Fireplace Opening
IMPORTANT NOTE: This appliance DOES NOT seal onto a marble or stone back panel. The fire is installed directly into the
FIXING PLATE assembly. Installaon of this fixing plate is detailed on the preceding pages 5,6 & 7.
The mantel should be constructed to the requirements shown on the preceding pages 8,9 & 10.
The fireplace opening should be checked to ensure it meets the dimensional specificaons stated in the diagrams above. It
is also important that the area surrounding the fireplace opening is flat and vercal. If the surface surrounding the fireplace
opening is not flat and vercal then the wall should be remedied prior to the installaon taking place.
The FIXING PLATE (or precast spacer—if applicable) will fit against this fireplace opening, see pages 5, 6 & 7 for installaon
opons. If the fireplace opening is outside these dimensions then the opening should be made good to these dimensions
using a suitable non-combusble material before proceeding.
A flat surface of a minimum 800mm wide and 800mm high must be provided around the fireplace opening to ensure a
good seal is formed between the FIXING PLATE / PRECAST SPACER and the wall. In addion 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 installaon of the
appliance.
The minimum hearth dimensions are shown in the diagrams on pages 8 and 9. The upper surface of the hearth must be a
minimum of 50mm above the floor and the fireplace opening should be filled with a suitable non combusble material to
bring it level with the hearth.
Installaon 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 collecon void should be capable of accommodang twelve (16.5) litres of
volumetric space. The flue height must be a minimum of 3 metres.
Installaon 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 effecve 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 insulaon or similar.
The metal flue box (to BS715) must stand on a non-combusble surface with a minimum thickness of 12mm.
Installaon into a PRE-CAST FLUE Installaon
Ensure that there is a minimum of 115mm from the front of the fireplace opening to the rear of the flue starter block—this
is to ensure that sufficient clearance is allowed for debris collecon. The flue height must be a minimum of 3 metres.
