TESTING THE APPLIANCE
IMPORTANT _________________________
Before it is put into service, the system must
be tested to check the operating conditions
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 gas and water supply valves and check
that connections are tight.
2. Turn on the master switch to check the electrical
connection.
3. Check that the mains gas is the same as that
used for commissioning of the appliance, and
carry out the conversion procedure if necessary.
4. Check that the gas pressure conforms to values
stated in the table at the back of the manual.
5. Check that the combustion exhaust gases
comply with the requirements.
6. Check the water pressure and adjust if necessary.
7. Check that the safety device is operating correctly.
8. Carry out a cooking cycle without food to ensure
the appliance is operating correctly.
After testing, train the user in all skills necessary
to ensure safe operation of the appliance, in
accordance with all legal requirements.
