Outdoor air supply for combustion
(optional equipment)
Dimensions for fi tting
(Figure 14)
Examples of possible connections
The appliance is dependent on indoor air (open-fl ued appliance); that means
the air required for combustion is drawn from the room where the appliance is
located. Therefore the room must be supplied with fresh air from the outside
through an air inlet. Provide an opening that is 10-15 cm in diameter in an exte-
rior wall in the room where the appliance is located. Install a protective grating
on the outside of the air inlet. In particularly exposed locations it is advisable
to provide protection against wind and rain.
If it is not possible to provide an air inlet to the outside from the room where
the appliance is located, the opening can be in an adjoining room. In this case
the adjoining room must have a permanent connection to the room where the
appliance is installed via a ventilation grid. If there are additional heating ap-
pliances in the same room, make sure that the air inlets can supply suffi cient
air for combustion for the operation of all appliances.

Air supply for combustion via pipe line through a basement room
(Figure 15)
The combustion air is preheated with this connection option, which is favo-
rable to a clean combustion. The routing in the basement room is easy to
make.
Air supply for combustion directly
from
outdoor
(Figure 16)
In a air supply directly through an outside wall, the combustion air is only
slightly preheated, which is unfavorable to a clean combustion. There is also
the danger of condensation!

An air supply from above may only be with tested chimney systems, a chimney
calculation is mandatory!
