A stove top deflector heat shield is supplied with every stove to provide help for
combustible shelves or surrounds that are closer than ideal to the stove top. With
the deflector fitted a 6” combustible shelf can be maintained at minimum 125mm
(5”) from the stove top. Fitting this part is optional and it does not affect stove
operation at all.
In addition it is strongly recommended that any furniture or other combustible materials
are kept at least 900mm clear from the front of the stove.
As a guideline, materials that are in ‘line of sight’ to the stove are more likely to overheat
than materials that are not in ‘line of sight’ due to direct radiation from the stove body.
Materials above the stove are more likely to overheat than materials alongside or below.
A guideline limiting temperature for solid timber (not surface finishes) is approximately
80-85 degrees C with a normal ambient room temperature. Temperatures of
combustible materials can be substantially lowered with a simple heat shield
constructed of a non-combustible material and small air gap between the shield and
combustible material.
Distances from NON-combustible materials:
The stove can be recessed in a suitable sized non-combustible fireplace. To conform to
building regulations the fireplace recess walls should be at least 200mm thick or each
rear leaf at least 100mm thick in the case of a cavity wall at the rear. If these dimensions
are not met further protection for any combustible materials must be provided. The walls
of the fireplace recess and the hearth must be made of non-combustible material.
4.7 Hearths:
All FDC Taper inset stoves require a 125mm thick non-combustible constructional
hearth beneath them to protect the building; this can include any solid non-combustible
floor. A non-combustible 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 combustible materials on or partially
over it. Ensure the hearth is flat & level and the back panel and surround are at right
angles to the hearth.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the
existing construction does not meet this requirement, suitable measures (e.g. load
distributing plate) should be provided to achieve it.
4.8 Commissioning and Handover
A CO detector must be fitted in the same room as the stove according to current
standards or codes of practice. Advise the customer of the importance of this device and
maintaining it.
Upon completion of the installation, allow a suitable period of time for any fire cement
and mortar to dry out. A small fire may then be lit and checked to ensure the smoke and
fumes are taken from the stove up the chimney and emitted safely to atmosphere.
