INSTALLATION REQUIREMENTS
1.1 CONDITIONS OF INSTALLATION
It is the law that all gas appliances are installed only by a Registered Installer, in
accordance with these installation instructions and the Gas Safety (Installation and
Use) Regulations 1998 as amended. Failure to install appliances correctly could
lead to prosecution. It is in your own interest and that of safety to comply with the
law.
The installation must also be in accordance with all relevant parts of the Local and
National Building Regulations where appropriate, the Building Regulations
(Scotland Consolidation) issued by the Scottish Development Department, and all
applicable requirements of the following British Standard Code of Practice.
1. BS 5871 Part 2 Installation of Inset Live Fuel Effect Gas Fires
2. BS 6891 Installation of Gas Pipework
3. BS 5440 Parts 1 & 2 Installation of Flues and Ventilation
4. BS 1251 Open fire place components
5. BS 715 / BS EN 1856-2 Metal flue pipes for gas appliances
6. BS EN 1858 Clay Flue Blocks and Terminals
7. IS 813 : 1996 Domestic Gas Installation (Republic of Ireland)
No purpose made additional ventilation is normally required for this
appliance, when installed in G.B. When Installing in I.E. please consult
document I.S. 813 : 1996 Domestic Gas Installation, which is issued by the
National Standards Authority of Ireland. If installing in Northern Ireland,
please consult local building regulations. Any purpose made ventilation
must be checked periodically to ensure that it is free from obstruction.
1.2 FLUE AND CHIMNEY SUITABILITY
This appliance is designed for use with conventional brick built or lined chimneys
and fabricated flues and metal flue boxes conforming to BS 715 / BS EN 1856-2.
All flues must conform to the following minimum dimensions.
Minimum diameter of circular flues 125 mm (Without Flue
Restrictor Fitted)
Minimum effective height of all flue types 3 metres
When fitting to conventional chimneys or 175mm flues it may be desirable to
fit the flue restrictor baffle (supplied) to reduce the flue flow and increase the
efficiency of the fire. Safe clearance of products must always be checked by
carrying out a smoke match test as described.
4
1.3 FIREPLACE / SURROUND SUITABILITY
The fire must only be installed on a hearth it must not be installed directly onto
carpet or other combustible floor materials.
The fire is suitable for fitting to non-combustible fire place surrounds and propri-
etary fire place surrounds with a temperature rating of at least 150oc.
If a heating appliance is fitted directly against a wall without the use of a fire
surround or fire place all combustible material must be removed from behind
the trim. Soft wall coverings such as blown vinyl, wall paper etc. could be
affected by the rising hot air and scorching and/or discoloration may result.
Due consideration should be made to this when installing or decorating.
1.4 SHELF POSITION
The fire may be fitted below a combustible shelf providing there is a minimum distance of 200mm above the top of the fire and the shelf does not project more than
150mm. If the shelf overhangs more than 150mm the distance between the fire
and the shelf must be increased by 15mm for every 25mm of additional overhang
over 150mm.
1.5 FLUE / CHIMNEY INSPECTION
Before commencing installation, a flue or chimney should be inspected to ensure
that all the following conditions are satisfied.
1. Check that the chimney / flue only serves one fire place and is clear of any
obstruction. Any dampers or register plates must be removed or locked in
the open position.
2. Brick/stone built chimneys or any chimney or flue which has been used for
an appliance burning fuel other than gas must be thoroughly swept. The
base of the chimney / flue must also be thoroughly cleared of debris etc.
3. Any under-floor air supply to the fire place must be completely sealed off.
4. Ensure that the inside of the chimney / flue is in good condition along it’s
length and check that there is no leakage of smoke through the structure
of the chimney during and after the smoke pellet test. With pre-cast flues
it is especially important to check the inside of the flue for extruded
cement / sealant protruding from the joints between the flue
blocks. If present, these should be removed by rodding the flue
before proceeding with the installation.
5. Using a smoke pellet, check that there is an up-draught in the
chimney / flue and that the smoke can be seen issuing from the
terminal / chimney pot outside.
5
There must be no leakage of smoke through the structure of
the chimney during or after the smoke pellet test and it is
important to check inside upstairs rooms adjacent to the chimney /
flue. Check the chimney pot / terminal and general condition of the
brickwork or masonry. If the chimney or flue is in poor condition or if
there is no up-draught do not proceed with the installation. If there is a
history of down-draught conditions with the chimney / flue, a tested and
certificated flue terminal or cowl suitable for the relevant flue type should
be considered.
6. A spillage test must always be carried out during commissioning of
the appliance.
1.6 FIRE PLACE OPENING AND CHIMNEY CATCHMENT SPACE
The front opening of the fire place must be between 330 and 430 mm wide, and
between 550 and 565mm high. If the opening exceeds these dimensions then a
surround must be constructed from suitable non-combustible material to produce a
correct size opening. Any surround must be suitably sealed to the fire place to
prevent leakage. See below in fig.1
When installing into a brick built chimney, you must ensure that there is sufficient
depth to accomodate any debris which may fall from the chimney. This depth
must be sufficient to accomodate 12 litres of volumetric space.

1.7 FITTING TO FIREPLACES WITH EXISTING CHAIRBRICKS AND
CONVENTIONAL BRICKBUILT CHIMNEYS
This appliance is suitable for use in fireplaces fitted with an existing chairbrick
without the need for removal of the chairbrick, providing the minimum depth of the
fireplace exceeds 170mm. The fireplace must be checked to ensure that no part of
the chairbrick is within 50mm of the flue outlet of the fire when installed.
1.8 FITTING TO PRE-CAST FLUE INSTALLATIONS
To install the fire box in to pre-cast flue starter blocks, there must be at least
120mm from the mounting face of the fire to the rear of the pre-cast flue
starter block to allow sufficient space for debris collection. If this dimension is
less than 120mm then the fire is not suitable. It is important to consider this depth
when choosing a fire surround as the thickness of the fire surround must be
sufficient to give a total depth of at least 120 mm to the rear of the starter
block, otherwise there will be insufficient depth. To increase this depth the fire
surround may be packed away from the wall using suitable non-combustible
board, providing the installation is correctly sealed. If in doubt about the suitability
of the fire contact BFM Europe Ltd. for advice before proceeding.
It is important to ensure that the pre-cast flue is in good condition and is free from
extruded mortar or sealant from between the flue blocks.
This appliance has been tested for use in a pre-cast flue block complying
with BS EN 1858. In accordance with BS EN 1858, pre-cast flues built with
directly plastered faces (front or rear) are not correctly installed as to ensure
proper operation with any type of gas fire. In some instances of this flue
construction, temperature cracking of surface plaster may occur through no
fault of the appliance. An air gap or some form of insulation material should
be installed to prevent normal flue temperatures from damaging wall
surfaces.
1.9 FITTING TO PRE-FABRICATED TWIN WALL METAL FLUE BOXES
The appliance may be fitted to twin wall metal flue boxes conforming to the constructional requirements of BS 715, (for example the Selkirk LFE 125 box). The
box must have a minimum flue diameter of 125mm internal and minimum internal
dimensions of 160mm deep by 580mm high by 350mm wide. There are no
maximum dimensional requirements for the box. The top face of the box must be
insulated with a minimum thickness of 50mm of non-combustible mineral wool
insulation or similar material. The flue box must stand on a non-combustible base
of minimum thickness 12mm.
8
1.10 HEARTHS
This appliance must only be installed on to a concrete or non-combustible hearth.
The hearth material must be a minimum thickness of 13mm with the top surface at
least 50mm above the floor. The hearth must be fitted symmetrically about the fire
opening and have a minimum width of 760mm and a minimum projection of
300mm forwards from the fire opening.
1.11 SPILLAGE MONITORING SYSTEM
This appliance is fitted with an atmosphere sensing spillage monitoring system in
the form of an oxygen sensing pilot. This is designed to shut the fire off in the
event of a partial or complete blockage of the flue causing a build up of
combustion products in the room in which the fire is operated. The following are
important warnings relating to this spillage monitoring system :-
1) The spillage monitoring system must not be adjusted by the installer.
2) The spillage monitoring system must not be put out of operation.
3) When the spillage monitoring system is exchanged only a complete original
manufacturers part may be fitted. It is not possible to replace individual parts on
the pilot system on this appliance, only a complete pilot assembly (including the
thermocouple) may be fitted.
