any non combustable materials. This distance must be
extended to a minimum clearance of 610 mm from any
combustable materials.
2.1.1. Hearth
The stove must stand on a fire proof hearth.
To comply with the Building Regulations issued by the
Department of the Environment, the following points
should be noted when choosing a hearth:
- the hearth must be made of non combustible material of
thickness 12 mm minimum.
2.1.2. Fire surrounds
In line with BS 5258 part 13, it is recommended that a fire
surround should not be closer than 610 mm (24”) from the
appliance, if manufactured from a combustible material.
2.2. Flue connection
The Belfort is suitable for both Class 1 and 2 flues (the
building Regulations 1984).
The appliance is also suitable for pre-cast flues, pre-cast
chimney block, pre-cast flue block and ridge tile vent.
It is the responsibility of the installer to ensure that the flue
to be connected is suitable for the conditions experienced
when burning natural or LPG gas.
Ideally it is recommended that a minimum height of
610 mm from the stove should be established before any
significant change in the direction of the flue. Horizontal or
negative gradients in the flue pipe should be avoided.
It is recommended that the flue has a minimum height of 3
metres. Prior to installation the installer should ensure that
the flue is free from obstruction and ideally a chimney
should be swept and subsequently smoke tested. Ensure
that any dampers are fixed in a permanently open position,
and that the chimney/flue is, in the professional opinion of
the installer, of an overall suitability for the purpose inten-
ded.
The stove is supplied with a connection flue spigot with an
inner diameter of 125 mm or an outer diameter of 139 mm.
2.2.1. Smoke exit on the top (page 2, fig. 2)
• Remove the top plate, first remove the 2 screws on the
sides of the appliance.
• Fit the sealing rope in the groove and attach the flue
spigot using the three bolts and washers supplied.
• Check that the two blanking plates are fixed to the back
wall.
• Refit the top plate, ensuring there is a good seal.
2.2.2. Smoke exit at rear (page 2, fig. 3)
• Remove the top plate, first remove the 2 screws on the
sides of the appliance.
• Remove the two blanking plates fixed at the back, fix the
sealing rope in the groove on the top and fit the two
blanking plates on the top, ensuring there is a good seal.
• Fix the sealing rope in the groove on the rear and fit the
flue spigot, using the three bolts and washers supplied,
ensuring there is a good seal.
2.3. Ventilation (G.B. Only)
The Belfort has no requirement for additional ventilation
in the room in accordance with BS 5871 part II.
2.4. Connecting the gas supply
The 8 mm diameter semi rigid gas inlet pipe should be
connected to the inlet of the gas valve using the nut and
8mm olive supplied. Support the control whilst finally tigh-
tening the supply pipe. The gas supply to the fire should be
terminated near the fireplace with a safety type service tap.
2.5. Pressure testing
The gas pressure to the stove must be measured at the
burner test nipple.
- For Propane this is 35.5 mbar measured with the ap-
pliance in the full rate position.
- For Natural gas this is 17 mbar measured with the
appliance in the full rate position.
2.6. Coals layout
Only the ceramic coals supplied with this appliance are to
be used. The coals should only be laid as shown on the
following page. Replacement coals and ceramics are avai-
lable from your dealer.
DO NOT OBSTRUCT THE PILOT
FRANCO BELGE accept no responsibility for any injury
sustained whilst handling hot ceramics.
Instructions for the layout of the prefixed ceramic ma-
trix and loose coals for Belfort fitted with gas burner
unit.
Parts - 1 LH fixed matrix, 1 RH fixed ceramic matrix,
12 ceramic coals.
Stage 1 : Lay the 2 piece ceramic matrix on to the top of
the ceramic mat with two holes on the burner lining up with
one hole in the matrix as shown in page 3, fig. 5.
Stage 2 : Place six coals, one on each spur of the matrix,
with the corners of the coals touching as shown in fig. 6, A.
Stage 3 : Place six coals, each one half on top of the first
layer and one half on top of the matrix, as shown in
fig. 6, B.
2.7. Test for spillage
A spillage test must be performed before the installed fire
is left with the customer.
Carry out the test first by closing all doors and windows in
the room containing the fire.
Ensure that the stove has been burning at full rate for a
minimum of 5 minutes.
Using a smoke match run along the top edge of the draught
diverter.
If most of the smoke is not drawn into the draught diverter
leave for a further 10 minutes and repeat the test. If the
same results are achieved then the appliance has passed
the spillage test.
If there is a fan in a nearby room the spillage test must be
repeated with the fan running and all connecting doors
between the fire and fan left open.
