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 approximately 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.
Through the external wall.
Indirect air supply through the external wall.
Through floor and foundation slab.
Through floor and wall-and-cavity
foundation.
In the back and floor plates there are
knockouts that must be removed to insert
pipes or for air supply if the stove is
equipped with a lower hatch and/or fan
(accessory).
Installation variants
Leave a 40 mm gap between
the condensation insulation
and the bottom of the stove.
