Gas Connection
The type of gas and the supply pressure that the equipment
was set up for at the factory is noted on the data plate and on
the packaging . This type of gas supply must be used .
The gas pipe connection is made at the right hand side of
the equipment . The size of the pipe work supplying the
appliance must not be less than the inlet connection which
is ISO 7/R 1/2” . An isolating cock is required to be close to
the appliance to allow shut down during an emergency or
routine servicing . After installation, the complete pipe work
must be checked for soundness .
Gas Supply
The local gas region should be consulted at the installation
planning stage in order to establish the availability of an
adequate supply of gas and to ensure that the meter is
adequate for the required flow rate . The pipe work from
the meter to the appliances must be of an appropriate size .
Where a number of appliances are installed in a battery, no
more than five should be served by any one supply pipe .
INSTALLATION Continued
All fixed ( non mobile ) appliances MUST be fitted with a
manual gas cock upstream of the appliance to provide a
means of isolation for servicing or cleaning purposes . A
union or similar means of disconnection must be provided
between the gas cock and the appliance .
A manually operable valve must be fitted to the gas supply
to the kitchen to enable it to be isolated in an emergency .
Wherever practical, this shall be located either outside the
kitchen or near to an exit in a readily accessible position .
Where it is not practical to do this, an automatic isolation
valve system shall be fitted which can be operated from a
readily accessible position near to the exit .
At locations where the manual isolation valve is fitted or
the automatic system can be reset a notice MUST be fitted
stating:
“All downstream burner and pilot valves must be turned
off prior to attempting to restore the supply. After
extended shut off, purge before restoring gas.”
COMMISSIONING
The whole of the gas installation, including the meter,
should be inspected, purged and tested for soundness in
accordance with the codes of the Country of destination .
1 . Ensure that all controls are in the “ ” position and turn
on the main gas supply and electrical mains .
2 . Remove the drip tray and roll out rack assembly and
connect a U-gauge manometer to the pressure test
point on the main manifold . Operate the main burners in
accordance with the instructions given in the Operation
section .
3 . Check that the setting pressure is correct per TABLE D . If
necessary, adjust the supply pressure to give the required
setting .
Burner Adjustments
Minimum Flame Setting
1 . Set the gas tap to the low “ ” position .
2 . Connect a U-gauge manometer to the pressure test
nipple located downstream of the gas tap .
3 . With a flat screwdriver, turn the adjuster on the tap body
clockwise to reduce pressure or counter-clockwise to
increase pressure . Set the pressure to correspond with
TABLE E .
