1.6 Gas Supply
Incoming gas service must be of sufficient size to
supply full rate without excessive pressure drop. A
gas meter is connected to the service pipe by the
Gas Supplier. Any existing meter should be checked
by the Gas Supplier to ensure that it has capacity to
pass the required rate of gas for the kettle in addition
to any other gas equipment installed.
The appliance governor is incorporated in the gas
control valve which is situated in the control cabinet.
The control valve governor is suitable for both
natural and propane gases without any conversion.
Installation pipe work should be fitted in accordance
with IEGE/UP/2. The pipe work should not be
smaller than the gas inlet connection on the kettle,
i.e. Rp ½ (½”BSPT).
An isolating cock must be located close to the
appliance to allow shut off during an emergency or
servicing. The installation must be tested for gas
soundness and purged as specified in IGE/UP.
