Replacing Nozzles
The burners can be adapted to suit different
types of gas by fitting the nozzles that corres-
pond to the gas used. To do this, it is
necessary to remove the burner heads and
use a straight key "B", to unscrew the nozzle
"A" (see Fig. 7) and replace it with a nozzle
corresponding to the gas used.

"A" (see Fig. 7) and replace it with a nozzle
corresponding to the gas used.
Be sure the nozzle is seated tightly.
After making these replacements, the technician must regulate the burners
as described in Adjustments on the previous page and apply the label
corresponding to the new gas type in place of that previously applied. This
label is contained in the spare nozzle bag.

For ease of the fitter, we have prepared a table indicating the flow capacities, the
heat capacities of the burners, the diameter of the nozzles and the working
pressure for the various types of gas.
