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 6461 Part 1 Installation of Chimneys and flues

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 only be installed on a hearth it must not be installed directly onto
carpet or other combustible floor materials.

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
overhang 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.

5. Using a smoke pellet, check that there is an up-draught in the

chimney / flue and that the smoke can be seen issuing from the
terminal / chimney pot outside.
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.

6

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 400 and 450 mm wide, and
between 550 and 570mm 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.

For example, if the appliance was to be fitted into a 400mm wide opening, the
depth required would be 298mm. See figure 2 below for explanatory diagram.

1.7 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 / BS EN 1856-2, (for example the Selkirk
LFE 175 box). The box must have a minimum flue diameter of 175mm internal
and minimum internal dimensions of 300mm deep by 580mm high by 400mm
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.

1.8 HEARTHS

This appliance must only be installed on to a concrete or non-combustible hearth.
The hearth material must be a minimum thickness of 13mm with the top surface at
least 50mm above the floor. The hearth must be fitted symmetrically about the fire
opening and have a minimum width of 760mm and a minimum projection of
300mm forwards from the fire opening.

1.9 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) The spillage monitoring system must not be adjusted by the installer.

2) The spillage monitoring system must not be put out of operation.

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.
