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 / metal flue boxes conforming to BS 715. All flues must con-
form 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
The efficiency baffle must be fitted when installing this product into a
conventional brick built chimney , to prevent debris falling onto the fuelbed.
If fitting into a class 1 (175mm) metal flue box and liner, it is desirable to leave the
baffle in place to reduce the flue flow and thus increase the heat output from the
appliance. Safe clearance of products must always be checked by carrying out a
smoke match test as described on page 21.

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 150
oc.
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 fire surround. 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 (e.g. wooden) 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.
5

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 433mm and 444 mm wide,
and between 568 to 573mm 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 fig.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.

being installed into a brick built chimney , requiring 12.0 litres of debris
collection volume.
When installing this product into a builders opening / brick-built chimney , the depth
required is a minimum of 323mm. This fire is not suitable for use in fireplaces
fitted with an existing chairbrick. The chairbrick must be removed to give the
required clearances. The fireplace must be checked to ensure that no rear part of
the fireplace opening is within 50mm of the flue outlet of the fire when installed.
For example, if the appliance was to be fitted into a 433mm wide opening, the
depth required would be 323mm. See fig. 2 below for explanatory diagram.

1.9 SPILLAGE MONITORING SYSTEM
This appliance is fitted with an atmosphere sensing spillage monitor-
ing 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
