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. Special attention
should be taken in newer build properties where the design air permeability is less than 5m3/h.m2. Approved Document J gives more information on this.
An opening window is not appropriate for this purpose.
The fitting of an external air kit direct to outside air must not be considered substitute for installing the appliance with a permanently open air
vent in compliance with ventilation requirements stated in Approved Document J. Please reference ADJ for further guidance.
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. All joints in the connection between the stove and the chimney must be made gastight using
fire cement and where necessary fire-proof rope infill. Means should be made for sweeping the entire length of the flue, be that through the appliance or
by suitable sweeping hatch in the flue.
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 (Repla-
ces BS 6539) in the presence of children, aged and/or infirm persons.
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.
Air Controls
Manually operated air control can be managed by adjusting the air control
valve to increase/decrease the air flow to the stove.
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.
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.
Extractor fan
There must not be an extractor fan fitted in the same room as the stove as
this can cause the stove to emit smoke and fumes into the room.
Aerosol sprays
Do not use an aerosol spray on or near the stove when it is alight.
Use of operating tools
Always use the operating tools provided when handling parts likely to be hot
when the stove is in use.
Chimney Fires
If the chimney is thoroughly and regularly swept, chimney fires should not
occur. However, if a chimney fire does occur turn off the stove immediately
and isolate the mains electricity supply (if applicable), and tightly close the
doors of the stove. This should cause the chimney fire to go out. If the
chimney fire does not go out when the above action is taken then the fire
brigade should be called immediately. Do not relight the stove until the
chimney and flueway have been cleaned and examined by a professional.
Permanent air vent
The stove requires a permanent and adequate air supply in order for it
to operate safely and efficiently. In accordance with current Building
Regulations the installer may have fitted a permanent air supply vent into
the room in which the stove is installed to provide combustion air. This air
vent should not under any circumstances be shut off or sealed.
