10) REPLACING THE INJECTORS
The burners can be converted to different types of
gas by changing the injectors. To do this, first remove
the burner tops. Unscrew the injector "A" (see fig. 13).
See the table for the correct injector size. Fit the new
injector and screw it down hard.
After the injectors have been replaced, the
burner reduced rate may need to be adjusted
as explained in section 9. Reset any seals on
the regulating or pre-regulating devices.
Table lists the heat inputs of the burners, the
diameter of the injectors and the working pressures
of the various types of gas.
