Installation Instructions
SECTION EIGHT
Siting the Appliance
The fire can be installed in the following locations: -
CLASS ONE & CLASS TWO & PRE-CAST
A conventional brick or stone chimney as used for a solid fuel appliance with an effective cross-
sectional dimension of 225 x 225 mm (9 x 9 INS) or a clay/ceramic/metal lined flue with a minimum
diameter of 125mm (5 INS). A prefabricated gas flue system with a minimum diameter of 125mm (5
INS). The chimney should be swept prior to installation if previously used with solid fuel or oil
appliances. It is not necessary if the flue is new or previously used with a gas appliance. The chimney
to have a minimum effective height of at least 3 metres. Any permanent flue restriction or variable
dampers are to be removed or locked fully open.
A pre-cast flue correctly constructed conforming to the requirements of BS 1289: 1975, 1986 or 1989
with a minimum effective overall height of 3 metres (10 ft) which is correctly terminated (see BS
5440). It will normally require an additional thickness of 25mm in the form of a fireplace back panel or
if it is intended to be fitted back to the plaster line then a spacer may be required to meet with the
minimum depth requirement.
I
MPORTANT
: - The flue restrictor is made up of 3 snap-
off plates and needs to be removed for 5”
and pre-cast flues
Note: An inspection should be made to ensure that the internal walls of the flue are clear of mortar
fangs. It is recommended that the plasterwork should not be directly bonded to the surface of the flue
blocks, ensuring that there is a small air gap between the flue blocks and the wall surface. The fire
can be installed with the plasterwork being directly bonded to the flue blocks but there is a risk of
surface cracking occurring to the plaster above the appliance.
INSTALLATION REQUIREMENTS INTO THE FIREPLACE
The front face and the base of the fire opening must be
flat to ensure that a good seal is formed between the rear
and base of the appliance and the chimney to avoid any
reduction of natural draught. A minimum depth of 170 mm
is required into the fireplace if the chimney has previously
been used with solid fuel or oil appliances. A minimum
depth of 140 mm is required into the fireplace if the
chimney is new or has only been used with gas fires
previously. If insufficient depth is found, spacer frames
can be obtained from the manufacturer to increase
installation depth (see diagram).
HEARTHS
The fire can be fitted in either a conventional hearth see diagram (I.E Tile fireplace etc), or plinth
mounted, as a hole-in-the-wall installation
HOLE IN THE WALL
The fire may be installed without a traditional fireplace, if it is installed this way, ensure the base of
the fire opening is at least 50mm (2”) from the floor surface. It will also be necessary for a non
combustible shelf or plinth to be provided to support the fire front, A suitable shelf or plinth would
need to project from the fixing plain of the fire a minimum of 100mm and be at least as wide as the
appliance (505mm)
IMPORTANT NOTE when the fire is installed without a fireplace or non combustible back panel any wall
surface or covering that comes in contact with the appliance and is not non combustible must be removed.
PURPOSE BUILT HEARTH AND SURROUND
Purpose built superimposed fire-resistant hearths and back panels, specified as suitable by the
manufacturers, may be used, or a suitable proprietary fire surround with a 150
o
C minimum rating.
