Combustion Air Requirements
In order for the stove to perform efficiently and safely there should be an adequate air
supply into the room in which the stove is installed to provide combustion air. This is
particularly necessary in modern houses where drafts have been almost eliminated by
double glazing etc.
Under UK building regulations any appliance over 5kW MUST have a fixed
permanent air vent (see Building Regulations Approved Document J for further
information).
Calculating the vent
For new build you will need to provide 8 x 550mm
2
= 4400mm
2
free air.
Older properties will require 3 x 550mm
2
= 1650mm
2
free air.
There must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit fumes into the room. It is necessary to install a wall vent to provide the
necessary combustion air and to prevent the depletion of oxygen in the room.
The above ventilation requirement is per product which means two products cannot share
one vent.
