1 APPLIANCE DATA
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 a tie below the burner and is visible when the bottom front
cover is removed.

the Environment for Northern Ireland.
In the republic of Ireland the installation must also conform to the relevant parts of:
a) The current edition of IS 813
b) All relevant national and local rules in force.
2.2 In the United Kingdom, as supplied, the appliance can be installed in the following
situations:-
2.2.1 To a fireplace complete with surround and hearth as shown in figure 1 and
complying with BS1251 after removal of the fireback and sufficient material behind the
fireback for a debris catchment space. The required fireplace, hearth, debris catchment
area and clearance dimensions are shown in figure 1.
2.2.2To a fireplace incorporating a metal flue box complying with the constructional
requirements of the current edition of BS715. The dimensions of the flue box must
conform to those shown in figure 2.
2.2.3 If the fireplace opening is greater than the acceptable dimensions given in this
guide, do not use the back of a fire surround or marble to reduce the opening. This may
cause cracking of the surround
back or marble.
2.3 With the addition of
optional accessory spacing kit
617K together with a
sufficiently deep surround and
hearth, this appliance can be
fitted in the following
situations. Full installation
requirements and instructions
are provided with the kit:-
2.3.1 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

INSTALLER’S GUIDE
Page 6
Fig. 3 Precast or clay flue block system
Requirements for use with kit 617K
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 distance from the back
face of the flue starter
blocks to the extreme front
face of the fireplace
including all surfacings
must be no less than the
distance shown in figure 3.
The distance from the front
face of the flueway
opening in the lintel block
(or equivalent) to the
extreme front face of the
fireplace including all
surfacings must be no more
than the distance shown in
figure 3. If this maximum
is exceeded poor clearance
of combustion products could result.
The flue starter blocks should not be modified.
The current versions of BS1289 and BS EN 1806 recommend 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.
2.3.2 Into a fireplace that has a fireback of nominal size 400mm or 450mm and
conforming to BS1251. The distance from the front face of the flueway opening in the
lintel (or equivalent) to the extreme front face of the fireplace including all surfacings
must be no more than the distance shown in figure 4. If this maximum is exceeded poor
clearance of combustion products could result.

Requirements for use with kit 617K
2.4 Suitable flues and
minimum flue sizes are as
follows:-
It should be noted that, as with
many appliances, sharp bends
or horizontal runs in metal
flues at the top of the system
can be a cause of problems in
these types of installation.
•225mm x 225mm
conventional brick flue.
•175mm diameter lined brick
or stone flue.
•200mm diameter factory
made insulated flue
manufactured to BS4543.
•175mm diameter flue pipe.
See BS6461 Part 1 for suitable
materials.
•Single wall, twin wall or
flexible flue liner with a
minimum diameter of 125mm.
The materials to be used are
stainless steel or aluminium as specified in BS715. The liner must be sealed to the
surrounding area above the fireplace opening and to the top of the chimney. An approved
terminal must be fitted.
•A properly constructed precast concrete or clay flue system conforming to BS1289 or
BS EN 1806. This system is only suitable if the conditions stated in section 2.3 are met.
2.5 The flue must conform to BS 5440: Part 1 in design and installation.
The flue, measured from the bottom of the fireplace opening to the bottom of the
terminal, shall be not less than 3m in actual vertical height. When calculated in
accordance with BS 5440: Part 1 Annex A, the minimum equivalent height of the flue
shall be 2.0m of 125mm dia. flue pipe.
2.6 The flue must not be used for any other appliance or application.
2.7 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.

INSTALLER’S GUIDE
Page 8
2.8 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.
2.9 If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
2.10 The appliance must be mounted behind a non-combustible hearth (N.B.
conglomerate marble hearths are considered as non-combustible). The appliance can be
fitted to a purpose made proprietary class “O”-150°C surround. The hearth material must
be at least 12mm thick. 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.
The surface of the hearth must be sufficiently flat to enable the bottom of the front
surround and the bottom front cover to be aligned horizontally. Any excessive
unevenness (uneven tiles, Cotswold stone, etc.) should be rectified.
The appliance must not stand on combustible materials or carpets.
2.11 The front face of the fireplace should be reasonably flat over the area covered by
the convection box top and side flange seals to ensure good sealing. These faces should
be made good if necessary.
The fireplace floor should be reasonably flat to ensure that a good seal with the
convection box can be made.
2.12 The minimum height from the top surface of the hearth to the underside of any
shelf made from wood or other combustible materials is shown in graph 1.
2.13 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance. Please
bear this in mind when installing.
2.14This appliance must not be installed in any room which contains a bath or shower or
where steam is regularly present.
2.15An 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.

INSTALLER’S GUIDE
Page 9
2.16 In the United Kingdom (GB) no special ventilation bricks or vents are required in
the room for this appliance.
In the Republic of Ireland (IE) permanent ventilation must comply with the regulations
currently in force.
2.17 Propane gas appliances must not be installed in a room which is built entirely
below ground level (See BS 5871 Part 2).
Graph 1 Combustible shelf clearances

INSTALLER’S GUIDE
Page 10
Fig. 5 Appliance dimensions
2.18 If the appliance is to be fitted against a wall with combustible cladding, the
cladding must be removed from the area covered by the outer surround (see figure 5). We
suggest that the actual surround is used as a template to mark the area for combustible
cladding removal.
2.19 The minimum allowable distance from the outside of the appliance case to a corner
wall having combustible material or any other combustible surface which projects
beyond the front of the appliance is 108mm at either side.
This clearance is also the minimum recommended at the right side in all installations to
allow satisfactory access to the control knob. No access clearance from a non-
combustible surface is necessary at the left side. See figure 5.
2.20 Proprietary terminals must comply with BS 715 or BS 1289. Any terminal or
termination must be positioned in accordance with BS 5440 Part 1 to ensure that the
products of combustion can be safely dispersed into the outside atmosphere. Where the
appliance is connected to an unlined brick chimney it is generally unnecessary for the
chimney pot to be replaced or for a terminal to be fitted unless the flue has a diameter
smaller than 170mm.

Figure 7 Fireplace Areas
4 FIREPLACE CHECK
4.1 Installations Not Requiring Optional Spacing Kit 617K
4.1.1 Fireplace size
The fireplace must comply
with the requirements
described in section 2.2. This
will probably entail removing
the fireback and infill material
behind the fireback. The
debris catchment area shown
in figure 7 must be kept clear
of obstructions.
4.1.2 Fireplace general
condition
The fireplace floor should be
reasonably flat to ensure that
the convection box can be
installed without it rocking
and so that a good seal can be made at the bottom front of the box. The front face of the
fireplace should be reasonably flat over the area covered by the convection box top and
side flange seals to ensure good sealing. These faces should be made good if necessary. If
the appliance is to be fitted against a wall with combustible cladding, the cladding must
be removed from the area covered by the fire front surround (see figure 5). We suggest
that the actual fire front is used as a template to mark the area for combustible cladding
removal.
4.1.3 Soundness for appliance attachment
Two primary methods of retaining the appliance are provided:-
1) By fixing to the fireplace front surround.
2) Using concealed tension cables fixed to the rear of the fireplace opening together
with secondary fixing to the fireplace floor.
The methods are detailed in section 8 of this manual. Before selecting the retention
method, consult with the customer. Method 2 is provided for instances where drilling
holes in the front surface of the fireplace surround is unacceptable to the customer or
otherwise impractical. N.B. It is unwise to attempt to drill into marble without the proper
tools and equipment.
If method 1 is chosen, make sure that the front surround area is sound enough to take the
rawlplugs and woodscrews. If necessary, make sound with a suitable cement.

INSTALLER’S GUIDE
Page 13
If method 2 is chosen, make sure that the areas at the back and towards the centre of the
fireplace floor are sound enough to take the eyebolts and screws. If these areas have
deteriorated due to prolonged use, they should be made sound with a suitable cement.
4.1.4 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a 100mm layer
of mineral wool or equivalent insulation (see figure 2).
4.2 Installations Requiring Spacing Kit 617K
The accessory kit 617K must be used for all installations described in section 2.3 of this
manual. Full instructions for its installation are included with the kit.
4.3 Fireplace Flue Pull
Close all doors and windows in the room in which the appliance is to be installed. After
confirming with a match that smoke is drawn into the flue, light a 13 gram smoke pellet
and check that there is a definite flow through the flue. Verify outside that the smoke
exits from one terminal only and that the termination is suitable. Observe, where
possible, upstairs rooms and loft spaces for signs of escaping smoke indicating a
defective flue. If there is not a definite flow warm the flue for a few minutes and repeat
the smoke pellet test. If there is still no definite flow the flue may need remedial work –
Do not fit the appliance until there is a definite flow through the flue.

5 IGNITION CHECK
Before attempting to install, it is worth checking that
the electronic ignition system performs satisfactorily.
●Fit the battery to the ignition block located below
the burner tray at the left side (see figure 8). The
positive terminal (+) is to the right as you insert.
Depress the slider as far as it will go. This should close
the ignition circuit. Sparks should be seen tracking
from the electrode pin to the thermocouple tip. See
figure 9.
●If there are no sparks
make the following checks.
a. Check condition of
battery and that it is
correctly fitted.
b. Check spark gap
between electrode wire
and thermocouple tip.
See figure 10.
c. If a & b are satisfactory, check the ignition circuit and
components - see the servicing section in this manual.
6 GAS SUPPLY CONNECTION
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 supply pipe must be rigid material. Flexible pipe must not be used.
6.1 Concealed Supply Pipe Connection
If a concealed connection from inside the fireplace is required then, before the
appliance is fitted into the fireplace it will be necessary to extend the supply line so
that it will project through the sealed opening at the back of the convection box and run
to the elbow at the front. If the installation includes the optional spacing kit 617K, the kit
and surround should be installed before extending the supply line.
The pipe run from the supply line up to the rear opening in the convection box must be
kept away from the area which will be taken by the convection box when it is installed
(See figure 7).

Fig. 12 Front Surround Bottom
Location
Fig. 13 Front surround top location
Note that the centre of the appliance inlet elbow is 25mm above the fireplace floor. The
inlet elbow should be removed from the appliance and fitted to the supply pipe at this
stage.
6.2 Side Supply Pipe Connection
The appliance is designed to allow a side supply pipe to run in front of the front surround
and through a cut- out at either rear bottom corner of the fire front casting. For side
connection, final installation of the supply pipe should be left until the appliance is
installed in the fireplace. For a right side connection the pipe will have to be formed to
clear the burner unit mechanism.
7 PREPARING APPLIANCE FOR
INSTALLATION
1. Detach the control linking bar from the
control pivot bracket by removing the knurled
screw which joins the control linking bar to the
control pivot unit. See figure 11.
2. Remove the two screws securing the bottom
of the front surround to the sides of the convection
box. See fig. 12.
3. Make sure that the control linking bar has
been detached (see 1 above). Carefully lift the
surround unit upwards to clear the upper retaining
brackets on the convection box - See figure 13.
Pull the surround clear and place carefully aside.

INSTALLER’S GUIDE
Page 16
Fig 16 Fireback Spacers
Fig. 14 Burner Attachment Points
Fig. 15 “U” Seals
4. Detach the burner unit from the convection
box by removing two screws - See figure 14. Lift
the burner unit clear.
5. Fit the two “U” section seals to the bottom
edges of the convection box side flanges. The
seals should cover the front edges and the side
edges up to where they meet the convection box
base - See figure 15.
6. For concealed connection only: Pierce a hole in
the seal at the back of the convection box. The seal
must envelop the pipe. If the hole is larger than the
pipe, seal it with tape. Do not pierce the seal unless
the supply pipe is to
pass through it.
7. The appliance is
supplied with two
fireback spacers
extending backwards to
ensure sufficient
clearance from the back
of the fireplace when
installed without the
spacer kit 617K. If the
appliance is being
installed with the spacer
kit, reverse the fireback
spacers. This will give
the minimum rear
clearance required when
used with the spacer kit -
See figure 16. If the kit
is not used do not
reverse the fireback
spacers. Never totally
remove the spacers.
8. This appliance is
supplied with a flue
restrictor for use where
the flue draught is
excessive. The restrictor

INSTALLER’S GUIDE
Page 17
Fig. 17 Flue Restrictor
Fig. 18 Front Fixing
must NOT be fitted where a precast flue or a flue
liner is used. For all other installations the restrictor
should be fitted. There may however, be certain
exceptional circumstances where fitting the restrictor
causes the fire to fail the spillage test. In such cases
the restrictor will have to be removed. After removal
conduct the spillage check again.
The restrictor is packed loose with the appliance and
is fixed with three screws. See figure 17.
8 CONVECTION BOX INSTALLATION
8.1 Installations Without Spacer Kit 617K - Method 1
- Front Fixing to Fireplace Surround
1. Make sure that the fireplace front surround area is
sound enough to take the rawlplugs and woodscrews. If
necessary, make sound with a suitable cement.
2. Place the convection box centrally in the fireplace in the
position in which it is to be permanently installed. If a
concealed connection is being used, insert the convection
box into the fireplace feeding the supply pipe through the
pierced hole in the rear seal.
3. Mark the fireplace front surround through the four
fixing holes in the side flanges of the convection box. See
figure 18.
4. Remove the convection box. Drill four holes in the fireplace front surround at the
marked positions using a no.12 masonry drill.
5. Insert a rawlplug into each hole.
6. Place the convection box back in position in the fireplace.
7. Fit a woodscrew through each hole in the convection box flanges and tighten to seal the
box to the fireplace surround.

Fig. 19 Eyebolt Positions
Fig. 20 Upper Cable Retention
Fig. 21 Cable Route
8.2 Installations Without Spacer Kit
617K - Method 2 - Cable
Retention and Floor Fixing
1. Make sure that the relevant areas at
the fireplace back or floor are sound
enough to take the eyebolts and screws.
If these areas have deteriorated due to
prolonged use they should be made
sound with a suitable cement.
2. Drill two holes in the rear wall or
floor of the fireplace for the eyebolt
plugs. The holes should be drilled within the range of
positions shown in figure 19 using a no.12 masonry
drill. The holes should be equidistant each side of the
centre line of the fireplace to ensure that the appliance
finishes centrally in the opening when tension is
applied to the cables.
3. Insert a fibre plug into each hole. Use the
rawlplugs supplied with this appliance - Never use
plastic plugs instead of the fibre plugs supplied.
Screw the eyebolts into the plugs. Make sure that the
bolts are secure.
4. Place the convection box unit close to the fireplace but
allow sufficient access into the fireplace opening so that the
cables can be threaded through the eyebolts and returned
through the back of the convection box. If a concealed
connection is being used, insert the convection box into the
fireplace feeding the supply pipe through the pierced hole in
the rear seal.
5. The convection box has two holes at each side of the
convected air opening. Insert one end of each cable (one
cable each side) from the back through the lower of the two
holes and return the end through the upper of the holes. See
figure 20. Give the cables a pull so that they grip against the
convection box flanges.
6. Thread the cables through the eyebolts. Return the cables through the holes near the
bottom of the convection box back panel and through the “V” shaped brackets near the
bottom front sides of the convection box - See figure 21.
7. Place the convection box fully back into the fireplace opening so that it is sealed

INSTALLER’S GUIDE
Page 19
Fig. 22 Lower Cable Retention
Fig. 23 Floor Fixing
Fig. 24 Spacer Attachment
Points
against the fireplace front surround.
8. Fit a cable retainer over the bottom
end of each cable.
9. Pull each cable taut. Push the cable
retainers hard up against the “V”
brackets. Tighten the screws in the
retainers so that they clamp the cables in
position. Apply tension to the cables by
turning the hexagonal adjusters by hand.
See figure 22.
10. Drill a hole into the fireplace floor through
each of the two holes in the base of the
convection box using a no.12 masonry drill. See
figure 23.
11. Insert a fibre plug into each hole. Use the
rawlplugs supplied with this appliance - Never
use plastic plugs instead of the fibre plugs
supplied.Fit a woodscrew in each plug and
tighten.
12. Inspect the installation of the convection box
against the fireplace surround. If the convection
box is aligned squarely and the sealing is
satisfactory, fully tighten the cable retainers.
13. If the convection box is not correctly aligned, release
the tension on the cables by slackening the screws and
turning the hexagonal adjusters fully anticlockwise. The
convection box should then automatically realign itself. Pull
each cable taut again and push the cable retainers back
against the “V” brackets. Again, tighten the screws in the
retainers and apply tension to the cables by turning the
hexagonal adjusters clockwise as far as possible.
14. Push the free length of the cables inside the convection
box so that they are available to allow easy removal and
refitting of the appliance during subsequent service calls.
8.3 Installations With Spacer Kit 617K
1. There are 9 indented positions on the front flanges of the
convection box. Drill a 5.5mm hole through each indent - See figure 24.
2. Place the convection box unit into the installed spacer kit opening. Align the 9 drilled
holes with the holes in the spacer unit sides and top. If a concealed connection is being

9 BURNER & SUPPLY PIPE
INSTALLATION
9.1 Burner & Supply Pipe Installation
1. Refit the burner unit to the convection box
with two screws.
2. Connect the supply line to the appliance.
3. Pressure check the installation pipework
for gas soundness. In the United Kingdom
check in accordance with the current edition
of BS6891. In the Republic of Ireland check
in accordance with the rules in force.
9.2 Preliminary Burner Checks
Some burner operations can be checked at
this stage. Checking now will mean that less
disassembly will be required if any problems are found. A full check should still be
made, however, after final installation.
1. If closed,open the isolating valve at the inlet elbow.
2. Rotate the control pivot bracket clockwise as far as it will go and hold in this position
(See figure 26). This should close the ignition circuit and simultaneously open the gas tap
allowing the gas to flow to the pilot. Wait a few seconds while the air is purged. The
electronically generated sparks should light the pilot. 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.
3. When the burner is operating properly, gradually turn the control pivot bracket anti-
