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. 5).
6. For gas inlet position of appliance refer Fig 5, 6 and 7. 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 a 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 should matches or flames be used 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, perform the following:
a) Disconnect electric power before checking pressure.
b) Take off one of the gas burner cap and the relative flame
spreader in order to gain access to the burner injector.
c) Put the pressure detector directly on the burner injector.
Afterwards, 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 and light each burner. Check for a
clear blue flame without yellow tipping. If burners show any
abnormalities, check that they are situated properly and in line with
the injector nipple.
