1 INSTALLATION INSTRUCTIONS
1.1 GENERAL
The gas fire must be positioned and connected as a “room sealed system” (balance
flue) appliance by a “Gas Safe Register” registered gas installation engineer in
accordance with the following installation instructions, nationally and locally applicable
regulations (see “Technical Details / Regulations” at the rear of this manual). If you have
any queries regarding the installation, please consult your local gas company.
Important: Before beginning the installation, check that the details on the
rating plate correspond to the gas type and pressure to which
the appliance will be connected.
The appliance is factory set to the correct nominal heat input. The pilot light is set to the
correct level of consumption.
The appliance will be delivered from the factory with a Ø100 mm - Ø150 mm concentric
connection for extracting the flue gases and supply of combustion air.
It is possible to install the gas fire with either a wall or roof outlet.
The roof connection must be carried out using the concentric flue system Ø100 mm -
Ø150 mm. The fumes are exhausted naturally to the outside environment through the
inner Ø100 mm pipe whereas the combustion air supply passes between the Ø100 mm
and Ø150 mm pipes.
The gas fire can be installed in a completely sealed or mechanically ventilated house
without extra ventilation and/or fume extraction.
The gas fire can be installed as an insertion into an existing open fireplace or as
a built-in appliance in a new fireplace.
In order to prevent the fireplace heating up excessively, it must be properly
ventilated by installing vents at the top and bottom of the fireplace.
The appliance is equipped with a convection casing. This brings the heated air into
the room. Optionally, the appliance can be equipped with a convection fan for faster
dissemination of this hot air.
If an existing chimney is to be used, please consult your installer first. If the chimney
was previously used for a wood or coal fire, then it should be cleaned by an expert.

1.2 CONCENTRIC FLUE SYSTEMS Ø100 MM - Ø150 MM
• Bellfires - Muelink & Grol system
• Poujoulat - DUOGAS system
• Ontop - Metaloterm US system
• Jeremias/STB - H-Twin system (STB = Chimney-Technics
Brummen NL)
• Jeremias - TWIN-GAS system
The gas fire, in combination with the concentric flue system [Ø100 mm - Ø150 mm]
(rigid and/or flexible)
for the brand types mentioned above, has been approved in
accordance with the European CE-norm for gas appliances and may therefore be used
only with these systems.
The permitted components for these systems are listed in instructions enclosed:
AVAILABLE COMPONENTS CONCENTRIC FLUE-SYSTEMS FOR BELLFIRES GAS
FIRES WITH CLOSED COMBUSTION SYSTEM. The guarantee on the
appliance lapses if it is installed, fully or partially, with other components or a different
flue system.
The concentric flue [Ø100 mm - Ø150 mm] systems can be used with either a
newly-built or existing chimney.
N.B. If any part is missing, please contact your dealer.

1.5 PREPARATION FOR INSTALLATION
The following preparation must be carried out before the gas fire can be installed.
1.5.1 Instructions for positioning the outlet
1.5.1.1 Positioning the outlet for correct operation:
Roof-mounted outlet:
Figure 1: Roof-mounted outlet
This must be positioned at least 0.5 m from the roof edge;
the apex of the roof can be disregarded.
Wall-mounted outlet:
Figure 2: Wall-mounted outlet
This must be positioned at least 0.5 m from:
• the corner of the building.
• the roof overhang, the rain gutter.
• balconies etc., unless the exhaust construction
extends to at least the face of the protruding section.
>0.5 m
>0.5 m

1.5.1.2. Positioning the outlet to avoid affecting the surrounding area
All listed “distances” in this section are no more than
guidelines.
For the exact minimum “distances”, please consult your
national and local directives.
“Distance” = minimum distance required for positioning of the outlet to avoid
adverse effects with respect to:
A. A ventilation opening serving an occupied room, a toilet or a bathroom.
B. A heating air supply, when the supply flows through an occupied room.
C. A window that can be opened and that is near an occupied room, a toilet
or a bathroom.
Roof-mounted outlet:
To avoid adverse effects Distance: outlet - A, B or C
At the same roof level. >3 m (*)
At a different roof level. >1 m (*)
At a lower positioned wall. >1 m
At a higher sloping surface. >3 m (**)
(*) If the required distance cannot be achieved, the outlet position rules take
precedence.
(**) If the required distance cannot be achieved, the position of the outlet must
be at least 1 m above the highest facade/roof.

Bellfires English
Installation instructions
Wall-mounted outlet:
To avoid adverse effects Distance: outlet - A, B or C
At walls in buildings with staggered Not permitted if A, B, or C are located
heights. above the outlet.
On a wall - general. (*) Above the outlet: >2 m
Below the outlet: >0.75 m
Left and right of the outlet: >0.75 m
At <1 m from the roof overhang. >2 m
Beneath balconies, walkways etc. >2 m from the underside of the
protruding balcony or walkway.
Beneath balconies, walkways >2 m
etc. where the outlet extends to
the front.
To the garden or on the terrace. >2 m to the outside space. (**)
With respect to a facing wall. >2 m (if the distance from the facing
wall is less, the criteria detailed for
“On a wall - general” apply).
Enquire at your local gas company for the regulations relating to outlets
positioned opposite each other and outlet(s) in facade(s) that form an angle.
(*) These minimum distances do not apply if there is an obstruction
between the outlet and A, B and C that protrudes at least 0.5 m from
the wall and has a length exceeding the distance.
(**) This distance is not required if the outlet is situated at least 1 m
higher than the intended area of the outside space.
If the outlet has a clearance of less than 0.5 m from the hard surface of a public area at
a height of less than 2 m, it must be fitted with an effective protector. The mesh size of
the guard must not affect the correct operation of the appliance.

1.6 GENERAL SERVICES
1.6.1 The Fume Channel/Combustion Air Intake
The combined fume channel and combustion air intake requires one of the following
concentric flue system configurations.
Important: Due to the high temperature of the outer walls
(approx. 150°C), no flammable materials may be located
or used in the vicinity of the flue system.
The complete flue system, must therefore be sleeved
with a heat resistant material after assembly.
Ventilate the covered concentric flue by fitting a
grid near the floor and ceiling (on each floor).
Do not insulate the concentric flue.
Use the universal wall/floor support Ø150 mm
to attach the covering of the concentric flue system
[Ø100 mm - Ø150 mm], see 1.6.2, drawing number 36.
Use as a wall support Use as a floor support
