ance, 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. 1289 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
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.

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 dis-
tance 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 chim
ney / flue and that the smoke can be seen issuing from the terminal /
chimney pot outside.
5

Supplied By www.heating spares.co Tel. [phone]
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 190mm. If the depth is less than 190mm then the spacer
(optional) must be used to give a minimum clearance from the rear of the fire to
the rear of the chairbrick of at least 90mm to allow sufficient space for the collec-
tion of debris which may fall down the chimney. 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 spacer (optional) must be used to increase the depth to
at least 120mm 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 120 mm to the rear of the starter
block, otherwise there will be insufficient depth. This can be reduced to 70mm if
the optional black spacer is used. 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
CFM 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 1289. In accordance with BS 1289 Part 1, 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 con-
structional 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 maxi-
mum 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.

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. If the black spacer frame is used, the
hearth projection forward from the fireplace opening will require to be 350mm.
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 combus-
tion products in the room in which the fire is operated. The following are impor-
tant 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.

d) Continue for all models
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 of the fire box below the fuelbed sup-
port 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. 5 & 6 below for sug-
gested concealed pipe layouts.
Fig. 5
Fig. 6
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.Depending on the spacer option selected, (flush fit or 2”
black spacer) 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.
If the 2” black spacer is used, 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 spacer may be removed
from the fire box and secured to the fire surround using protruding screws which
engage on to the key hole slots on the rear face of the spacer. The spacer will
then need to be sealed to the fire surround. The fire box can then be refitted to
the spacer.
To fit using the preferred cable method proceed as follows-
e) Mark out and drill 4 off No 14 (6mm) 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.
g) Position the fire carefully on the (protected) surface of the hearth and
reach into the fire opening. Thread each of the cables vertically
downwards through the pair of fixing eyes on the same side of the fire.
Thread the free end of the cables through the corresponding circular
hole on each side of the lower rear of the fire. Carefully slide the fire
box back into the fire opening and pull both cables tight.

h) Thread a tensioning screw over each of the cables and ensure that the
tensioning nut is screwed fully up against the hexagon shoulder of the
tensioning screw (this provides maximum travel for the tensioning nut).
i) Fit a screwed nipple on to each of the cables and pull hand tight up
against the tensioning screw, then secure each nipple with a flat
bladed screwdriver. See fig. 8 below
Fig. 8
j) Evenly tighten the tensioning nuts to tension both cables and pull the
fire snugly against the wall. Do not overtighten, it is only necessary to
pull the seal up against the sealing face of the wall, it does not need to
be compressed. Check that there are no gaps behind the seal.
k) With the fire securely in place, if a concealed gas connection has been
made through either of the access holes in the sides of the fire, the
holes should be closed around the pipe to prevent leakage of air
through the gap around the pipe.
l) Refit the burner. Fit the four retaining screws and check that the burner
is correctly locked into position.

m) Refit the front burner heat shield to the sides of the fire box (2 Screws)
and secure the trim to the fire using the magnets provided.
n) Before making the final gas connection, thoroughly purge the gas
supply pipework to remove all foreign matter, otherwise serious
damage may be caused to the gas control valve on the fire.
The other firebox fixing method is as follows :-
In installations where the cable method is not suitable (e.g. loose masonary in rear
of fire opening) the firebox can be secured to the fire surround using four screws
and wall plugs provided. Below (fig.9) is a diagram to indicate the hole centre
positions available on the firebox to facilitate the screw fixing to the fireplace /
surround.
