2.5 CONVERSION TO OTHER GAS TYPES
To convert the appliance for use with another type of gas, the injectors on the main burners
and on the pilot burner need to be replaced. (See Table 5 and figure “Main burner”).
All the injectors needed for the different types of gas are contained in a bag supplied with the
appliance.
The supply pressure and the manual setting of minimum output should also be checked.
(See Table 4 – Minimum output setting).
2.5.1 REPLACEMENT OF MAIN BURNER INJECTORS
The injectors can be reached by removing the lower front panel, once the two side screws
have been unloosed.
Disconnect the tube with the injectors, undo the screws and remove.
Use a fixed wrench SW11 to remove injector and replace it with a suitable one.
Re-install the primary air regulation bracket at the distance “H” as shown in Table 5, see also
“Primary air regulation”.
