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 20m
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.
Through the external wall.
Indirect air supply through the external wall.
Through floor and foundation slab.
Through floor and wall-and-cavity foundation.
Installation variants
Leave a 40 mm gap between
the condensation insulation
and the bottom of the stove.
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.
