Cooker Flue Connection
The position of available type of flue layouts are shown
in Figs. 2, 3 and 4, the cooker flue chamber is adaptable
to provide either top or back flue outlets, by means of the
reversible loose socket.
(a)
Rear Flue Outlet
This must only be used where there is a brick flue
immediately behind the cooker. Provision must be
made for a condensate collecting vessel and cleaning
door. See Fig. 3.
NOTE: EXTENDED HORIZONTAL FLUE PIPE
CONNECTION IS ALLOWED UP TO A MAXIMUM OF
150mm IN LENGTH. NO BEND CONNECTIONS ARE
ALLOWED. WHEN BURNING BITUMINOUS COAL,
BACK OUTLETS SHOULD NOT BE USED.
(b)
Top Flue Outlet
The cooker should be connected to the main flue via
a 125mm minimum diameter cast iron pipe or
appropriately internally/externally vitreous enamelled
mild steel pipe and be sealed to the cooker flue
chamber with soft rope and fire cement.
Any bends in the flue pipe must not be less than 135°
(45° from horizontal) and be complete with a cleaning
door.
Flue Layouts
In Fig. 2 the cooker is installed in an existing recess.
There must be a clearance of not less than 150mm
between the top of the flue pipe and any overhanging
brickwork.
Any cavities or pockets above the register plate should
as far as possible be filled and if necessary the flue pipe
should be extended into the throat of the chimney and
soot door provided for chimney sweeping.
If a flue liner or insulated chimney is used, the size
should not be less than 150mm.
In Fig. 3 the cooker is connected direct to a brick flue.
Horizontal pipe runs between cooker and brick flue must
not be used.
In Fig. 4 the cooker is connected to an existing brick flue
with a length of flue pipe. Square bends and horizontal
runs must not be used. There must be a cleaning door at
every bend.
NOTE: WHATEVER METHOD OF INSTALLATION IS
EMPLOYED, AIR MUST NOT BE ALLOWED TO
ENTER THE CHIMNEY EXCEPT THROUGH THE
COOKER. ALL JOINTS MUST BE AIRTIGHT.
