Clearances to non-combustibles
Non combustible surfaces are defined as brick, metal, marble, concrete etc. and also a number of man-made materials impervious
to flame. If in doubt refer to the material manufacturer for further information before proceeding with installation.
The wall/back panel for the opening must always be non-combustible. Bare plasterboard must be protected by non-combustible
plaster or replaced with non-combustible material (e.g. Superlux board). Any gap between wall boards and the wall must be filled
using glass fibre insulation, silicone mastic or similar material to prevent heat ingress.
Any type of fire surround used with this appliance must be adequately sealed to the wall and floor to prevent excess draughts
from around the back of the fire. The temperature rating of any surround used must be 150°C minimum.
Clearances to the sides of the appliance are 100mm (4”). Clearance to the front of the appliance is 500mm (20”).
The sides and back of the appliance may be installed directly onto a non-combustible surfaces.
A non combustible shelf of any depth may be positioned above the appliance provided it is no closer than 200 mm from the top
of the appliance glass panel and the wall above the appliance is non combustible. The shelf itself and any articles placed on it must
also be tolerant of high temperatures.
Clearances to combustible materials
Combustible materials are defined as wood, fabrics, or other materials likely to combust if exposed to flame. Generally, any mate-
rial, which is likely to discolour, melt or misshape when exposed to moderate heat, should be considered as a combustible mate-
rial or surface.
Clearance to the sides of the appliance facia are 100mm (4”) but curtains, drapes and other fabrics are not permitted within a
distance of 500mm (20”) of the appliance sides. No such materials are permitted directly above the appliance regardless of dis-
tance.
The minimum clearance to the ceiling above the appliance is 800mm (31.5”) measured from the top of the appliance glass panel.
Combustible materials should not be positioned directly in front of the appliance within a distance of one metre.
A combustible shelf may be fixed to the wall above the fire, providing that it complies with the dimensions given below.
The shelf depth may be greater but the height must also be increased accordingly. An increase in height of 25 mm is required for
every 12.5 mm of additional shelf depth. For shelves that are too low protective devices can be used such as metal heat deflec-
tors, but it must be assured that the shelf does not reach an unacceptable temperature before relying on such a solution.
Under no circumstances should any electrical equipment e.g. plasma screen TV sets etc. be positioned on the wall above the appli-
ance.
Clearance to the sides and rear of the firebox are a 75mm (3“) air-gap. Clearance to the top of the firebox is a 100mm (4”) air-
gap. It should be established that any mirrors or picture frames etc. to be positioned on the wall above the appliance are able to
withstand prolonged exposure to moderate heat and moisture before proceeding with their installation.
Purpose provided ventilation of 100cm
2
is required for this appliance. An openable window or equivalent is also required. Any ven-
tilation fitted must comply with BS 5871 part 4 and BS 5440 part 2. Ventilation fitted under, or within immediate vicinity of the
appliance must not be used as it may adversely effect performance of the combustion monitoring system (ODS) system.
The appliance shall not be installed within 1 metre of any existing air vent, and any new air vent shall not be installed within 1
metre of the appliance. The requirements of other appliances operating in the space or room must be taken into consideration
when assessing ventilation requirements, this will have been carried out by your GAS SAFE registered installer. A supply of fresh
air into the room is advisable to maintain temperatures within limits.
This appliance must not be installed in a bedroom or a bathroom. For Republic of Ireland, see relevant rules in force.
The room size should be a minimum of 27m
3
(e.g. 11’ x 11’ x 8’) to allow adequate circulation of air and ensure the correct oper-
ation of the fire. This volume may include adjacent spaces but these spaces must not be separated by a door.
Note :
To calculate a
room size in cubic metres (m
3
) divide the room volume in cubic feet (ft3) by 35.3.
It should be noted that heaters create warm air currents. These currents move heat to wall surfaces next to the heater. Installing
the heater next to vinyl or cloth wall coverings or operating the heater where impurities in the air (such as tobacco smoke, can-
dle smoke etc.) exist, may cause the walls to become discoloured.
This appliance is intended as a secondary source of heat only and should not be used in a room without some form of back-
ground heating present. If the appliance is used in a room as the sole source of heat, then condensation may occur on colder sur-
faces within the room.
