1. INTRODUCTION
1.1. FOREWORD
We would like to congratulate you on your purchase of this modern Bellfires built-in
wood fire. This quality product will give you years of heating pleasure as you enjoy the
play of the flames and the cosy glow of the fire.
This manual contains directions for both positioning the appliance and for its
environmentally-friendly use. It also contains technical data for the appliance, parts
information and directions in the event of problems. Study this manual carefully before
using the stove. We recommend you keep this manual in a safe place for reference
purposes.
1.2. SAFETY AND INSTALLATION INSTRUCTIONS
Safety
Do not place flammable objects within 150 cm of the appliance. Pay special
attention to furnishings and ornaments around the fire.
When you use your fire, the exterior will become hot. Always wear the glove or use
the accessories supplied when filling etc. Protect yourself and others (especially
children!) from burns. Do not leave children unattended when the fire is burning.
Watch your clothing. Synthetic clothing in particular can easily catch fire and burn
intensely.
Do not approach the appliance with flammable materials or liquids. Any work with
solvents, adhesives etc. in the space heated by the fire can be very dangerous.
Make sure you know what state your chimney is in. Cracks in the chimney may not
only lead to damp, staining of walls and leaking of smoke, they can also impair the
carrying off of smoke. Make sure you get proper advice from your Bellfires dealer
or other specialist company.
Avoid chimney fires! Have your chimney swept at least once per year - more often
if you use your fire a lot. Prevent excessive deposits of soot inside the chimney by
not burning freshly-cut wood. Instead, burn clean, dry chopped wood.
Do not use your built-in fire as a barbecue. This can cause (flammable) fat deposits
to be left in the chimney and hastens the chimney becoming clogged. Prevent your
chimney being soiled from above (birds’ nests etc.) by fitting a suitable cap to the
chimney pot.

Instructions for use and installation instructions
Follow the instructions issued by your local fire brigade.
The fire can be taken in operation if national and local regulations are satisfied. The
required constructive adaptations should be satisfied as well.
Installation instructions
Wood and wood briquettes may be stoked in the fire.
Coals can’t be burned in the fire, because of the absence of a grid/ridling grill.
Never use the appliance to burn rubbish.
Please read all instructions/stickers on and around the appliance.
Please also study the directions for use before using the appliance for the first time.
When you first fire up your appliance, there are a number of extra points you should
take into account. See chapter 6.
In transit, some parts of the appliance may have moved from their original place.
The Slide Bell is a built-in fire with lift door. Check that the door opens and closes,
the retardant plates (brake plates) are fitted correctly to the brackets at the top of the
fire, the interior panels are fixed to the walls and the stones on the bottom have not
moved.
Avoid over-loading (white burning glow), caused, for example, by lengthy burning
with a fully open primary air vent, or by burning too much wood in one go.
The fire can then become over-heated.
The appliance may only be set up if the appliance and location meets the
- national and local installation regulations;
- local fire brigade regulations and required architectural provisions.

2.3. BASIC REQUIREMENTS FOR POSITIONING BUILT-IN FIRES
General.
The appliance may only be set up in a room in which the location, architectural
construction and activity is not endangered by the presence of a fire. The surface on
which the appliance is to be placed must be correctly shaped and big enough to
accommodate the appliance safely (in compliance with DIN 18895, part 1).
When fitting, all local and/or national safety regulations must be followed closely,
particularly in rooms with walls/floors containing flammable material. If in doubt, consult
the fire prevention department of your local fire brigade and/or the architectural depart-
ment of your local authority.
Built-in fires may solely be used in:
Rooms with at least one outer door or window that can be opened.
A suite of rooms connected directly or indirectly with each other with a collective
supply of air.
In the aforementioned cases, the capacity of the room(s) must be at least 4 m³ per kW
of nominal output.
Built-in fires may only be constructed or moved into rooms where at least
360 m3combustion air per hour and per m2clear fire opening can circulate. If there are
any other fire-burning appliances in the same room, at least 540 m³ combustion air per
hour and per m² clear fire opening must be in circulation.
Other appliances must have at least 1.6 m³ combustion air per hour, per total nominal
output in kW at a calculated pressure difference of 0.04 mbar with the ambient air.
Built-in fires must not be used in:
Staircases, except in buildings with no more than two apartments.
Entrances providing general access.
Rooms in which highly inflammable or explosive substances are processed or
manufactured.
Garages;
Rooms or apartments with air conditioning or convection heating provided by fans,
unless it can be guaranteed that they will not interfere with the working of the fire.
This is under the following conditions:
the installation merely circulates air around the room;
the installation has sufficient safety provisions preventing the possibility of
spontaneous and automatic underpressure being created in the room in
which the fire is situated;
www.tapis.pl

14
Bellfires English
Instructions for use and installation instructions
that the combustion air stream created by the fire and the volume streams
of the extraction installations in the room and adjoining rooms connected by
de-aeration connections do not create underpressure greater than 0.04 mbar.
This must also be guaranteed if easily accessible air-conditioning equipment is
moved or removed from the room.
Provision of combustion and convection air
The local chimney sweep/authorities must be consulted prior to fitting regarding the
suitability and combustion air supply. DIN 18160 must be observed. DIN 18895 parts 1
and 3 also apply.
Built-in fires may be fitted with an air pipe supplying air from outside (this is mandatory
in Germany). The air supply should have an opening of at least Ø125 cm and the air
pipe should be fitted with an adjustment valve; the position of the valve should be
visible from the outside.
The air supply in thus refreshes the air in the room and is also used in the combustion
process. As this air runs through the convection system, it is also referred to as ‘pre-
warmed combustion air’.
The casing / fireplace
The casing may not be directly connected to the built-in fire, but must be constructed
so that it is self-supporting; a mantle iron or lintel should be used for this. The
covering in the area must be of non-flammable materials of flame-retardant material
class A1. This includes bricks, cladding, ceramic tiles, metal or plasterwork,
Promatec and Nobranda.
The opening for incoming and outgoing air from the casing must be at least totally
900 cm². At least 200 cm² from the opening for incoming and outgoing air must not
be closable.
The ventilation of the casing/fireplace can be provided by grills, but this can also be
achieved by not building the fireplace right up to the ceiling (leaving a gap of 5 cm).
www.tapis.pl

15
Bellfires English
Instructions for use and installation instructions
If desired, when building in the fire, all connection pieces (convection set 1x or 2x)
for warm air can be connected to the convection casing. If separate connection
adapters are closed, the manufacturer cannot guarantee the evenness of the
temperature of the air and air speed.
Figure 1: Use of convection set and ventilation of fireplace
www.tapis.pl

16
Bellfires English
Instructions for use and installation instructions
The convection air pipes must be made of non-flammable material which cannot be
distorted.
Within a range of 30 cm either side and 50 cm above the escape opening, there
must be no flammable materials (e.g. wooden ceiling, fitted furniture).
The convection casing of the built-in fire must be covered all around with a 10-cm
thick layer of insulation (use of ceramic wool is permitted).
2.4. CONSTRUCTION REQUIREMENTS
Built-in fires must be constructed such that the adapter from the chimney and
convection pipes can easily be cleaned.
There must be no electrical cables or gas pipes in the walls surrounding the area of the
fireplace.
In accordance with construction regulations (in Germany), combustion air pipes in
buildings with more than two inhabited floors containing piping and cabling running
through fire walls must be fitted in such a way that fire and smoke cannot escape to
other floors or rooms.
2.5. HEAT-INSULATING MATERIALS
The heat-insulating materials to be used must meet specific quality standards.
Manufacturers of insulating materials quote an insulation number on the packaging
consisting of 10 numbers in accordance with the stipulations of AGI-Q132. Only those
insulating materials listed in the adjacent table 1 or alternatives approved (in Germany)
by DIBT may be used.

2.6. CHIMNEY
Every fire needs its own chimney. Several connections to one master chimney, such as
encountered in Germany, is permissible solely when the fire runs with an automatically
closed door. The built-in fire must then be self-closing (in compliance with Bauart 1)
(Optional!). Ensure that any existing chimney is completely air-tight and in good
condition. It must be suitable to accommodate the appliance in question. Make sure
your chimney has a proper cap to prevent rain getting in and birds nesting on it.
The draught in your chimney determines how your fire will burn. The recommended
draught is approx. 15 Pa (0.15 mbar). Your chimney should be at least 4 metres tall
from the point at which the chimney connects to the fire. Chimneys which are well-
insulated measuring in excess of 8 metres can develop a significant draught if the fire is
raging. We therefore advise you to fit a chimney valve or draught diverter between the
fire and the chimney.
2.6.1. Chimneys Slide Bell series
Ensure that any existing chimney is completely air-tight and in good condition. The
diameter of the entire chimney, including the chimney pot on the roof must be at least
Ø200 mm for the Slide Bell 70-55, 70-65 and 90-45; and Ø250 mm for the Slide Bell
80-65 and 105-45.
If there is no suitable chimney immediately available, we advise you to use double-
walled insulated stainless steel pipe sections. Achimney must be compliant with the
prevailing planning conditions. Have a specialist carry out the building. When
purchasing such pipe sections, we advise you to find out whether some form of casing
of the pipes is required.
Afew points for your attention:
Chimneys must be free-standing, i.e. they must not rest on the appliance itself.
All connections between the appliance and the chimney must be properly insulated.
Flammable material must be kept clear (outside the casing/insulation zone) of all
through-feeds in the floor or wall (remember the roof decking).
Do not make any horizontal connections. Deposits and soot will collect here (unless it is
a short horizontal connection directly behind the built-in fire).
The chimney calculation, as in Germany, is made according to DIN 4705 parts 1 and 2
with each of the following measured values:
- mass flow of the flue gasses;
- temperature of the smoke outlet on the fire;
- chimney draught;
- nominal power output.

3. INSTALLATION INSTRUCTIONS
3.1. REQUIREMENTS RELATING TO THE USE OF EXISTING CHIMNEYS
The adapter material for the connection with the chimney must be made of at least
2 mm thick sheet steel and must be insulated with a heat-resistant material 3 cm in
thickness. Connect the pipes to the existing chimney using a sliding sleeve in the
ceiling (niche pipe). Check all connections for air-tightness. If the smoke outlet leads
through parts containing flammable material, such as walls, the adapter must be
encased in at least 20 cm of a mineral substance (such as aerated concrete).
Protection of the basic surface (surface)
When fitting a built-in fire on a surface containing flammable material, the surface must
be fitted with a covering layer of a non-flammable material such as concrete with a
thickness of 6 cm. The concrete plate must be of sufficient dimensions to act as a
bearing surface. The concrete plate must then be covered with at least 3 cm of heat
insulation.
Protection of the floor, in front of the built-in fire/fireplace
The floor, in front of the built-in fire/fireplace must be made of non-flammable material.
The minimum dimensions of these non-flammable surfaces must be as follows.
At the front, the dimensions are determined by the height of the heating area
measured from the bottom plate (h) plus 30 cm (h+30 cm), however no less than
50 cm.
At the sides, the dimensions are determined by the height of the heating area
measured from the bottom plate (h) plus 20 cm (h+20 cm), however no less than
30 cm.
Construction parts containing flammable substances or material and fitted
furniture within the radiation area of the fitted fireplace
Any flammable materials should be kept outside an imaginary circle with an 150 cm
radius centred on the built-in fire.
Ceiling above the built-in fire/fireplace
If the hollow space above the fire reaches as high as the ceiling, it must be protected if
it contains any flammable material and/or if it is a bearing structure. Such protection
should be in the form of a 10-cm thick heat-insulating layer.
Construction parts containing flammable substances or material and fitted
furniture outside the radiation area of the fitted fireplace
There must be a distance of at least 5 cm between the outside surfaces of the fireplace
into which the hearth is built and the construction parts of inflammable building material
and inflammable components, such as integrated furniture.

Instructions for use and installation instructions
Expansion seams
Between the fire and its casing/fireplace, an expansion seam must be factored in to
calculations. This may be filled in with ceramic or fibre-glass sealing tape.
The casing/fireplace must also be covered on the inside with a layer of insulation
material. It is not necessary to insulate the casing if the fitted fireplace is designed so
that the free surfaces thereof cannot get hotter than 85°C.

4. FITTING THE FIREPLACE
4.1. PREPARATION / INSPECTION OF FUNCTION
Remove the transport security, see chapter 2.2
Check the function of the lift door.
Check that the air sliders are in working order.
Check the position of the retardant plates (brake plates).
Check whether the convection holes Ø125 mm (4x) on the top side are open.
Check that the fan, once fitted, is in working order.
Positioning of the fireplace
The fire must be positioned on a concrete surface. If such a surface is not immediately
available, a pedestal must be built from the creeping space.
The appliance can be placed in position using the carrying brackets supplied.
Positioning the Slide Bell without a fan
The space between the fireplace (hearth surround/brick work) and the fire itself should
be left completely open so that there is an empty space.
At least 25 cm of free space should be left on both sides of the fire. This will mean that
the installation of a fan set is always possible.
Ventilate the fireplace, by placing ventilation openings at the top and bottom of the
chimney breast.
The total ventilation openings should be at least 450 cm2at the bottom of the chimney
breast and also at least 450 cm2at the top of the chimney breast.
