Bubble CORNER - Distances from Combustible Materials

11
combustible materials.
Details of minimum hearth sizes are set out in FIG1.
The fireplace must allow a good circulation of air around the appliance to ensure that
maximum heat is transferred into the room and also to prevent the fireplace from
overheating.
A gap of at least 6” either side, 18” above and 3” behind the appliance should allow
sufficient air circulation but be aware that the Building Regs may well call for greater
distances.
If a wooden mantelpiece or beam is used in the fireplace construction, it should be a
minimum of 18 inches and preferably 24 inches from the appliance in both vertical and
horizontal directions.
In some situations it may be necessary to shield the mantelpiece or beam with a suitable
fireproof material.

Dimensions shown in Table 2 are the minimum safe distances which combustible materials
should be kept away from the wood or oven stove.
Note that on some appliances the rear clearance is reduced because of the rear heat
shield or the rear face of the boiler, in both cases the radiated temperature is reduced.
