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. Refer to Section 2.5.
The appliance must be used with the correct injectors for its thermal power rating
(See Table 4 in Section 1.2).
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
gas supplier 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 installer and do not start operation before the cause has been found and eliminated.
Power rating with G20
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 supply pressure is within the range 17 and 25 mbar
Non-admitted if the pressure is lower than 17 mbar or higher than 25 mbar. Inform 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.
