INSTALLATION NOTES
In your own interest and for safety, in the United Kingdom, it is the law that all gas appliances are installed by competent persons in
accordance with the current edition of the Gas Safety (Installation & Use) Regulations and Amendments. Failure to install the appliance
correctly could lead to prosecution. The Confederation for the Registration of Gas Installers (CORGI) requires its members to work to
recognised standards.
This product uses fuel effect pieces, burner compartment walls and gaskets containing Refractory Ceramic Fibres (RCF), which are man-made
vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory tract. Consequently, it
makes sense to take care when handling these articles to ensure that the release of dust is kept to a minimum. To ensure that the release of fibres
from these RCF articles is kept to a minimum, during installation and servicing we recommend that you use a HEPA filtered vacuum to remove
any dust and soot accumulated in and around the fire before and after working on the fire. When replacing these articles we recommend that the
replaced items are not broken up, but are sealed within a heavy duty polythene bag, clearly labelled as RCF waste. This is not classified as
“hazardous waste” and may be disposed of at a tipping site licensed for the disposal of industrial waste. Protective clothing is not required when
handling these articles, but we recommend you follow the normal hygiene rules of not smoking, eating or drinking in the work area and always
wash your hands before eating or drinking.
This appliance does not contain any component manufactured from asbestos or asbestos related products.
The appliance data label is on the control plate below the right side of the burner tray. It is visible when the bottom front cover is removed.
The installation must be in accordance with these instructions.
In the United Kingdom the installation must also be in accordance with:
a) All the relevant parts of local regulations.
b) The Building Regulations issued by the Department of the Environment or the Building Standards (Scotland) (Consolidation)
Regulations issued by the Scottish Development Department.
c) All relevant codes of practice.
d) The relevant parts of the current editions of the following British Standards:-

a) The current editions of:-
IS 813
b) All relevant national and local rules in force.
If the appliance is intended to be installed to a chimney, which was previously used for solid fuel, the flue must be swept clean prior to
installation. All flues should be inspected for soundness and freedom from blockages.
The minimum effective height of the chimney or flue must be 3m (10ft) from the hearth to the point of termination of the flue.
The chimney or flue must have any damper or restrictor removed, or permanently secured in the fully open position.
The flue must not be used for any other appliance or application.
If the fireplace opening is of underfloor draught type, it must be sealed to stop any draughts.
A fireguard complying with BS6539 or BS6778 should be fitted for the protection of young children, the elderly, or the infirm.
In the United Kingdom (GB) no special ventilation bricks or vents are required in the room for this appliance.However, any requirement
relating to other appliances which may be in the same room must be taken into consideration.
In the Republic of Ireland (IE), permanent ventilation must comply with the regulations currently in force.
An extractor fan may only be used in the same room as this appliance, or in any area from which ventilation for the appliance is taken, if it
does not affect the safe performance of the appliance. Note the spillage test requirements detailed further on in this manual. If the fan is
likely to affect the appliance, the appliance must not be installed unless the fan is permanently disconnected.
The appliance is fitted with an A.S.D (Atmosphere sensing device). If the appliance closes down after a period of operation for no apparent
reason, the consumer should be informed to stop using the appliance until the installation and appliance have been thoroughly checked.
The A.S.D will shut the appliance down if an unacceptable amount of harmful products of combustion accumulate. Under no circumstances

GENERAL INSTALLATION REQUIREMENTS
This appliance is not suitable for installation in a room or internal space containing a bath or shower or where steam is regularly present or
in a private garage.
This appliance is suitable for the following: -
1. A masonry chimney with a minimum diameter of 175mm (7”) free from any obstruction, and with any damper or restrictor plate in the
chimney removed or secured, and having a minimum effective flue height of 3m (10ft). Note the relevant flat surface area requirement
(Figure 1). A masonry chimney having a correctly installed flue liner to BS715 and with a minimum flue diameter of 125mm is also
acceptable. Chair brick removal may not be required providing at least 50mm clearance is available from the flue outlet to any
fireplace component. The appliance is designed to cater for low lintel installations (min height 505mm) providing a minimum distance
of 25mm is maintained between the lintel and the front face of the fireplace (i.e. 25mm rebated fire surround).
2. To a fireplace that has a precast concrete or clay flue block system conforming to BS1289. The appliance is suitable for installations
conforming to older versions of BS1289 as well as the current edition. The flue blocks must have a minimum width not less than 63mm
and a cross-sectional area not less than 13,000mm2.Older editions of BS1289 required a cross-sectional area of 13,000mm2. The
current revision of the standard requires 16,500mm2. This appliance is suitable in both cases. The total depth of the opening measured
from the finished front of the fireplace (Including plaster, surround etc.) must be not less than 118mm (Figure 2).
The current version of BS1289 recommends that there should be an air space or insulation between the flue blocks and the plaster
because heat transfer may cause cracking on directly plastered flues. However, generally this appliance is suitable for installations
under all circumstances unless there is a history of cracking problems. Remember that faults such as cracking may be caused by poorly
built and restrictive flues, e.g. mortar extrusions, too many bends, flue heights below three metres, restrictive terminations, etc.
3. A
sheet metal flue system conforming with BS4543 or BS715, the flue
diameter being a minimum of 125mm (5”) (see Figure 3) with a
minimum internal depth of 150mm. Incombustible mineral wool
insulation of not less than 50mm thickness must be applied to the top
surface of the system firebox, as shown in figure 3.

Fire Surround: This appliance may be installed with a surround
with a minimum approved temperature rating of 150 degrees. The fire
surround must be sealed to the wall.
Hearth Requirements: The appliance must be mounted on a non-
combustible hearth in accordance with Figure 4. The hearth material
must have a minimum thickness of 12.5mm (1/2”). The periphery of
the hearth (or fender) should be at least 50mm above floor level to
discourage the placing of carpets or rugs over it.
INSTALLATION AND COMMISSIONING INSTRUCTIONS
PLEASE READ CAREFULLY BEFORE STARTING WORK
FIREPLACE, FLUE AND VENTILATION DETAILS
Read the important installation notes on the previous pages before proceeding with the installation of your fire. Only when you have
complied with all the requirements should you proceed any further. Note the hearth requirements.
The burner is produced from a soft ceramic material and should be handled carefully.
The burner tray assembly has been tested before it leaves the factory and is in perfect working order.
Remove any transit tape and packing and inspect for any evidence of mishandling which might affect the performance. Each unit is flame
tested before it leaves the factory and as a result there may be slight discoloration around the burner ports. There may also be slight
thermal cracking across the burner surface that is perfectly normal and is not detrimental to performance.
8mm (5/16) Bundy or semi-rigid tubing must be used to connect the appliance to the gas supply.
Centre the appliance in the fireplace opening taking care not to scratch or damage the hearth.
If a concealed gas pipe fixing is to be used, offer the gas pipe through the appropriate grommet. A nut and olive are provided for an 8mm-
pipe inlet connection to the elbow at the bottom front of the appliance. The elbow can be rotated to allow a connection from any direction.
The elbow includes a valve for isolating the gas supply.
The burner assembly is retained by one screw set in the
front leg (see Fig.5). Remove the screw and carefully
remove the burner assembly by lifting and sliding
forward from the firebox.
FOAM SEAL:A foam seal is supplied which will need
to be attached to the rear face of the firebox frame on all
three sides. Ensure that all joints are butted together to
prevent air gaps.
Figure 5 Burner fixing points
Figure 4 Hearth

CABLE RETENTION
Cables and eyebolts are supplied for the retention of the
appliance. Ensure that the internal fireplace components
are sufficiently sound to take the eyebolts and wall plugs.
These should be fitted in accordance with Figure 6, using
the wall plugs and a No.10 drill. Use only the fibre wall
plugs supplied (or similar). On no account should plastic
wall plugs be used.
Method: Assemble one end of the cable to the top of
the fire by passing it through the small round hole and
locking by positioning the cable end in the adjacent slot.
Pass the other end of the cable through the eyebolt & hole
in the lower side of the appliance and fit adjusters in
accordance with Figure 7. With the adjusters fully
screwed in, carefully manoeuvre the appliance into the
fireplace opening. Take up any slack on the cables, and
tighten cable nipples into position.
Tighten the appliance into the fireplace opening by
turning the adjuster nuts to compress the sealing foam
sufficiently to provide an effective seal. Do not
overtighten.
If the sealing foam does not fully compress, then the
adjusters and nipples may require to be slackened and the cable pulled up
tighter before re-tightening the adjuster. Do not cut off any excess cable,
instead coil up the cable against the flange, as it may be required for
servicing purposes.
FLOOR SEALING
Using the floor sealing tape supplied, seal the bottom of the convection
box to the fireplace and hearth floor. Run the tape over the burner-fixing
bracket.
Replace the burner assembly into position in the firebox, without refitting
the retaining screw at this stage. Cut and shape the gas supply pipe to suit
the chosen direction of entry and the gas inlet fitting position. Refit and tighten the burner assembly retaining screws.
Refit the burner unit to the appliance to the front leg bracket by the screw.
Connect the supply line to the appliance.
For side connection passing in front of the surround. The supply pipe will have to be close to the inner face of the surround to the fire
front casting to be correctly positioned. The pipe should pass through the cutout in the casting side.
For right hand side connection. The supply pipe will also have to be formed to go behind the control knob and burner support bracket.
Pressure check the installation pipework for gas soundness in accordance with the current edition of BS6891. A long brush may be
required to reach some joints.
PRELIMINARY BURNER CHECKS
Some burner operations can be checked at this stage. Checking now will mean that less disassembly will be required it any problems are
found.
A full check should still be made, however, after final installation.
If closed, open the isolating valve at the inlet elbow.
Depress the control knob and turn anticlockwise partially towards the “PILOT/IGN” position until some resistance is felt. Keep depressed
at this position to purge air from the system then, while keeping it depressed, turn fully to the “PILOT/IGN” position. A spark should be
generated at the pilot while turning. The spark should ignite the pilot. If not turn the control knob back to the off position and repeat the
procedure.
When pilot ignition has been achieved, keep the control knob depressed for approximately ten seconds to allow the thermocouple probe to
warm up and then release it. If the pilot does not remain alight, ensure that the air has been purged, that the pilot orifice is clear and that
the thermocouple connections are sound. Replace the pilot unit if necessary (see servicing section of this manual).
When the pilot is alight and stable, partially depress the knob and turn to “LOW”. The pilot should then light the main burner at its low
setting. There may be a delay of up to four seconds between the pilot lighting and ignition of the gas at the main burner. This is normal
and is due to the time required to fill the main burner compartment with sufficient gas for ignition.
When the burner is operating properly, partially depress the control knob and gradually turn it anti-clockwise. The burner flames should
gradually increase until the knob reaches the “HIGH” position.
Figure 6 Cable Retention Method
Fig 7 – Cable Adjustment

When the above checks have been completed partially depress the control knob and turn to “OFF”.
If the above checks are satisfactory, continue with the installation. If not, check the control and ignition circuitry and components as
described in the servicing section of this manual.
CHECK REFERENCE PRESSURE
The appliance is pre-set to give the correct heat input at the inlet pressure shown in the Technical Specification section of this manual. No
adjustment is necessary. Check the burner pressure by fitting a pressure gauge at the test point. The test point is on the pipe situated below
the bottom right corner of the burner unit. Check the pressure with the appliance alight and set at maximum output.
After checking, turn off the appliance. Remove the pressure gauge and replace the test point sealing screw. Relight the appliance. Turn to
the maximum output position and test around the sealing screw for gas soundness with a suitable leak detection fluid.
FITTING THE CERAMICS
Prior to fitting the ceramics, assemble the
Burner tray trim (packed loose) to the front
of the burner tray trim. Simply hook the
trim over the front flanges of the burner
tray and push downwards.
Fit the ceramic rear wall (figures 8 & 9).
The featheredge of the ceramic rear wall
must be at the top.
Place the front base coal in the
burner compartment so that it
rests on the ledges at the sides
and front. Pull the coal
forward so that it is
immediately behind the front
rim of the burner
compartment. (See Fig 10 &
11).

Place the rear base coal in the
burner compartment behind
the front coal. It should rest
on the ledge at the back of the
burner compartment and its
rear face should touch the rear
ceramic wall (See Figure 12 &
13).
Install the 9 loose coals as
follows. The smooth surfaces
of the coals should be at the
bottom and back. Select the
two smallest coals and put
them aside until all the other
coals are installed. Place four
of the medium size coals in
the four valleys of the front
coal. Place the left side coal
so that the customer will be
able to see the pilot flame
(Figures 14 & 15).
Place the three remaining
medium size coals behind and
approximately midway
between each of the coals in
the front row (Figures 16 &
17).
Place the two remaining small
coals alongside the main coals
(Figures 18 & 19).

FULL OPERATING CHECKS
RECHECK CONTROL SETTINGS
Now that all the ceramic fuel effects are in position, the control operation must be fully rechecked.
Make sure that the isolating valve at the inlet elbow is open.
Depress the control knob and turn anti-clockwise partially towards the “PILOT/IGN” position. A spark should be generated at the pilot
while turning. The spark should ignite the pilot. Check that the pilot flame is visible.
When pilot ignition has been achieved, keep the control knob depressed for approximately ten seconds to allow the thermocouple probe to
warm up and then release it. If the pilot does not remain alight, ensure that the pilot orifice is clear.
When the pilot is alight and stable, partially depress the knob and turn to “LOW”. The pilot should then light the main burner at its low
setting. There may be a delay of up to four seconds between the pilot lighting and ignition of the gas at the main burner. This is normal
and is due to the time required to fill the main burner compartment with sufficient gas for ignition.
When the burner is operating properly, partially depress the knob and gradually turn it anti-clockwise. The burner flames should gradually
increase until the knob reaches the “HIGH” position.
Partially depress the control knob and turn back the “PILOT/IGN”. The main burner flames should be extinguished but the pilot should
remain alight.
Partially depress the control knob and turn to “OFF” the pilot should be extinguished.
CHECK FOR SPILLAGE
A spillage check must be made before leaving the installed appliance with the customer. Make this check with the appliance fully
installed with the ceramic fuel effects and front surround in position.
Close all doors and windows in the room containing the appliance.
Light the appliance and turn the control knob to “HIGH”.
Leave the appliance on for five minutes.
Place the smoke match into the appliance canopy (See Fig.20)
The installation is satisfactory if the smoke is drawn into the appliance. If the smoke is not drawn
into the appliance, leave the appliance alight at the maximum setting for a further ten minutes and
then repeat the test. If smoke is still not drawn into the appliance, inspect the sealing to the
fireplace surround. If smoke is still not drawn into the appliance, disconnect the appliance and
seek expert advice.
If the above test is satisfactory, open all internal connecting doors, hatches, etc., in the room. Keep
all doors and windows that open to the outside of the building closed. Recheck for spillage as
above. If an extractor fan is installed in the same room as the appliance or a connecting room,
check that spillage does not occur with the fan operating and all doors and other openings between
the fan and the appliance open.
If the smoke is drawn into the appliance, continue with the installation. If the test is not satisfactory, disconnect the appliance and advise
the customer of the cause of failure.
FLAME SUPERVISION & SPILLAGE MONITORING SYSTEM
This pilot unit incorporates a system that will automatically shut off the gas supply if the pilot flame goes out or if there is insufficient
oxygen due to spillage or lack of ventilation.
This monitoring system must not be adjusted, bypassed or put out of operation.
This monitoring system, or any of its parts, must only be exchanged using Manufacturers thorised parts.

FINAL REVIEW
Place the front casting in position between the sides of the front surround.
Place the bottom front cover casting below the front casting.
Visually inspect the appliance. Clean off any marks incurred during installation.
Hand these instructions and the user’s instructions to the customer.
Advise the customer that the appliance will operate to its maximum potential if the flue is primed during the first 20 – 30 minutes of use.
To do this, simply slide the control to its highest setting. This will also burn off any carbon deposits that may have formed during previous
use.
If using the appliance for long periods it is beneficial to change between settings. This will also help to remove any carbon deposits that
may form during use.This is explained in the Owner’s manual under the section ‘Operating the Fire’.
Point this out to the customer before leaving.
Explain to the customer that the appliance has a flame failure and spillage monitoring system. Point out the explanation of this system
shown in the users instructions under “Operating the Fire”. Advise that if the fire goes out for any reason, wait at least three minutes before
relighting.
Stress that if the monitoring system repeatedly shuts off the fire, the appliance should be switched off and a specialist should be consulted.
Advise the customer that the castings, front surround, firebox and ceramic pieces can be cleaned as described in the user’s instructions and
that the coal pieces must be replace as described in those instructions.
Stress that no extra coals must be added over and above those supplied with the appliance and that any replacements must only be the
authorised spares. Warn that ignoring this advice could cause incomplete clearance of the products of combustion with consequent
health hazards.
Recommend that the appliance should be serviced and the chimney inspected by a competent person (In the UK a CORGI registered
person) at least annually.
If the appliance is in premises in the United Kingdom occupied by a tenant, point out that by law a landlord must have any gas appliance,
flue and pipework which is situated in a tenant’s premises checked for safety at least every 12 months.
