If necessary a hole must be opened up into the flue way above the fireplace in order to fit the appliance to the
flue correctly. Please consult HETAS recommended fi�ng methods if in doubt. It is
essen�al
that all connec�ons
between the stove and chimney-flue are sealed and made air�ght with sealing rope, clamping rings and/or fire
cement or heat resis�ng cement where required.
Both the chimney and flue pipe must be accessible for cleaning and if ANY parts of the chimney cannot be
reached through the stove (with baffle removed), a soot door must be fi�ed in a suitable posi�on to enable this
to be done.
In adverse weather condi�ons, downdra�s may occur causing smoke or fumes to spill into the room. If this
occurs the appliance should be shut down as much as possible by closing the air controls and the room should
be ven�lated to clear the fumes. If the problem persists seek the advice of a chimney sweep.
4.5 Fixings
Fix the stove to the back hearth using suitable non-combus�ble fixings through the base of the outer firebox. If
necessary screw the outer firebox to the back panel by fixing the top or side flamges using suitable non-
combus�ble fixings.
4.6 Material Clearances
Safety Distances from Combus�ble Surfaces:
Model
Shelf
Side (outer edge of trim)
FW5C
500mm
350mm
This appliance must be installed in a recess which must not contain any combus�ble materials. Wooden ba�ens
and plasterboard should not be used within the clearance to combus�bles.
In addi�on it is strongly recommended that any furniture or other combus�ble materials are kept at least 100cm
clear from the front of the stove.
Distances from non-combus�ble materials
To conform with Building Regula�ons the fireplace recess walls should be at least 200mm thick. If it is proposed
to instal the stove in anything other than a brick or cement block housing it will be necessary to increase the
housing size to give a minimum clearance of 200mm a�er at least three layers of “Glasroc” or similar heat proof,
insula�ng material, have been a�ached to the housing walls. The stove top and walls may reach over three
hundred degrees Celsius when opera�ng and it is possible for the flue to reach even higher temperatures and if
there is any doubt as to the ability of the housing to operate safely with the heat produced by the stove,
professional advice should be sought.
4.7 Hearths
This stove require a 125mm thick non-combus�ble construc�onal hearth beneath them to protect the building,
this can include any solid non-combus�ble floor. A non-combus�ble superimposed hearth forming an apron of
at least 225mm at the front of the stove and 150mm on either side must also be provided. The superimposed
hearth must not be less than 12mm thick and must have a clearly defined edge (change of level) to discourage
placing of any combus�ble materials on or par�ally over it.
The appliance must be installed on a floor with adequate load-bearing capacity. If the exis�ng construc�on does
not meet this requirement, suitable measures (e.g. load distribu�ng plate) should be provided to achieve it.
