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

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
