INSTALLATION

Fig.8a
LOCATION
When choosing a location for this appliance you
must have:
(a)
Sufficient room for the installation (see
clearances), a satisfactory flue, and an
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 176
sq. cm (28.28 ins) or an inner diameter of 15 to
23cm (6 to 9 ins). A similar direct air inlet is
required in the room to support combustion.
CHIMNEY/FLUES
The chimney should have a cross sectional area of
at least 176 sq. cm (28 sq. ins) or an inner diameter
of 150mm to 230mm. (6” to 10”). (See fig. 8 & 8a).
Do not connect to a chimney serving another
appliance. 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 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.
The flue must be high enough (more than 4.6m
(15ft.) in any case) to allow the flue gasses 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 1.0m (3’3”)
above any obstruction within a 7.6m (24’9”) radius,
if down draughts are to be avoided.
COOKER CLEARANCE
The Cooker should not be installed at zero
clearance to combustible materials. The sides
should have a minimum clearance of at least 7.5
cm (3”) from combustible materials unless
otherwise fully insulated.
FLUE PIPES
Where the standard masonry chimney is not
available, a proprietary type of non-combustible or
non-corrosive material 125mm (5”) 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.
Horizontal runs more than 150mm (6”) and 90
o
bends numbering more than 2 per installation
should be avoided.
Flues should be vertical wherever possible and
where a bend is necessary, it should not make an
angle of more than 37.5
o
with the vertical.
IMPORTANT: ALL FLUE CONNECTIONS MUST
BE
THOROUGHLY
SEALED:
BLOCKED
CHIMNEY’S ARE DANGEROUS, USE ONLY
RECOMMENDED FUELS, KEEP CHIMNEYS
AND FLUEWAYS CLEAR.
