Supply Of Combustion Air/Option - Contura C 556 Installation Instructions Manual

Supply of combustion air
When a stove is installed in a room, the air supply demand 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 25m 3
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.
