4. For LPG models the gas supply is connected to the regulator which is supplied loose. The inlet connection
has a 1/2” B.S.P. male thread. IT IS ESSENTIAL THAT THE ELBOW ON THE APPLIANCE BE HELD
FIRMLY WITH A SPANNER WHEN CONNECTING THE SUPPLY. DO NOT OVER TIGHTEN. The
regulated pressure For LPG is 11” w.c. (See Fig. 5A).
5. For NG models the gas supply is connected to the regulator which is supplied loose. The inlet connection
has a 1/2” B.S.P. male thread. IT IS ESSENTIAL THAT THE ELBOW ON THE APPLIANCE BE HELD
FIRMLY WITH A SPANNER WHEN CONNECTING THE SUPPLY. DO NOT OVER TIGHTEN. The
regulated pressure For NG is 4” w.c. (See Fig. 5A).
6. For gas inlet position of appliance refer Fig 5A and 5B. After installing the gas supply and making all
connections check thoroughly for possible leaks. Turn all control knobs on the unit to ‘OFF’ position. Open
the valve on the gas supply. Using a soap and water solution check each gas connection one at the time, by
brushing the solution over the connection. Presence of bubbles will indicate a leak. Tighten the fitting and re-
check for leaks. If it is not possible to correct the leak, replace fitting. Under no circumstances use matches
or flame for checking leaks.
It is essential that the gasket and the pressure test point stopper are properly installed to avoid gas leakage

7.To checking inlet pressure at the appliance operate as follow:
a) Disconnect electric power before pressure checking be carried out.
b) Take off one of the gas burner cap and the relative flame spreader in order to get access to the
burner injector.
c) Put in position the pressure detector directly on the burner injector afterward open the relative burner
knob at maximum position keeping it pressed, then measure the outlet pressure from the burner
injector.
d) Once the pressure checking has been carried out, replace the burner cap and flame spreader in the
correct and original position and re-connect electric power to the appliance.
8. Turn on appliance control cock and light each burner. Check for a clear blue flame without yellow tipping.
If burners show any abnormalities check that they are located properly and in line with the injector nipple.
