chamber). Materials above the stove are far 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 (6-12mm for example) between the shield and combustible material. Gypsum
plaster and plasterboards may well be non-combustible but can structurally deteriorate (crumble)
when exposed to temperatures of greater than 50 deg C for long periods of time.
Distances from NON-combustible materials:
The stove can be recessed in a suitable sized non-combustible fireplace but a permanent free air
gap of at least 50mm must be left around the sides and top and at least 50mm at the back of the
stove to obtain reasonable heat output and for access to the stove for removal and maintenance.
A clearance of 150mm will give a better heat output and make access a lot easier.
In accordance with Building regulations all non-combustible walls closer than 400mm to the stove
should be at least 75mm thick. For practical reasons the back wall of a fireplace recess and the
hearth should be made of non-combustible material.

Hearths:
These stoves do not require a constructional hearth beneath them as they do not cause the floor
temperature to exceed 100 degrees C. Hearths must be generally level. In all instances a non-
combustible superimposed hearth extending fully underneath the stove and forming an apron of
at least 225mm at the front of the stove and 150mm on either side must 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.
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.

Commissioning and Handover
CO Alarm: Building Regulations require that whenever a new or replacement fixed solid fuel or
wood/biomass appliance is installed in a dwelling a carbon monoxide alarm must be fitted in the
same room as the appliance. Further guidance is available in BS EN50292:2002 and from the alarm
manufacturer’s instructions. Provision of an alarm must not be considered a substitute for either
installing the appliance correctly or ensuring regular servicing and maintenance of the appliance
and chimney system. It is recommended that an alarm also be fitted in other spaces where
Building regulations may not apply such as garden rooms, sheds, cabins, tents, glamping pods etc
as additional safety provision.
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.
Advise the customer not to run the stove at full output for at 3
–
4 days. Explain that the stoves
can provide much more or less output than their rated heat outputs depending upon fuels, fuel
loads used and how they are operated.
