2.1 Warning to the user
All the local and national regulations, and
in particular those relating to national and
European standards, must be observed when
installing the appliance.
An incorrectly installed heating appliance can
cause serious accidents (chimney res, burning of
plastic insulation materials in partition walls, etc.).
The insulation of both the appliance and the exhaust
gas pipe has to be reinforced and done according to
the Standards and the Bui lding Regulations for safety
reasons. The installation must be carried out according
to the standards and the Building Regulations.
It is the installer responsability to ensure that the
manufacturer's intructions are complied with.
2.2. The room
Ventilation : To ensure that the appliance operates
correctly it is vital that sufcient air is provided for
combustion purposes. Check that sufcient air is
available in the room for combustion. Il a VMC
(controlled mechanical ventilation) is present, the
room pressure will be low and a non-closing external
air intake must be installed in addition to the chimney
itself of a minimum 50 cm2.
Position of the unit : For new installations, select a
central position within the house, to provide a good
heat distribution around the building.
The heat distribution towards the other rooms will be
made through the communicating doors.
These rooms must be in negative pressure or must
include ventilation gratings.
Floor and walls :
Make sure that the oor can support the weight of the
appliance, it's ue and any surround. The oor May
need to be re-inforced with e concrete screed to
distribute the weight load. The oor must not be
made of or covered with combustible materials, as
per the Building Regulations. Il combustible material is
present it will be necessary to install a non-combustible
covering.
There must be a clearance of at least 150 mm at each
side of the appliance and at the back of the appliance
from a non-combustible wall.
This distance must be extended to a minimum
clearance of 550 mm from any combustible materials
(gure 2a). This measurement may be reduced to a
minimum gap of 50 mm when the non-combustible
wall is at least 200 mm thick.
When using a single wall ue pipe, there must be a
clearance (A) of at least three times its diameter (B)
from any combustible materials.

If the appliance has to be located in an opening, this
distance must be extended to a minimum clearance
(A) of 550 mm from the pipe or the stove body to any
combustible materials.
Hearth : The appliance must stand on a reproof
hearth.
It is possible to provide a hearth made of non
combusible board/sheet material or tiles at least 12
mm thick (C).
Constructional hearths should be constructed of
solid non combustible material at least 125 mm thick
(including the thickness of any non combustible oor
under the hearth).
The hearth must protrude at least 225 mm in front of
the stove and 150 mm each side.
If the hearth is constructed on timber, there must be
a clearance of at least 250 mm from the timber to the
top surface of the hearth. See section J of the Building
regulations.
Do not place any combustible materials in front of the
stove within a distance of 115 cm.
Be aware that the distances given are the minimum
required, however take into consideration that
you need to have sufcient space for cleaning and
maintenance purposes.
Do not place any object or combustible material,
curtains, hangings, etc... within the safety
distances.
2.3. Chimney
Existing ue : The chimney must comply with
Current Building Regulations. If in doubt, consult your
Dealer or local Building Inspector.
- The ue must be in good condition and must provide
sufcient draught.
- The ue must be suitable for the installation of solid
fuel burning appliances and comply with Current
Building Regulations.
- The ue must be clean. It should be swept to remove
soot and dislodge tar deposits.
- The ue must be well insulated. If the ue inner wall
surfaces are cold, a good thermal draw is impossible
causing condensation problems (tar formation etc) to
occur.
- The ue must not be shared with other appliances.
- The chimney must be at least 4.5 m (15 ft high).
- In case of a at roof or when the roof gradient is
lower than 15°, the stack must be 1,2 m (4 feet) high
at least.
- If the chimney has any down draught tendency, due
to its position in relation to nearby obstacles, then an
anti-down draught cowl must be installed on the
chimney or the chimney height must be increased.
- If the decompression in the chimney is excessive, a
draught stabiliser must be installed.
Chimney to be built / new ue : The chimney
must comply with Current Building Regulations. If in
doubt, consult your Dealer or local Building Inspector.
- The appliance must not support the weight of the
ue.
- Consult a chimney specialist for advice on suitable
ue systems for solid fuel appliances.
- It must be distant from any combustible material
(walls, cross members)
- Easy sweeping access must be provided.
2.4 Mounting the ue collar

1 diameter lower than the ue spigot and be situated
as distant as possible from the ue connection of the
appliance.
- The connection can be either vertical or horizontal.
For horizontal connections, avoid right angle bends.
- The join between the connection pipe and the
stovepipe, and the ue, must be leak tight.
- For the premises equipped with a mechanical
controlled ventilation, the airtightness has to prevent
the exhauster drawing out the smokes from the
exhaust gas pipe.
- The connection pipe and any draught stabiliser must
have access for cleaning.
- The spigot should be connected to a minimum of
125 mm ue system and in that case the appliance is
capable of burning untreated wood.
2.8. Pre-utilisation check
Check the condition of the door rope seals. Check the
door closes correctly ans that the glass is not damaged.
Ensure that all internal packaging materials have been
removed and are not blocking any of the air passages.

3. Instructions for user
All the local and national regulations, and
in particular those relating to national and
European standards, must be observed when
using the appliance.
Do not run the stove in mild weather with fuel. Under
certain circumstances such as fog and repeated thaw,
the chimney will not draw sufciently and could
cause smoke to return to the room which could cause
asphyxia. Await improved weather conditions before
attempting to burn fuels again however you can
continue to use the appliance with Wood.
On the rst ring, a Small re should be lit and be
increased gradually to enable the various components
to expand normally and for the appliance to cure
correctly.
Note : When the re is lit for the rst time, the stove
may give off fumes from the new paint. This is normal
but ensure the room is well ventilated during the rst
few hours of operation.
Warning : properly installed and operated this
appliance will not emit fumes into the dwelling.
Occasional fumes from de-ashing and re-fuelling may
occur. Persistent fume emission is dangerous and must
not be tolerated. If fume emission does persist :
Open doors and windows to ventilate room.
Let the re out and dispose of fuel from the appliance.
Check for ue or chimney blockage, and clean if
required.
Do not attempt to relight the re until the cause of the
fume emission has been identied and corrected. If
necessary seek expert advice.
Note : It is recommended to use a reguard in the
presence of children, and also in the presence of old
and/or inrm people.
3.1. Fuel
This appliance is not an incinerator.
Recommended fuel : Wood
• Use hard wood logs, which have been cut for at least
two years and stored, under shelter.
• Hardwood has a higher caloric value per cu metre
(oak, ash, maple, birch, elm, beech, etc.).
• Large logs must be split and cut to a usable length,
before being stored in a sheltered and ventilated place.
Not recommended as fuel :
• “green wood”. Green or damp wood reduces stove
efciency and soils the glass, the internal walls and
the ue (soot, tar, etc.).
• “used timbers”. Burning treated wood (railway
sleepers, telegraph poles, offcuts of plywood or chip
board, pallets, etc.) quickly clogs the ue ways (soot,
tar, etc.), pollutes the environment (pollution and
smell, etc.) and cause the re to burn too quickly and
overheat.
• “Green wood” and “recovered wood” can eventually
cause a chimney re.
The manufacturer will not be responsible for
any damage caused to the appliance due to the
incorrect use or installation of the appliance e.g.
prohibited fuel use and any alterations made to
the appliance which have not been authorised by.
the manufacturer. We recommend that you use
only the manufacturer's own brand spare
parts.

• Prohibited fuel : Homere and any form of
bituminous coal or petroleum based coke.
3.2. Instructions for use with wood
(Figure 8)
3.2.1. Lighting
• Slide the secondary air inlet (# B1) to the right Open
the primary air inlet (# C1) during 10 minutes.
• Lay relighters or rolled up newspapers on the grate
with a reasonable quantity, if necessary, of dry kindling
wood.
• Light the newspaper or relighters using a long taper
and push the door to against the latch without closing
it.
After a few minutes, when the ames from the kindling
are reducing, add two small logs (half logs) and left
the door ajar again.
Wait a few minutes for add a full load, and again left
the door ajar until the load is burning well.
Close the door and the primary air inlet (#C2).
• The burning rate can now be lowered by moving the
top air control to the left. For a nominal output, use
the stove with the secondary air at about 80% open.
The airwash system works with the top airslide. When
the top airslide is 80% open the system works at its
strongest efciency.
The more closed down the airslide is, the less effective
the airwash will be (when shut down completely, the
airwash system can not function).
3.2.2. Re-fuelling
• Open the glass door and add logs.
- Open the primary and secondary air settings fully for
a few minutes in order to establish a good re before
closing the promary air and positioning the secondary
air slider to the desired setting.
3.3. Cleaning
It is essential to keep the grate free from a heavy
build up of ashes. The Belfort is equipped with a grate
riddling device which is used to “shake” ashes off the
grate into the ash pan.
Whenever the stove is burning without life when the
lower spin wheel is open, use the riddling lever to clear
the grate of surplus ashes.
REMEMBER TO BURN SOLID FUEL CORRECTLY, AlR
SHOULD BE ALLOWED TO FLOW FROM THE ASH PIT
AREA THROUGH THE GRATE AND THROUGH THE
FUEL. IF THE GRATE OR ASH PAN ARE CONGESTED,
THE PERFOMANCE WILL BE EFFECTED.
If burning solid fuel, always empty the ash pan at least
once a day or whenever it is full of ashes. Never allow
the ashpan to overll allowing ash to be in contact with
the underside of the grate. If this condition is allowed,
the grate will wear out pre-maturely.
3.4. Maintenance of the Chimney
Very important : In order to avoid any incident
(chimney re, etc...), maintenance tasks must be
carried out regularly. If the appliance is regularly used,
the chimney should be swept several times per year,
together with the stovepipe connection section.
If the chimney catches re, you must cut off
the ue draught, close the doors and windows,
hatches and keys, stop up the connection hole
with wet cloths and call the Fire Brigade.
DO NOT OPEN THE DOOR OF THE APPLIANCE
(OR AIR INLET) UNDER ANY CIRCUMSTANCES
Chimney condition should be checked at least once per
year by a professional engineer.
3.5. Maintenance of the stove
• The appliance must be cleaned regularly, together
with the connecting pipe and the ue pipe.
• Remove all deposits from the combustion chamber
and clean the grate area.
• The glass should be cleaned with a solft cloth or
kitchen paper dampened with a mixfure of water and
vinegar or general household glass cleaning spray.
Only clean the glass when the stove is cold and never
use abrasive cleaners or cleaning pads as This will
scratch the ceramic glass.
• The “vitroceramic” glass will resists to temperatures
of up to 750 C. Should the glass break due to misuse,
it must be replaced by the manufacturers own product.
• The external castings Can be cleaned using a soft lint-
free cloth, which Can be used dry or slighty dampened.
In case of any water splashes or condensation marks,
these should be cleaned off before they have chance
to dry out.
• Ensure that the fuel retainer is installed correctly (g.
9).
• Check that there are no obstructions before relighting
after a long period of disuse.
• The appliance must not be used with a ue serving
several appliances.
• Ensure the grate is free from any obstruction and
riddles freely.

Warning ! It is quite normal for enamel surfaces to
have a crackling appearence during the operation of
the stove and these tend to disappear again once the
stove has cooled down. This is natural process which
does not effect the quality of the enamel or the lifespan
on the appliance.
3.6. Recommendations
This room heater is an appliance producing heat and
may cause severe burns if touched.
The stove may still be hot even when re has
burnt out.
