PREPARATION OF THE FIREPLACE OPENING
The appliance must be installed mounted on a non-combustible hearth. It must not be installed
directly on any combustible material. The hearth must be at least 12mm thick with a periphery
thickness of at least 50mm. It should be at least 700mm wide and project at least 300mm for-
wards from the fire opening.
The appliance must be fitted into a non combustible opening.
The area around the fire opening (where the appliance side and top flanges meet it) should be
reasonably flat to ensure a good seal. If necessary, take appropriate measures to ensure this.
The floor within the fireplace opening should be reasonably flat to ensure a good seal can be
made at the bottom of the appliance.
Any underfloor air supply to the fire opening must be sealed off completely.
The appliance can be fitted with a non combustible fireplace surround or a proprietary fireplace
surround with a temperature rating of at least 150°C.

increase by 15mm for every additional 25mm of projection beyond 150mm.
