INSTALLATION REQUIREMENTS
1.1 CONDITIONS OF INSTALLATION
It is the law that all gas appliances are installed only by a GAS SAFE registered
Installer, in accordance with these installation instructions and the Gas Safety
(Installation and Use) Regulations 1998 as amended. Failure to install appliances
correctly could lead to prosecution. It is in your own interest and that of safety to
comply with the law.
The installation must also be in accordance with all relevant parts of the Local and
National Building Regulations where appropriate, the Building Regulations
(Scotland Consolidation) issued by the Scottish Development Department, and all
applicable requirements of the following British Standard Code of Practice.
1. BS 5871 Part 2 Installation of Inset Live Fuel Effect Gas Fires
2. BS 6891 Installation of Gas Pipework
3. BS 5440 Parts 1 & 2 Installation of Flues and Ventilation
4. BS 1251 Open fire place components
5. BS 715 / BS EN 1856-2 Metal flue pipes for gas appliances
6. BS EN 1858 Clay Flue Blocks and Terminals
7. IS 813 : 1996 Domestic Gas Installation (Republic of Ireland)
No purpose made additional ventilation is normally required for this
appliance, when installed in G.B. When Installing in I.E. please consult
document I.S. 813 : 1996 Domestic Gas Installation, which is issued by the
National Standards Authority of Ireland. If installing in Northern Ireland,
please consult local building regulations. Any purpose made ventilation
must be checked periodically to ensure that it is free from obstruction.
1.2 FLUE AND CHIMNEY SUITABILITY
This appliance is designed for use with conventional brick built or lined chimneys
and fabricated flues and metal flue boxes conforming to BS 715 / BS EN 1856-2.
All flues must conform to the following minimum dimensions.
Minimum diameter of circular flues 125 mm (Without Flue
Restrictor Fitted)
Minimum effective height of all flue types 3 metres
When fitting to conventional chimneys or 175mm flues it may be desirable to
fit the flue restrictor baffle (supplied) to reduce the flue flow and increase the
efficiency of the fire. Safe clearance of products must always be checked by
carrying out a smoke match test as described.

5
1.3 FIREPLACE / SURROUND SUITABILITY
The fire must not be installed directly onto carpet or other combustible floor
materials. See page 9 for further details regarding hearth panels.
The fire is suitable for fitting to non-combustible fire place surrounds and
proprietary fire place surrounds with a temperature rating of at least 150oc.
If a heating appliance is fitted directly against a wall without the use of a fire
surround or fire place all combustible material must be removed from behind
the trim. Soft wall coverings such as blown vinyl, wall paper etc. could be
affected by the rising hot air and scorching and/or discoloration may result.
Due consideration should be made to this when installing or decorating.
1.4 SHELF POSITION
The fire may be fitted below a combustible shelf providing there is a minimum
distance of 200mm above the top of the fire and the shelf does not project more
than 150mm. If the shelf overhangs more than 150mm the distance between the
fire and the shelf must be increased by 15mm for every 25mm of additional over-
hang over 150mm.
1.5 FLUE / CHIMNEY INSPECTION
Before commencing installation, a flue or chimney should be inspected to ensure
that all the following conditions are satisfied.
1. Check that the chimney / flue only serves one fire place and is clear of any
obstruction. Any dampers or register plates must be removed or locked in
the open position.
2. Brick/stone built chimneys or any chimney or flue which has been used for
an appliance burning fuel other than gas must be thoroughly swept. The
base of the chimney / flue must also be thoroughly cleared of debris etc.
3. Any under-floor air supply to the fire place must be completely sealed off.
4. Ensure that the inside of the chimney / flue is in good condition along it’s
length and check that there is no leakage of smoke through the structure
of the chimney during and after the smoke pellet test. With pre-cast flues
it is especially important to check the inside of the flue for extruded
cement / sealant protruding from the joints between the flue
blocks. If present, these should be removed by rodding the flue
before proceeding with the installation.
5. Using a smoke pellet, check that there is an up-draught in the chim
ney / flue and that the smoke can be seen issuing from the terminal /
chimney pot outside.

6
There must be no leakage of smoke through the structure of
the chimney during or after the smoke pellet test and it is
important to check inside upstairs rooms adjacent to the chimney /
flue. Check the chimney pot / terminal and general condition of the
brickwork or masonry. If the chimney or flue is in poor condition or if
there is no up-draught do not proceed with the installation. If there is a
history of down-draught conditions with the chimney / flue, a tested and
certificated flue terminal or cowl suitable for the relevant flue type should
be considered.
6. A spillage test must always be carried out during commissioning of
the appliance.
1.6 FIRE PLACE OPENING AND CHIMNEY CATCHMENT SPACE
The front opening of the fire place must be between 350mm and 400mm wide,
and between 490 and 500mm high. If the opening exceeds these dimensions then
a surround must be constructed from suitable non-combustible material to produce
a correct size opening. Any surround must be suitably sealed to the fire place to
prevent leakage. See below in figure 1.

When installing into a brick built chimney, you must ensure that there is sufficient
depth to accomodate any debris which may fall from the chimney. This depth
must be sufficient to accomodate 12 litres of volumetric space.

installed into a brick built chimney, requiring 12.0 litres ofdebris collection
volume (figure 2).
The chimney requires a minimum of 50mm clearance when measured from the
mouting face of the fire behind the firebox to accomodate 12.0 litres of debris
collection.
See figure 2 below for explanatory diagram.

1.7 FITTING TO FIREPLACES WITH EXISTING CHAIRBRICKS AND
CONVENTIONAL BRICKBUILT CHIMNEYS
This appliance is suitable for use in fireplaces fitted with an existing chairbrick
without the need for removal of the chairbrick, providing the minimum depth of the
fireplace from mounting face to chairbrick exceeds 125mm. The fireplace must be
checked to ensure that no part of the chairbrick is within 50mm of the flue outlet of
the fire when installed.

8
1.8 FITTING TO PRE-CAST FLUE INSTALLATIONS
To install the fire box in to pre-cast flue starter blocks, there must be at least
100mm from the mounting face of the fire to the rear of the pre-cast flue
starter block to allow sufficient space for debris collection. It is important to
consider this depth if choosing a fire surround as the thickness of the fire surround
must be sufficient to give a total depth of at least 100mm to the rear of the
starter block, otherwise there will be insufficient depth. To increase this depth the
fire surround may be packed away from the wall using suitable non-combustible
board, providing the installation is correctly sealed. If in doubt about the suitability
of the fire contact Formosa Fires for advice before proceeding.
It is important to ensure that the pre-cast flue is in good condition and is free from
extruded mortar or sealant from between the flue blocks.
This appliance has been tested for use in a pre-cast flue block complying
with BS EN 1858. In accordance with BS EN 1858, pre-cast flues built with
directly plastered faces (front or rear) are not correctly installed as to ensure
proper operation with any type of gas fire. In some instances of this flue
construction, temperature cracking of surface plaster may occur through no
fault of the appliance. An air gap or some form of insulation material should
be installed to prevent normal flue temperatures from damaging wall
surfaces.
1.9 FITTING TO PRE-FABRICATED TWIN WALL METAL FLUE BOXES
The appliance may be fitted to twin wall metal flue boxes conforming to the
constructional requirements of BS 715, (for example the Selkirk LFE 125 box).
The box must have a minimum flue diameter of 125mm internal and minimum
internal dimensions of 160mm deep by 490mm high by 350mm wide. There are
no maximum dimensional requirements for the box. The top face of the box must
be insulated with a minimum thickness of 50mm of non-combustible mineral wool
insulation or similar material. The flue box must stand on a non-combustible base
of minimum thickness 12mm.

9
1.10 WALL / HEARTH MOUNTING
This appliance must be fitted on a flat, non-combustible base of minimum
thickness 12mm. In addition, a non-combustible hearth or physical barrier should
be provided in front of the fire.
With “hole in the wall” type installations, where it may be desirable not to fit a
hearth panel or physical barrier, the product may be installed in accordance with
Document J of the building regulations so that every part of theflame or
incandescent material is at least 225mm above the floor level. For the customers
safety, and in accordance with BS 5871-2, the fitting of a hearth panel or physical
barrier should be carried out. Should this advice not be followed however, please
give consideration to the safety of the occupants in the room to which the
appliance is installed.
Any hearth panel or physical barrier that is fitted should project a mnimum of
300mm forwards from the fire opening and 150mm either side of the fire
opening, as shown below in figure 3. Any physical barrier must be securely fixed
and be of robust design.

1.11 SPILLAGE MONITORING SYSTEM
This appliance is fitted with an atmosphere sensing spillage monitoring system in
the form of an oxygen sensing pilot. This is designed to shut the fire off in the
event of a partial or complete blockage of the flue causing a build up of
combustion products in the room in which the fire is operated. The following are
important warnings relating to this spillage monitoring system :-
1.11.1 The spillage monitoring system must not be adjusted by the installer.
1.11.2 The spillage monitoring system must not be put out of operation.
1.11.3 When the spillage monitoring system is exchanged only a complete
original manufacturers part may be fitted. It is not possible to replace
individual parts on the pilot system on this appliance, only a complete
pilot assembly (including the thermocouple) may be fitted.
