adequate air supply for correct combustion and
operation.
b) Adequate space for maintenance and air
circulation.
c) Solid floor or base of non-combustible material
which is capable of supporting the total weight.
PRE-INSTALLATION CHECK
Before installing your new Cooker, check that the
chimney is clean and clear of obstructions.
Cracked brickwork and leaking joints should be
made good and tested accordingly. The chimney
should have a cross sectional area of at least
176sq.cm (28.28 in) or an inner diameter of 15 to
23cm (6 to 9in).
Do not connect to a chimney serving another appli-
ance. Always ensure that the connection is to a
chimney of the same size - never connect to one of
smaller dimensions. Chimneys wholly constructed
of single skin pipe are not recommended under any
circumstances. Due to their inability to retain heat
such chimneys will inevitably give rise to smoking,
down draught and the formation of condensation.
CLEARANCES TO COMBUSTIBLES
The cooker should not be installed at zero clear-
ance to combustible materials. The sides should
have a minimum clearance of at least 7.5cm
(3inches) from combustible materials unless other-
wise fully insulated.
When the cooker is backed up against a wall of
combustible material it should have adequate
protection in the form of non-asbestos millboard
covered with sheet steel.
CHIMNEY HEIGHT
The flue must be high enough (more than 4.6m in
any case) to allow the flue gases to vent into
clear air, away from the turbulence that may be
caused by roof structures, other chimney
stacks etc. The venting position should be in
accordance with the Building Regulations.
FLUE PIPES
Where the standard masonry chimney is not
available, a proprietary type of non-com-
bustible and noncorrosive 6” (150mm) twin
wall, fully insulated pipe may be used. The pipe
must terminate at a point not lower than the
main ridge or adjacent outside obstructions.
With such installations access to the chimney
must be provided for cleaning purposes.

The installation must comply with the following:
The Building Regulations : Part J England & Wales,
Part F Section III Scotland, Part L Northern Ireland.
