10) NOZZLES CHANGE
You can convert the burners for operation with
various type of gas by installing nozzles appropriate
for each gas. To perform this operation, remove
burner heads. Using spanner wrench B loosen
nozzle A (see Fig. 12) and replace it with the nozzle
that corresponds to the gas type you want to use. It
is recommended to tighten the nozzle securely.
After the above-mentioned replacement, a
technician must perform burner adjustment as
described in paragraph 9, install lead seals on
available adjustment or pre-adjustment devices,
and prepare a new factory label to replace the old
label, corresponding to the new setting of
appliance gas supply. This label is in the bag for
replaceable nozzles.
For installer’s convenience, a table is provided below
specifying burner power and heat capacity, nozzle
diameters and operating pressures for various
gases.
