The appliances should not be fitted closer than shown in the chart, from combustible
materials, e.g. a wooden fire surround or stud wall.
When fitted against a wall made of combustible material e.g. a wooden stud wall with
plasterboard, if the distance is less than the safe distance specified, extra non-combustible
material of 75mm (min.) should be fitted behind the stove.
When fitted inside a masonry or
similar non-flammable material recess, e.g., fireplace opening, there is no minimum
distance; the gaps are only an aesthetic consideration.
Hearths
The cooker should stand on a non-combustible heath of minimum thickness 12mm (1/2”).
This should extend a minimum 225mm (9”) in front of the cooker. When the cooker is free-
standing, the hearth should also extend a minimum of 150mm (6”) either side of the cooker.
The hearth must be capable of taking the load of the appliance. Suitable measures, (e.g. a
load distribution plate) should be taken if not, to ensure stability.
The hearth should be flat and at the same height or slightly higher than the main floor. If tiles
are added in front of the cooker afterwards, it is impossible to remove the cooker for any
major maintenance. We recommend tiling the floor first before installation.
Air supply
All hydrocarbon burning appliances require an oxygen/air supply.
If the chimney/cooker is to be fitted on an external wall the air supply can be taken straight
from the outside. A 4” (100mm) diameter hole needs to be drilled in the correct place,
138mm above the hearth and the cooker ‘manifold/extension air pipe’ kit purchased and
fitted. A proprietary grille is supplied with the kit, if not used an air brick or non

closing vent
should be fitted to ensure the air supply is not blocked in any way.
The manifold method of supplying air is always to be preferred as there will be no draught in
the room especially when the cooker is not in use.
If the cooker is not on an outside wall or the direct air supply method cannot be used, an air
vent must be supplied in the room in which the cooker is fitted.
The sizes of the vent required is: 1650mm sq. (50mm diam.)
Only permanently open vents can be used and consideration should be given to draught
when the cooker is not in use. Site these vents carefully. The vent covers should comply with
Building Regulations Part J and should be sited where they cannot be blocked.
Extractor Fans: These suck air out of the room and cause a negative pressure in the room so
they must have their own air vent to counter this. Even when the air is taken directly from
