clear any soot falls which may have occurred due to the difference in combustion between the stove and the open
fireplace. If there is no existing chimney either a prefabricated block chimney in accordance with Building
Regulations Approved Document J or a twin walled insulated stainless steel flue to BS 4543 can be used. These
chimneys must be fitted in accordance with the manufacturer's instructions and Building Regulations.
A single wall metal flue pipe is suitable for connecting the stove to the chimney but is not suitable for use on the
complete chimney. The chimney and connecting flue pipe must have a minimum diameter of 150 mm, unless the
stove is an approved smoke exempt model where it may be 125 mm, and its dimension should be no less than the
size of the outlet socket of the stove.
Any bend in the chimney or connecting flue pipe should not exceed 45°. 90° bends should not be used.
If excessive draught is found in the chimney a draught stabilizer should be mounted.
Adequate provision e.g. easily accessible soot door(s) must be provided for sweeping the chimney and
connecting flue pipe.
Distance to combustible materials
Combustible materials should not be located where the heat dissipated through the walls of fireplaces and 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 Document
J and to the instructions in this manual.
Distance to combustible materials rear
Distance to combustible materials side
Distance to flammable materials/furnitures
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney, if the chimney is not
independently supported.
The Westfire WF UNIQ36 / WF UNIQ37 wood stove has been tested and is suitable to be installed on a 12 mm non
combustible plate such as Westfire 12 mm glass plates or 20 mm slate plates. Installation of all hearths should
comply in size and construction and be in accordance with the provisions of the current Building Regulations
Approved Document J.
The clearance distances to combustible material beneath, around or upon the hearth, and to the walls adjacent to
the hearth, should comply with the guidance on the separation of combustible material given in Building
Regulations Approved Document J and to the instructions in this manual.
If the stove is installed on a wooden floor it must be covered with a minimum 12 mm thick non-combustible
material, 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.
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.
