2.3. CHECKING THE OPERATION OF THE GAS SYSTEM

 Check that the appliance has been prepared (category and type of gas) equivalent to
the family of gas available on site. If not, it is necessary to convert the appliance to
whatever is available. See the paragraph "Conversion to other types of gas".
 The appliance must be used with the correct injectors for its thermal power rating (See
table 4 in the "Technical data").
 The operation of the appliance with its heating capacity depends on the inlet pressure
and the calorific power of the gas.
 The pressure range (inlet pressure) within which the appliance is allowed to operated is
stated of the paragraph "Technical Data". The appliance shall not be operated out of
the given pressure range. If pressure should differ from the figures stated in table 6b,
advise the gas board or the company which has installed the system.
Power rating with G30
The power rating is achieved by using the
injectors indicated in the table without any
preliminary regulation.
The possibility of operation depends on
the supply pressure available:
admitted if inlet pressure is within
the range 20-35 and 25-45 mbar.
non admitted if the pressure is
lower than 20-25 mbar or higher than
35-45 mbar. Inform the installer and do
not start operation before the cause has
been found and eliminated.
- The power rating for the maximum position is obtained in all the burners when the right
injectors have been installed. Compare the injectors installed with those indicated in
table 4.
- There is no the minimum power because the main burners work in ON/OFF.
- Request the heat value to the gas supply board and control the injectors according to
the data indicated in table 4.
