Health and safety precautions
Special care must be taken when installing the stove such that the requirements of the He-
alth and Safety at Work Act are met.
Handling
Adequate facilities must be available for loading, unloading and site handling.
Fire Cement
Some types of fire cement are caustic and should not be allowed to come into contact
with the skin. In case of contact wash immediately with plenty of water.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the
course of installation then please seek specialist guidance and use appropriate protective
equipment.
Metal Parts
When installing or servicing this stove care should be taken to avoid the possibility of per-
sonal injury.
Note of references to the current UK regulations
In all cases the installation must comply with current Building Regulations, Local Authority
Byelaws and other specifications or regulations as they affect the installation of the stove.
It should be noted that the Building Regulations requirements may be met by adopting the
relevant recommendations given in British Standards BS 8303, BS EN 15287-1:2007 as an
alternative means to achieve an equivalent level of performance to that obtained following
the guidance given in Approved Document J.
Please note that it is a legal requirement under England and Wales Building Regulations
that the installation of the stove is either carried out under Local Authority Building Con-
trol approval or is installed by a Competent Person registered with a Government appro-
ved Competent Persons Scheme. HETAS Ltd operate such a Scheme and a listing of their
Registered Competent Persons can be found on their website at www.hetas.co.uk.
This stove must not be installed into a chimney that serves any other heating appliance.
More detailed advice about existing chimney usage
NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet
of the stove to the top of the chimney should be satisfactory. Alternatively the calculation
procedure given in EN 13384-1 may be used as the basis for deciding whether a particular
chimney design will provide sufficient draught.
The outlet from the chimney should be above the roof of the building in accordance with
the provisions of Building Regulations Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or other
faults which might allow fumes into the house. Older properties, especially, may have
chimney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Re-
medial action should be taken, if required, seeking expert advice, if necessary. If it is found
36
necessary to line the chimney then a flue liner suitable for solid fuel must be used in accor-
dance with Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been swept clean immediately
before installation of the stove. If the stove is fitted in place of an open fire then the chim-
ney 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
above 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
suitable for use as the complete chimney. The chimney and connecting fluepipe must have
a minimum 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 fireplaces or flues could ignite it. Therefore when installing the stove in the presence
of combustible 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 instructions.
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 combu-
stion are vented safely to atmosphere via the chimney terminal.
On completion of the installation and commissioning ensure that the operating instruc-
tions for the stove are left with the customer. Ensure to advise the customer on the cor-
rect 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 custo-
mer should be warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the pre-
sence 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
dwelling. 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:-
