INSTALLATION REQUIREMENTS
1.1 CONDITIONS OF INSTALLATION
It is the law that all gas appliances are installed only by a GAS SAFE 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. B.S. 5871 Part 3 Installation of Decorative Fuel Effect Gas Fires
2. B.S. 6891 Installation of Gas Pipework
3. B.S. 5440 Parts 1 & 2 Installation of Flues and Ventilation
4. B.S. 1251 Open fire place components
5. B.S. 715 Metal flue pipes for gas appliances
6. B.S. 6461 Part 1 Installation of Chimneys and flues
7. B.S. E.N. 1858 Chinmeys Components & Concrete Flue Blocks
8. I.S. 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. It is also suitable for use with pre-cast flue blocks conforming
to B.S. E.N. 1858 and metal flue boxes conforming to BS 715. 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
leave the flue restrictor baffle (supplied) in place 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 440 mm wide, and
between 550 and 575mm 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 175mm. If the depth is less than 175mm then the chairbrick
must be removed. 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
When installing this appliance into pre-cast flues, always ensure that the
spigot restrictor baffle has been removed. This is held in place on the spigot
by 2 screws
To install the fire box in to pre-cast flue starter blocks, there must be at least
125mm 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 125mm then a fire surround with a deeper rebate to increase the depth
to at least 125mm from the mounting face of the fire. 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 125 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 12mm 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 burner. 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.

225 x 225mm (9 inch x 9 inch) brick built chimneys
175mm (7 inch) diameter lined brick or stone flue, or insulated pre-fabricated
metal flue box to B.S. 715.
When installing into 125mm (5 inch) diameter lined brick or stone flue, or
insulated pre-fabricated metal flue box to B.S. 715 and pre-cast flues the
restrictor baffle must not be fitted.
A spillage test must always be carried out to check satisfactory
clearance of flue products, regardless of the type of flue the
appliance is being fitted to.

Proceed as follows :-
a) Remove the two screws at the bottom of the control panel. See fig. 3
below
Fig. 3
b) The base of the burner unit can now be lifted, lift the two retaining
tabs on the burner brackets from the back of the firebox, allowing
the burner to be removed. See fig. 4 below
Fig. 4
c) Ensure that the hearth is protected from damage and carefully lift the
fire box into the fire opening, then slide it back into position. Check that
the fire box flange fits flush to the sealing face of the fire surround or
wall with no gaps present.

d) Whilst the fire box is still in position, decide which side the gas supply is
to enter the fire from. If concealed pipe work is required plan the pipe
run to enter the fire box through one of the openings in the sides or rear
of the fire box below the fuelbed support panel and connect to the
isolating / inlet elbow. The gas connection to the appliance should be
made to the isolating / inlet elbow using 8mm rigid tubing. There must
be no soldered joints within the firebox. See fig. 5a & 5b below for
suggested concealed pipe layouts.
Fig. 5a
Fig. 5b
Note : Before breaking into the gas supply a pressure drop test should be
carried out to establish that the existing pipework is sound.
Carefully withdraw the fire box from the opening to enable the gas supply and fire
fixing to be completed.

IMPORTANT : Sealing of the Gas Inlet Apertures
In line with current GAS SAFE regulations, it is imperative that the gas supply
inlet aperture that is utilised during the installation is sealed with the
grommet as supplied in the loose items pack. The product is manufactured
with 3 knock out gas inlets in the firebox wrap to allow a left hand, right hand or
rear gas inlet supply to the inlet elbow. Using a hammer and a blunt chisel,
remove the inlet aperture selected and then seal with the grommet supplied. To
provide access for the gas supply pipe, cut the grommet with a sharp knife.
Failure to seal the inlet apertures could lead to flame reversal, which in turn will
damage the burner and control systems of the product.
Fig. 6 below shows a correctly sealed installation.

There is a choice of methods of fixing the firebox which are provided to enable the
installer to deal with any type of installation.
The preferred method of fixing which is suitable for almost all situations is
the cable fixing method which is described in the following section in detail.
The fire may be secured using the cable method as described below, or
alternatively, in installations where the cable method is not suitable (eg. loose
masonary in rear of fire opening) the fire box can be directly secured to the fire
surround using the screws and rawlplugs provided.
To fit using the preferred cable method proceed as follows-
e) Mark out and drill 4 off No 14 (7mm) holes in the back face of the fire
opening in the positions shown below in fig. 7
Fig. 7
Fit the wallplugs provided and screw the fixing eyes securely into the rear of the
fire opening. If the clearance at the rear of the fire is at the minimum specified for
a precast flue application, it may be necessary to bend over the lower fixing eyes
after screwing them fully in to the rear of a pre-cast starter block.
f) Uncoil the two fire fixing cables and thread one end of each of the
cables through one of the two holes on each side of the flue outlet
shroud.
