1.0 Introduction - Page 4
NOTE: A red indicator (Fig. 1) shows when the electric
power is ON but the fan is not running.
The fire incorporates a fan so that it can be installed in a
room without a flue. The fan removes the products of
combustion horizontally through a flue duct which exits
at the rear of the appliance.
1.1 Description
1. The Baxi Belmont 2 and Wentworth Classic Fan Flue are
live fuel effect inset gas fires designed to be used on Natural
Gas only at a setting pressure of 20 mbar.
2. The appliance is designed to give a maximum heat output
of 3.0 kW (10,236 Btu/h).
3. The fire is controlled by a knob which is positioned behind
the controls access door on the fender assembly (Fig. 1).
The knob has four positions:
Position Off
Position Ignition
Position Minimum Output
Position Maximum Output
4. The fan is controlled by the two rocker switches adjacent
to the control knob (Fig. 1).
5. A special feature of the Baxi Belmont 2 and Wentworth
Classic is the direct acting oxygen depletion system. This
system will shut down the appliance if there is inadequate
ventilation and the flue is not clearing the products of
combustion. Under no circumstances shall this device be
adjusted, bypassed or put out of action. The device must
be regularly serviced and strictly in accordance with these
instructions.

Discolouration of wall surfaces
Most heating appliances generate warm air convection
currents and transfer heat to any wall surface against which
they are situated.
Some soft furnishings (such as blown vinyl wallpapers) may
not be suitable for use where they are subject to
temperatures above normal room levels and the
manufacturer’s advice should be sought before using this
type of wail coveting adjacent to any heating appliance.
The likelihood of wall staining from convected air currents
will be increased in environments where high levels of
tobacco smoke or other contaminants exist.
3. Read the instructions before installing or using this

3.0 Site Requirements - Page 7
3.1 Location
1. The Baxi Belmont 2 and Wentworth Classic Fan Flue gas
fires must be installed on an outside wall. The maximum
distance from the rear face of the fire mounting frame to the
outside face of the wall is 600mm. The minimum is 300mm.
The effective wall thickness can be increased by the addition
of an internal fire surround.
2. The flue terminal must be located in a suitable position on
an outside wall taking into consideration the dimensions
shown in Fig. 3.
3.2 Ventilation
1. No purpose provided ventilation is normally required for
the appliance, normal adventitious room ventilation being
sufficient. Reference should be made to BS 5871 Part 2. For
Ireland refer to IS 813 Section 10 of the Irish Ventilation
Requirements.
3.3 Hearth Mounting
1. The fire is intended to be hearth mounted only. The
hearth must be of a non-combustible material at least 13mm
(½ in) thick and measuring at least 325mm (12 7/8in) deep,
measured from the mounting wall face, by 580mm (22 27/32
in) wide. It must be fitted central to the fireplace opening.
The top surface of the hearth should be a minimum of 50mm
(2 in) above floor level (Fig. 4).
2. The fire must also stand on a non-combustible base
inside the fireplace opening, the same height as the hearth.
3. On no account should the fire unit be fitted directly onto a
combustible floor or carpet.
4. Alternatively, a fender rail or upstanding edge of 50mm
(2in) height can be fitted to the periphery of the 13mm (½ in)
non-combustible hearth (Fig. 5).
3.4 Purpose Built Hearths & Surrounds
1. Purpose built fire resistant hearths and back panels
specified as suitable by the manufacturer, or a suitable
propriety fire surround with 150º C rating may be used.

9
3.0 Site Requirements - Page 8
3.5 Clearances (Fig. 7)
1. Shelf Clearance - minimum clearance from the hearth to
the underside of a combustible shelf should be 830mm
(3221/32 in) provided the shelf depth is 150mm (529/32 in) or
less. When the shelf depth is increased by increments of
12.5mm (15/32 in) greater than 150mm (529/32 in), add 25mm
(1in) to the 830mm (3221/32 in).
2. Side of Fire - minimum width between vertical sides of a
combustible surround should not be less than 675mm (265/16
in) provided the fire is central to the surround and the sides
do not project forwards more than 150mm (529/32 in). For
every 12.5mm (½ in) that the projection of the sides is
increased by, add a further 50mm (2 in) to the inside width of
the surround. NOTE: When the fire is fitted, this gives a
minimum side clearance of 150mm (529/32 in).
3.6 Gas Supply & Connection
1. The gas supply is to be connected to the appliance as a
concealed fix from the rear.
Turn off any appliances that are fed by the meter and
isolate the gas supply by turning off at the meter.
2. It is advisable to route the supply to the left side of the
unit taking into account the requirements of BS 6891:1988
dealing with enclosed pipes.
3. It is necessary to remove the grommet from the left hand
hole in the fire back panel. The grommet must be cut in
order to accommodate the gas pipe and replaced as in Fig.
8. The pipe can then be routed to the inlet elbow. (Fig. 9)
4. A suitable isolating cock should always be fitted in the
supply feed to the fire to facilitate servicing.

5.0 Installation - Page 11
5.1 Initial Preparation
1. Unpack the appliance from the carton and check all items
are present. The ceramic coal bed items should be left in
their box until required.
2. Some sheet metal parts may be fitted with protective
plastic coating which must be removed prior to installation.
5.2 General Preparation
1. Make sure the chosen position will comply with the
installation requirements detailed in section 3.0 Site
Requirements.
2. Make sure the damp course and any electrical wiring or
piping in the wall is not affected by the installation.
3. Any gas supply pipe concealed in a wall, floor or cavity
must be continuous and enclosed in a gas tight sleeve. (Gas
Safety (Installation and Use) Regulations 1994 as
amended).
4. The fire can be fitted into a surround or false chimney
breast in front of a non-combustible wall, into a recess within
a brick, block or stone cavity wall, or into a timber framed
dwelling.
5.3 Preparation of the Site - Fire In front of the wall
1. This installation details the use of a fire surround or false
chimney breast having a minimum depth of 140mm. This will
allow the fire to be positioned in front of the wall with a hole
in the inner wall for the flue only. The maximum surround
depth will depend upon the wall thickness. The maximum
total depth is 600mm from the outer wall face to the rear face
of the outer fire frame. The minimum total depth is 300mm.
2. Any combustible material within the installation must be
at least 75mm away from the appliance, the flue box and the
circular horizontal flue.
3. A suitable liner should be made to enclose the fire
(Fig. 11). This should be fitted within the false fire surround.
It should be 24mm thick and be of Supalux or similar non-
combustible board. If 24mm material is not available two or
more smaller boards may be used. It should extend from the
outer fire frame to the inside face of the wall. When fitted,
this box should be insulated to the top and sides with
100mm of Rockwool (Fig. 12).

13
5.0 Installation - Page 12
5.3 Preparation of the Site (cont)
4. Measure 400mm up from hearth level and mark this
dimension on the wall. Drill through the inner and outer walls
at the mark using a suitable pilot drill at a point
corresponding to the centre line of the fire flue outlet (Fig.
14).
5. From outside consider the position of the pilot hole in
relation to the brickwork. The fan box is 3 bricks high and
requires a cut-out in the wall 95mm above and 120mm
below the pilot hole. This cut-out must extend 100mm to the
left and 220mm to the right of the pilot hole (Fig. 13).
6. If the position of the fan box cut-out would be such that it
does not coincide with the brick courses the pilot hole
position can be re-marked 40mm up or down. The fan box
cut-out can then be marked relative to this new position.
7. If this is necessary the flue outlet on the rear of the fire
can be adjusted accordingly by undoing the six securing
screws. It may be necessary to remove the flue outlet plate
and fit it the other way up to achieve the desired ammount of
adjustment. Precise adjustment of the flue height can be
carried out when the flue duct is fitted.
8. Cut a hole 100mm diameter in the inner wall at the
required height for the flue duct.
9. A separate hole approximately 35mm diameter should be
made through the inner wall towards the bottom right hand
corner of the fire location to enable the electrical cables to
pass through the wall and connect the fire to the fan box and
allow for the 230V supply cable to the fan box.
10. From outside cut a neat rectangular hole for the fan box
assembly. The cavity should be sealed where the flue duct
will pass through. Use Rockwool or similar to each side of
the opening to a thickness of at least 100mm.
Proceed to section 5.5 Fitting the Fan Box

14
5.0 Installation - Page 13
5.4 Preparation of the Site - Fire fitted Into a recess
1. A suitable liner should be made to enclose the fire (Fig.
16). This should be fitted within the false fire surround. It
should be 24mm thick and be of Supalux or similar non-
combustible board.
If 24mm material is not available two or more smaller boards
may be used. It should extend from the front of the fire
mounting face to the inside face of the outside wall. The
outside of this box should be insulated to the top and sides
with 100mm of Rockwool when the box passes through the
cavity between the inner and outer walls.
2. A hole 100mm diameter must be cut centrally in the rear
panel of the liner for the flue duct. The height of the hole
should be the height at which the pilot hole is to be drilled, or
at its’ adjusted position-see paragraph 4 to 7 below and
Fig. 14. Also a hole approximately 35mm diameter should be
cut in the lower right of the liner to accept the electrical
cables.
3. Mark the position of the recess to be cut for the fire on the
inside wall.
N.B. A lintel may be required above the cavity for the fire. If
in doubt seek expert building advice.
4. Cut the cavity in the inner wall for the fire. Measure
400mm up from hearth level and mark this dimension
centrally on the inner face of the outer wall. Drill through
outer wall at the mark using a suitable pilot drill.
5. Consider the position of the pilot hole in relation to the
brickwork. The fan box is 3 bricks high and requires a cut-out
in the wall 95mm above and 120mm below the pilot hole.
This cut-out must extend 100mm to the left and 220mm to
the right of the pilot hole.
6. If the position of the fan box cut-out would be such that it
does not coincide with the brick courses the pilot hole
position can be re-marked 40mm up or down. The fan box
cut-out can then be marked relative to this new position.
7. If this is necessary the flue outlet on the rear of the fire
can be adjusted accordingly by undoing the six securing
screws. it may be necessary to remove the flue outlet plate
and fit it the other way up to achieve the desired ammount of
adjustment. Precise adjustment of the flue height can be
carried out when the flue duct is fitted.
8. From outside cut a neat rectangular hole for the fan box
assembly.
Proceed to section 5.5 Fitting the Fan Box

9. This installation requires a 150mm diameter piece of
single wall flue pipe or similar for use as a metal sleeve
(Fig. 19).
10. This installation details the use of a fire surround or false
chimney breast, having a minimum depth of 140mm, which
allows the fire to be positioned in front of the wall with a hole
in the inner wall for the flue only. The maximum surround
depth will depend upon the wall thickness. The maximum
total depth is 600mm from the outer wall face to the rear face
of the outer fire frame. The minimum total depth is 300mm.
11. Any combustible material within the installation must be
at least 75mm away from the appliance, the flue box and the
circular horizontal flue.
12. Installation must be in accordance with the current
edition of Institute of Gas Engineers Publication IGE/UP/7
(Gas Installations in Timber Framed Housing).
13. A suitable liner should be made to enclose the fire. This
should be fitted within the false fire surround. It should be
24mm thick and be of Supalux or similar non-combustible
board. If 24mm material is not available two or more smaller
boards may be used. It should extend from the outer fire
frame to the inside face of the wall. When fitted, this box
should be insulated to the top and sides with 100mm of
Rockwool.
14. The back surface of the fire must be separated
from the timber frame by 25mm of non-combustible material.
This can consist of the usual 13mm plasterboard wall lining
plus 12mm of Supalux or similar non-combustible board.
15. Measure 400mm up from hearth level and mark this
dimension on the wall. Drill through the inner and outer walls
at the mark using a suitable pilot drill, centrally in any
surround.

5.4 Preparation of the Site (cont)
16. Taking into consideration the dimensions in fig.13 and 14
on page 12 and the position of the pilot hole, cut a suitable
hole for the flue box assmebly.
17. Once the height of the flue has been determined make a
hole through the wall to accept a 150mm diameter sleeve.
Ensure that when the 150mm diameter hole is cut through
the wall and the rectangular recess is cut in the outer wall,
no timbers are cut.
18. Make sure that the vapour barrier is cut carefully and
made good to maintain its integrity.
19. A separate hole should be made towards the bottom
Right Hand corner of the fire location to enable the electric
cables to pass through the wall and connect the fire to the
flue box and allow for the 230V supply cable to the fan box.
20. The cavity should be sealed where the flue box hole has
been cut. Rockwool or equivalent may be used, it should be
fitted above and to each side of the opening to a thickness of
at least 100mm.
21. A sloping plate should be fitted above the 150mm
diameter sleeve in accordance with IGE Publications DM2
Section 6.1.5 (b).
22. Measure the length required for a 150mm diameter metal
wall sleeve, which should fit between the inside wall face
and the inside of the outer wall or the rear of the fan box,
which ever is the closer to the fire. Cut to length and fit into
the 150mm diameter hole. Seal any gaps with a suitable
sealant at each end.

5.6 Fitting the Fire
1. There are 2 methods of fixing the fire in position, using
the eyebolts and cables or simply screwing through the outer
fire frame with 4 screws to the wall or surround face.
NOTE: It is recommended that the appliance is screwed
to the wall or surround face. The eyebolt and cable
method can only be used when the appliance is installed
in a false chimney breast or surround.
2. Either mark the wall as shown (Fig. 26) and drill, plug and
fit the 4 eyebolts (Fig. 25) or mark the front face of the
surround using the fire as a template and drill and plug the 4
holes, 2 at each side. The top 3 holes may also be used if
required to ensure a good seal between the fire and the
surround (Fig. 27).
3. With the gas supply routed from the rear, mark as shown
(Fig. 26) and install the pipework after considering section
3.6 Gas Supply and Connections.
4. Take the foam seal from the kit and remove its backing
strip. Fit it to the rear of the fire frame (Fig. 27).
5. Measure the space between the front wall fixing face and
the outside wall. Check that the telescopic flue can be set at
the appropriate length. Each of the flue ducts may be
reduced in length to allow short flues. The overlap must be
maintained at a minimum of 30mm.
6. If the wall thickness is at the minimum (300 mm) both flue
ducts must be cut to 65mm.
7. Fit the smaller diameter flue duct to the fire outlet,
ensuring it is located correctly and the seal is made.
8. Undo the 3 screws retaining the burner chassis to the
combustion box sides and base. Withdraw the chassis and
