2.1
SITING GENERAL
This fire is suitable for hearth mounting only on a non-combustible hearth at least 13mm thick and measuring at least 630mm wide
by 330mm deep. Its top surface should preferably be 50mm above the floor level in order to discourage the placing of carpets or
rugs over it. It MUST NOT be fitted directly on a combustible wall. The fire should be installed so that no part of a combustible wall
o
i.e. not part of the fire surround but a full wall at 90 to the fire is less than 500mm from the radiant source. If this is not possible the
combustible side wall must be suitably protected.
FIREPLACE OPENING
The front opening of the fireplace must be between 305mm and 457mm wide and between 560mm and 585mm high (see Section
2.2). If the opening is greater it must be bricked up until the opening is a maximum of 585mm high and 457mm wide, alternatively a
non-combustible infill panel may be used to achieve the required dimensions.
DO NOT USE THE BACK OF A FIRE SURROUND OR MARBLE TO ACHIEVE THE ABOVE DIMENSIONS.
There must be a minimum flat surface area around the fireplace opening shown by the dotted lines in fig. 1 to ensure a good seal
between the fireplace and the fire. This area should be sound enough to take the wall plugs and screws supplied for front fixing.
Ensure that the base of the fireplace is level with the hearth and reasonably flat to prevent the fire rocking. Purpose built ventilation
bricks or additional air vents are not normally required in the room in which the fire is fitted unless specified by the rules in force.
IMPORTANT: When fitting any heating appliance or wallpapering a room in which one is fitted, soft wall coverings such as heat
sensitive wallpapers may become heat damaged or discoloured especially in the area above the fire. Please bear this in mind
when installing or decorating.
IMPORTANT NOTE
Plaster Applied Directly to Pre-cast Flue Blocks.
Some Pre-cast flues built to B.S. 1289:1975 may have plaster applied directly to the flue blocks.
A recommendation was made, in the revision B.S. 1289 part 1:1986, NOT to apply plaster directly to the flue blocks, otherwise
cracking of the plaster could occur.
It is not recommended to install this fire into such installations, unless remedial action is taken.

FLUES AND CHIMNEYS
2.2.1 SITE REQUIREMENTS FOR 228mm BY 228mm (9in BY 9in) BRICK CHIMNEY/178mm (7in)
STONE OR LINED CHIMNEY AND 125MM (5in) DIAMETER FLUE
The minimum dimensions for the fireplace opening for a brick chimney are as shown in Fig. 1. It will not normally be necessary to
remove any chair brick provided the minimum depth is obtained. A chimney previously used to burn solid fuel must be swept prior
to installation.
The chimney must be inspected to ensure that:
(a)
It serves only one fireplace.
(b)
It is properly sealed so that combustion products do not escape from the flue into the room.
(c)
It is not blocked by paper, rubble etc.
(d)
Any restriction such as damper, register plate, etc. must be removed or secured in the fully open position.
(e)
Any underdraught ventilation or additional air supply
entering the fireplace or on the hearth must be
sealed off.
(f)
It must have at least 3 metre effective flue height.
(g)
It must have a positive updraught.
CHECK THE FLUE FOR GOOD DRAUGHT
Apply a lighted paper or smoke match to the top of the
opening in the fireplace. Observe if there is a definite flow
into the chimney and if so proceed with fitting the fire.
If no flow is indicated, warm the chimney for several minutes
and then re-check. If downdraught is observed a suitable
terminal must be fitted and the chimney re-checked.
If persistent no-flow or downdraught condition is observed
DO NOT FIT THE FIRE, SEEK EXPERT ADVICE.
