TESTING OF THE APPLIANCE
Important
Before it is put into service, the system
must be tested to check the operating con-
ditions of every single component and
identify any malfunctions. In this stage, it is
important to check that all health and safety
requirements have been complied with in
full.
To test the system, make the following checks.
1 - Turn on the gas supply tap and check that the
connections are right.
2 - Check that the mains gas is the same as that
used for commissioning of the appliance, and
carry out the conversion procedure if necessary
(see page 16).

ADJUSTING GAS VALVE SETTING
Important
This adjustment is only required if the type
of gas to be connected is different from that
used for testing after the conversion proce-
dure has been carried out (see page 16). Be-
fore making this adjustment, check that the
gas supply pressure is the same as the rat-
ed pressure for the type of gas in use (see
table at back of manual).
After testing, if necessary instruct the user in all the
skills necessary for putting the appliance into oper-
ation in conditions of safety, in accordance with le-
gal requirements.
