SITING THE APPLIANCE
Fireplace Opening
IMPORTANT NOTE:
This appliance
DOES NOT
seal onto a marble or stone back panel. The fire is installed directly onto the
FIXING PLATE assembly. This is detailed on pages 6 & 7.
This FIXING PLATE is also used to support the
marble or stone back panel
. This back panel should have the following cut-
out :
WIDTH 560mm—580mm HEIGHT: 585mm—605mm
A non-combustible fireplace back panel is required with a temperature rating of at
least 150
o
C
. (This is also known as
CLASS”O” - If in doubt please contact the supplier of the back panel to check suitability). It is recommended that the back
panel be constructed of 3 sections with joints across the upper level of the fireplace opening to allow for expansion and
contraction. This back panel should then be bonded to form a single piece using a suitable substrate. The installation of this
appliance into an unsuitable back panel, where this component subsequently cracks, will not be deemed to be a fault of the
appliance.
The fireplace opening (
NOT THE BACK PANEL
) must be between 405mm and 460mm wide and between 565mm and
590mm high. The FIXING PLATE supplied will fit into this fireplace opening and prepare the installation. If the fireplace
opening is outside these dimensions then the opening should be made good to these dimensions using a suitable non-
combustible material before proceeding. A flat face of a minimum 630mm wide and 630mm high must be provided around
the fireplace opening to ensure a good seal is formed between the FIXING PLATE and the wall. In addition it is important to
ensure that the base of the fireplace opening is flat and level with the hearth surface to ensure a secure and aligned
installation of the appliance.
The minimum hearth dimensions are shown in the diagram above. The upper surface of the hearth must be a minimum of
50mm above the floor and must protrude a minimum distance of 375mm out from the fireplace opening.
Installation into a Brick Chimney
When the appliance is being installed into a brick chimney there must be sufficient depth behind the appliance to
accommodate any falling debris. This debris collection void should be capable of accommodating twelve (12)litres of
volumetric space. The appliance will require a debris collection space behind the firebox of 39mm (total depth of 169mm)
to achieve this if the fireplace opening is 400mm. If the fireplace width is 460mm wide this clearance can be reduced to
17mm (total depth of 147mm).
Installation into a Prefabricated Twin Wall Metal Flue Box
This appliance can be installed into a prefabricated metal twin wall flue box providing it complies to the requirements of
BS715 / BS EN 1856-2. The box must have an insulated flue with a minimum diameter of 125mm (5”) diameter and a
minimum effective overall height of 3 metres.
The top outer face of the flue box should be insulated to prevent heat loss with a layer of mineral wool insulation or similar.
The metal flue box (to BS715) must stand on a non-combustible surface with a minimum thickness of 12mm.
