convection fan set.
- Appliance
with
substructure air-box:
Use one of the many combustion air supply connections Ø125 mm (external)
of the air-box.
Fit a rigid or fl exible pipe measuring Ø125 mm between this air supply connection
and the “outside air supply opening in the wall/fl oor”.
- Appliance
with
substructure fan box (convection fan):
Use the Ø125 mm (external) combustion air supply connection at the left of right
front side of the fan box.
Fit a rigid or fl exible pipe measuring Ø125 mm between this air supply connection
and the “outside air supply opening in the wall/fl oor”.
