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 940mm wide and 700mm 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.
Installaon 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.
Installaon 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.
Installaon into a PRE-CAST FLUE Installaon
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.
