Supply of combustion air
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
to be placed. The amount of combustion air used for combustion is
approximately 30 m³/h (applies with closed hatch),
Some installation alternatives are shown to the right. The air duct
connection on the stove has an external diameter of Ø100 mm.
In hot areas the duct should be insulated with 30 mm mineral wool
covered with a moisture inhibitor (aluminium tape).
It is important that the lead-in between the pipe and the wall (or floor) is
sealed using jointing compound.
A 1 m length of condensation insulated ducting for combustion air is
available as an accessory.
