Combustion air can be provided directly via a duct from outside,
or indirectly via a vent in the outer wall of the room where the
stove is placed. The amount of combustion air that is used for
combustion is approx. 20 m
3 /h.
Outside air can be connected through the floor plate or at two
different heights through the two panels in the back of the stove.
Tap out the knockout using a hammer. The air duct connector on
the stove has an external diameter of Ø64 mm.
In hot areas, the duct has to be insulated with 30 mm mineral wool
covered with a moisture barrier (plastic). It is important that the
lead-in, between the pipe and the wall (or floor), is sealed using
jointing compound. When duct routing for further than 1 m, the
pipe diameter must be increased to 100 mm and a correspondingly
larger wall vent must be selected.
A 1 m length of condensation-insulated ducting for combustion air
is available as an accessory.
