Hole-in-the-wall installations
Where the appliance is to be installed as a hole-in-the-wall fireplace, a hearth as previously
detailed for floor level fireplaces shall be fitted on the floor beneath the hole so as to
protect combustible material from heat.
However, if a hearth is not to be used, so as to maintain a minimal and contemporary
look, the appliance must be installed so that every part of any naked flame
or incandescent part of the fire bed is at least 300mm vertically above any
carpet or floor covering.
When no hearth is to be fitted consideration must be given to fixing a tactile barrier to protect young
children, the elderly and the infirm.
A tactile barrier can be in the form of a fender, kerb, hearth, shelf or horizontal bar all made from non-
combustible material and fixed not less than 50mm & not more than 1000mm above the floor level.
They should be positioned not less than 300mm in front of the appliance.
This appliance can be fitted into a number of flue boxes provided that the minimum dimensions
required for the appliance complied with. The frame of the fire, any back panel or other infill panels,
and the flue box must be sealed together so that there is no possibility of leakage between them.
The correct clearances to combustible materials (i.e. false chimney breast etc.) must be adhered to. The
manufacturers’ instructions for fitting the prefabricated box must be complied with at all times.
To fit the fire using the cable fixing kit supplied, some minor adaption may be necessary for certain flue
boxes. Please ensure the firebox does not obscure the flue box outlet.
The firebox, base of the flue box, and hearth below may be drilled to allow plugs and screws to secure
installation. It is important that the sealing requirements of the appliance are met at all times and that
the flue box is sealed to any back or infill panel.
Note: The DEPTH dimension is inclusive of any back or infill panel.
In accordance with BS 5871 part 2, minimum debris collection volumes are required behind the installed
appliance.
