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 F UE AND CHIMNEY SUITABI ITY
This appliance is designed for use with conventional brick built or lined chimneys
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.
4

1.3 FIREP ACE / SURROUND SUITABI ITY
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 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 SHE F 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 F UE / 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 P ACE OPENING AND CHIMNEY CATCHMENT SPACE
The front opening of the fire place must be between 550 and 565mm wide, and
between 720 and 730mm 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 in a conventional
brick built chimney.

1.10 WA / HEARTH MOUNTING
This appliance must be fitted on a flat, non-combustible base of minimum
thickness 12mm. In addition, a non-combustible hearth or physical barrier should
be provided in front of the fire.
With “hole in the wall” type installations, where it may be desirable not to fit a
hearth panel or physical barrier, the product may be installed in accordance with
Document J of the building regulations so that every part of the flame or
incandescent material is at least 225mm above the floor level. For the customers
safety, and in accordance with BS 5871-2, the fitting of a hearth panel or physical
barrier should be carried out. Should this advice not be followed however, please
give consideration to the safety of the occupants in the room to which the
appliance is installed.
Any hearth panel or physical barrier that is fitted should project a mnimum of

1.10 SPI AGE 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 combus-
tion 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.

13

Continue as follows for all models :-
h) 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. 9 & 10 below for
suggested concealed pipe layouts.
Fig. 9
Fig. 10
Note : Before breaking into the gas supply a pressure drop test should be
carried out to establish that the existing pipework is sound.

i) Carefully withdraw the fire box from the opening to enable the gas
supply and fire fixing to be completed.
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 screw fixings (not provided).
To fit using the preferred cable method proceed as follows-
j) 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. 11
Fig. 11
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.
k) 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.
l) 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.
m) 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).
n) 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. 12 below
Fig. 12
o) 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.
p) With the fire securely in place, if a concealed gas connection has been
made through either of the access holes in the sides or rear of the fire,
the holes should be closed around the pipe to prevent leakage of air
through the gap around the pipe.
q) Refit the burner. Fit the 7 off retaining screws and check that the
burner is correctly locked into position, then re-fit the ceramic support
panel via 4 off screws.
r) 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.
16

The other firebox fixing method is as follows :-
s) 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 (not provided). Below (Fig.
13) is a diagram to indicate the hole centre positions available on the
firebox to facilitate the screw fixing to the fireplace / surround.
Fig. 13
2.3 FITTING THE BATTERIES TO THE RECEIVER UNIT & HANDSET
a) 4 off AA 1.5V batteries (found in the loose items pack) are to be fitted to
the battery holder located on the base of the fire below the combustion
chamber.
b) To remove the receiver unit, slide the unit forwards from it’s retaining
bracket.
c) Slide off the cover from the reciever unit.
d) Fit the 4 off AA batteries to the unit, then re-fit the cover.
e) Replace the receiver into it’s retaining bracket at the base of the fire.
f) Fit the 1 off 9V battery to the handset by removing the rear cover,
connecting the battery then replacing the cover.

2.4 GAS TIGHTNESS AND IN ET PRESSURE
a) Remove the pressure test point screw from the inlet elbow and fit a
manometer.
b) Turn on the main gas supply and carry out a gas tightness test.
c) Depress both the round buttons on the handset. The fire will then
commence its ignition sequence and will light to high. See section 3.2
for full details of the operating method for the fire.
d) Check that the gas pressure is 20.0 mbar (+/- 1.0mbar) 8.0 in w.g.(+/-
0.4 in w.g.) for G20 (NG) models or 37.0 mbar (+/- 1.0mbar) 8.0 in
w.g.(+/- 0.4 in w.g.) for G31 ( PG) models.
e) Turn off the fire, remove the manometer and refit the pressure test point
screw. Check the pressure test point screw for gas tightness with the
appliance turned on using a suitable leak detection fluid or detector.
