Operating instructions

The location chosen for the appliance must permit the
provision of a satisfactory flue and an adequate air supply.
The location must also provide adequate space for
servicing and air circulation around the cooker.
The following notes are intended to give general
guidance:-
The initial length of flue pipe from the appliance flue
socket should be vertical for at least 600mm. Should
600mm prove impractical then a shorter length of initial
vertical flue may be used, subject to flue draught tests
proving satisfactory.
In any event, the minimum length must not be less than
3m.
The cross-sectional area of the flue serving the cooker it
must not be less than the area of the flue outlet of the
cooker. If the flue pipe is to be used it must not be less
than 100mm internal diameter.
Flue pipes and fittings should be constructed from one of
the following materials:-
a) Cement
b) Aluminium or stainless steel
c) Cast iron, mild steel, acid resistant vitreous enamel
lined
If a chimney is to be used, it preferably should be one that
is composed of or lined with a non-porous acid resistant
material. (Chimneys lined with a salt glazed earthenware
pipes are acceptable, if the pipes comply with the
regulations in force). A flue pipe constructed from one of
the materials in (a) to (c) above, should form the initial
connection to lined chimneys.
Where a chimney is to be used which is not composed of
or lined with a non-porous acid resistant material it should
be lined with a stainless steel flexible flue liner. The
internal diameter of the liner must not be less than 100mm
and the number of joints must be kept to a minimum. If the
flue liner is not connected directly to the appliance
draught diverter a flue pipe which is constructed from one
of the materials in (a) to (c) above should form the
connection between the draught diverter and flue liner.
Before connecting the appliance to or inserting a liner
into, a flue that has been previously used, the flue must
be thoroughly swept clean of any soot and loose material.
If a baffle is fitted in the flue, it must be removed before
connecting the appliance to, or inserting a liner into the
flue. The point of termination must not be within 600mm
of an openable window, air vent or any other ventilation
opening.
Installation pipes should be fitted in accordance with
current Gas Regulations. Pipework from the meter/tank to
the cooker must be of adequate size, cooker connection
size of 15mm Dia. On completion test the gas installation
for soundness and purge in accordance with the
regulations in force.
Kitchen or Internal Space Air Supply
Where the appliance is to be installed in a kitchen or
internal space, it does not require the kitchen or internal
space containing it to have a permanent air vent.
