Combustion air supply
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 if the room is double-glazed
or a flue draught stabiliser is operating in the same room as the appliance. The provision of air supply to the
stove must be in accordance with current Building Regulations Approved Document J. An opening window is not
appropriate for this purpose.
Air inlets must be positioned in such a way that they cannot be blocked. An air inlet may be a vent (the vent must
be open and the capacity of the vent sufficient when the stove is lit) or a fresh air system linked to the stove.
The Westfire WF UNIQ26 / WF UNIQ27 / WF UNIQ28 are available with a closed air supply collar (additional item)
that enables the stove to take combustion air directly from outside with a 100 mm pipe from the stove.
There are no European rules regarding the minimum distance to non-flammable walls. Westfire recommend
leaving a gap of at least 10 cm behind and to the sides of the stove.
Westfire insulated chambers
The Westfire WF UNIQ26 / WF UNIQ27 / WF UNIQ28 wood burning stoves are lined with heat deflection panels and
baffles. These panels are designed to ensure the maximum efficiency and are an integral part of the clean burn
process of the stove. The baffles should not be removed apart from when cleaning the stove. Any defective panels
should be replaced.
Connection to chimney
WF UNIQ26 / WF UNIQ27 / WF UNIQ28 wood stoves have both a rear and top flue connector that allows connection
to either a masonry chimney or a prefabricated factory made insulated metal chimney in accordance with the
instructions of "Chimney Connection" given in the instruction booklet at page 9.
