and fabricated flues 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.

1.3 FIREPLACE / SURROUND SUITABILITY
The fire must must not be installed directly onto carpet or other combustible
floor materials. 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 150 degrees celcius
(Class “O”). If a heating appliance is fitted directly against a wall combustible
material must be removed from behind it. 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.
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. 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
1.6.1 Fireplace Opening
The front opening of the fire place must be between 400mm and 450mm wide,
between 550mm and 580mm high and minimum depth in accordance with BS
5871-2 and as detailed overpage. 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 figure 2.
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 in a conventional
brick built chimney in accordance with BS 5871-2.

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
2.2.14 Uncoil the two fire fixing cables and thread one end of each of the
cables through one of the two cable holes on each side of the rear
brackets on the firebox
2.2.15 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.
2.2.16 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).
2.2.17 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
screwdriver.
2.2.18 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.
2.2.19 Refit the burner in reverse order to which it was removed.
2.2.20 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.
