sary to line the chimney then a flue liner suitable for solid fuel must be used in accordance
with Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been swept clean immediately be-
fore installation of the stove. If the stove is fitted in place of an open fire then the chimney
should be swept one month after installation to clear any soot falls which may have occurred
due to the difference in combustion between the stove and the open fire.
If there is no existing chimney then any new system must be to the designation described abo-
ve and in accordance with Building Regulations Approved Document J.
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not sui-
table for use as the complete chimney. The chimney and connecting fluepipe must have a mi-
nimum diameter of 150 mm and its dimension should be not less than the size of the outlet
socket of the stove.
Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not
be used.
Combustible material should not be located where the heat dissipating through the walls of fi-
replaces or flues could ignite it. Therefore when installing the stove in the presence of combu-
stible materials due account must be taken of the guidance on the separation of combustible
material given in Building Regulations Approved Document J and also in these stove instruc-
tions.
If it is found that there is excessive draught in the chimney then a draught stabiliser should be
fitted. Fitting of a draught stabiliser will affect the requirement for the permanent air supply
into the room in which the stove is fitted in accordance with Approved Document J (see also
combustion air supply).
Commissioning and handover
Ensure all parts are fitted in accordance with the instructions.
On completion of the installation allow a suitable period of time for any fire cement and mortar
to dry out, before lighting the stove. Once the stove is under fire check all seals for soundness
and check that the flue is functioning correctly and that all products of combustion are vented
safely to atmosphere via the chimney terminal.
On completion of the installation and commissioning ensure that the operating instructions for
the stove are left with the customer. Ensure to advise the customer on the correct use of the
appliance and warn them to use only the recommended fuel for the stove.
Advise the user what to do should smoke or fumes be emitted from the stove. The customer
should be warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of
children, aged and/or infirm persons.
Warning note on fume emission
Properly installed, operated and maintained this appliance will not emit fumes into the dwel-
ling. Occasional fumes from de-ashing and re-fuelling may occur. However, persistent fume
emission is potentially dangerous and must not be tolerated. If fume emission does persist,
the following immediate actions should be taken:-
