1.2 FLUE AND CHI NEY 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.
inimum diameter of circular flues 125 mm (Without Flue
Restrictor Fitted)
inimum effective height of all flue types 4 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. This product is not suitable
for pre-cast flue’s.
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 proprietary fire place surrounds with a
temperature rating of at least 150oc. (Class “O”)
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 / CHI NEY 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 securely
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.
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.
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.
5

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 CHI NEY CATCH ENT SPACE
The front opening of the fire place must be between 400 and 450 mm wide, and
between 550 and 570mm 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.

Continue for all models as follows :-
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. 11
& 12 below for suggested concealed pipe layouts.
Fig. 11

I PORTANT : Sealing of the Gas Unused Gas Pipe Inlet Apertures
In line with current regulations, it is imperative that the gas supply inlet aper-
tures that are not utilised during the installation are sealed with the foil tape
as supplied. Failure to seal these inlet apertures could lead to flame
reversal, which in turn will damage the burner and control systems of the product.
Fig. 13 below shows a correctly sealed 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.
To fit using the preferred cable method proceed as follows-
h) 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. 14.
Fig. 14
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.
i) 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.
j) 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.
k) 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).
l) 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. 15 overpage.

m) 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.
n) 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.
o) Refit the burner. Fit the four retaining screws on manual and slide
control models or two screws on Remote control models and check that
the burner is correctly locked into position. On slide control models refit
the control cable To do this, firstly locate the nipple on one end of the
cable into recess in operating arm and then secure the front part of the
operating arm back onto the rear of the operating arm with the retained
screw.
This should not be overtightened. Move the control lever fully
downwards and check that the left hand micro-switch operates the
igniter and that the control valve spindle is fully depressed. Move the
control lever upwards to the “off” position and check that the right hand
(cut-off) micro-switch operates. Check that the control lever operates
smoothly and safely.
NOTE : The cable is factory set, and therefore should need no adjustment
p) 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.
17

q) 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.16) is a diagram to indicate the hole centre
positions available on the firebox to facilitate the screw fixing to the fireplace /
surround.
