distance to Combustible materials
Combustible materials should not be located where the heat dissipating through the walls of fireplaces or flues
could ignite it. Therefore when installing the stove in the presence of combustible materials due account must be
taken of the guidance on the separation of combustible material given in Building Regulations Approved Docu-
ment J and also in these stove instructions.
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is not inde-
pendently supported.
The WESTFIRE WF UNIQ 23 wood stove has been tested and is suitable to be installed on a 12mm non combus-
tible plate such as Westfire 12mm glass plates or 20mm slate plates. Installation of all hearths should comply in
size and construction so that it is in accordance with the provisions of the current Building Regulations Approved
Document J. The clearance distances to combustible material beneath, surrounding or upon the hearth and walls
adjacent to the hearth should comply with the guidance on the separation of combustible material given in Build-
ing Regulations Approved Document J and also in these stove instructions.
If the stove is to be installed on a wooden floor, it must be covered with a non-combustible material at least
12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of the
stove and 15 cm to each side measuring from the door of the combustion chamber.
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 UNIQ 23 can be fitted as an option with a closed air supply collar; this enables the stove to take
combustion air (primary, secondary and tertiary) directly from outside via 100mm pipe from the stove.
There are no European rules regarding the minimum distance to non-flammable walls, Westfire recommend leav-
ing a gap of at least 10 cm behind and to sides of stove.
