2.8
The minimum height from the extreme top surface of the fire to the underside
of a shelf or other projection made of wood or any other combustible material is
shown in graph 1.
2.9
There is no restriction on the depth of non-combustible projections but a space
of at least 30mm should be allowed above the top of the appliance to enable removal
of the case front.
2.10
It is advisable that combustible fabrics such as curtains are not fitted above the
fire. If, however, this is unavoidable, a clearance of at least 150mm must be
maintained from the extreme bottom edge of the fabric to the extreme top surface of
the fire.
2.11
The appliance can be installed with or without a non-combustible hearth. If a
non-combustible hearth is installed, there must be a minimum clearance from the
top surface of the hearth to the absolute bottom of the appliance of 18mm (see figure
1). The hearth must be at least 700mm wide x 300mm deep. The non-combustible
hearth material must be at least 12mm thick. Its top surface should be preferably
50mm above floor level to discourage the placing of carpets or rugs over it.
If the appliance is not installed with a hearth meeting the above conditions, the
minimum distance from the top surface of the finished floor covering (including any
carpet etc.) to the absolute bottom of the appliance must be at least 40mm (see
figure 1).
2.12
A hole 152mm (6in) is required through the wall for the flue unit.
