Material Clearances
The stove can be recessed in a suitable sized fireplace but a permanent free air gap of at
least 150mm must be left around the sides and top and at least 50mm at the back of the
stove to obtain maximum heat output and for access to the rear of the stove.
All non-combustible walls closer than 400mm to the stove should be at least 75mm thick.
In all instances the back wall of the fireplace recess and the hearth should be made of
non-combustible material. Allow an apron of at least 300mm at the front of the stove and
150mm on either side. The hearth on which the stove is to be placed should not be less
than 125mm thick and should be in accordance with the current building regulations.
Care should be taken to level the stove using the adjusting screws in the feet.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the
existing construction does not meet this prerequisite, suitable measures (e.g. load
disturbing plate) should be taken to achieve it.

Commissioning and Handover
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. Do not
run the stove at full output for at least 3 – 4 days.
On completion of the installation and commissioning, ensure that the operating
instructions and operating tools for the stove are left with the customer. Ensure to advise
the customer on the correct use of the appliance with the fuels likely to be used on the
stove and warn them to use only the recommended fuels for the stove.
Advise the user on what to do should smoke or fumes be emitted from the stove. The user
should use a suitable fireguard in the presence of children, aged and/or infirm persons.
