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
stabilizer should be fitted. Fitting of a draught stabilizer 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). Adequate provision
e.g. easily accessible soot door or doors must be provided for sweeping the chimney and connecting fluepipe where it is not
intended for the chimney to be swept through the appliance.
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is not independently supported.
The weight of the stove is indicated in the brochure. The stove should preferably be installed on a non-combustible hearth of a size
and construction that is in accordance with the provisions of the current Building Regulations Approved Document J.
The clearance distances to combustible material beneath, surrounding or upon the hearth and walls adjacent to the hearth should
comply with the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in
these stove instructions. If the stove is to be installed on a combustible floor surface, it must be covered with a non-combustible
material at least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of the
stove and 15 cm to each side measuring from the door of the combustion chamber.
Combustion air supply
In order for the stove to perform efficiently and safely there must be an adequate air supply into the room in which the stove is
installed to provide combustion air. The provision of air supply to the stove must be in accordance with current Building Regulations
Approved Document J. An opening window is not appropriate for this purpose.
Connection to chimney
Stoves may have a choice of either a rear or top flue gas connector that allows connection to either a masonry chimney or a
prefabricated factory made insulated metal chimney in accordance with their instructions. In some cases it may be necessary to fit
an adaptor to increase the diameter of the flue to the minimum required 150 mm section of the chimney or liner.
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.
READ THE INSTRUCTION BOOK AND THESE INSTRUCTIONS CAREFULLY BEFORE USING THE STOVE WARNING NOTE
Properly installed, operated and maintained this stove 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, then the following immediate action should be taken:
(a) Open doors and windows to ventilate the room and then leave the premises.
(b) Let the fire go out.
(c) Check for flue or chimney blockage and clean if required
(d) Do not attempt to relight the fire until the cause of the fume emission has been identified and corrected. If
necessary seek expert advice.
The most common cause of fume emission is flueway or chimney blockage. For your own safety these must be kept clean at all
times.
IMPORTANT NOTES
General
Before lighting the stove check with the installer that the installation work and commissioning checks described above have been
carried out correctly and that the chimney has been swept clean, is sound and free from any obstructions. As part of the stoves’
commissioning and handover the installer should have shown you how to operate the stove correctly.
CO Alarm
Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm sounds unexpectedly, follow the
instructions given under “Warning Note” above.
Use of fireguard
When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be used to prevent
accidental contact with the stove. The fireguard should be manufactured in accordance with BS 8423:2002 (Replaces BS 6539).
Chimney cleaning
The chimney should be swept at least twice a year. It is important that the flue connection and chimney are swept prior to lighting
up after a prolonged shutdown period. If the stove is fitted in place of an open fire then the chimney will require sweeping after a
month of continuous operation. This is a precaution to ensure that any “softer” deposits left from the open fire usage have not been
loosened by the higher flue temperatures generated by the closed stove. In situations where it is not possible to sweep through the
stove the installer will have provided alternative means, such as a soot door. After sweeping the chimney the stove flue outlet and
the flue pipe connecting the stove to the chimney must be cleaned with a flue brush.
Periods of Prolonged Non-Use
If the stove is to be left unused for a prolonged period of time then it should be given a thorough
clean to remove ash and unburned fuel residues. To enable a good flow of air through the appliance
to reduce condensation and subsequent damage, leave the air controls fully open.
