microns on the nozzle.

For changing the nozzles:

1. Remove the pan support;

2. Remove the burners;

3. Using a socket spanner 7 unscrew the

nozzles (fig. 15) and replace them with

those required for the type of gas in use

(see table no. 2).

Put in place the burners and the pan

supports.

burners.

go out.
