SUPPLY AIR/ACCESSORY
Supply of combustion air
When a stove is installed in a room, the demand for air supply to
the room increases. Air can be provided indirectly via a vent in
the outer wall or via a duct from the outside that is connected to
the connector on the underneath of the stove. The amount of air
needed for combustion is approx. 25m
3
/h.
The connector has an external diameter of 67 mm. When duct
routing further than 1 m the pipe diameter must be increased to
100 mm and a correspondingly larger wall vent must be selected.
In hot areas the duct should be insulated with 30 mm mineral wool
covered with a moisture inhibitor (plastic). 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.
Indirect air supply through the external wall.
Through floor and foundation slab.
Through floor and wall-and-cavity foundation.
There is a detachable cover on the reverse of
the pillar foot which is removed when installing
combustion air connection.
Installation variants
Leave a 40 mm gap between
the condensation insulation
and the bottom of the stove.
