3.1 Adjustments

All adjustment and conversion operations must be carried out by Qualified Personnel such as
the Ferroli Technical Service.
FERROLI declines any responsibility for damage or physical injury caused by unqualified and
unauthorized persons tampering with the device.
Gas supply conversion
The unit can function with either Natural Gas or LPG
(commercial propane) and is factory-set for use with
one of the two gases, as clearly shown on the packing
and on the unit's dataplate. Whenever a different
gas to that for which the unit is preset has to be
used, a conversion kit will be required, proceeding
as follows:
1 Remove the casing.
2 Open the combustion chamber.
3 Unscrew the gas coupling A on the air/gas ven-
turi.
4 Replace the injector in the mixer with the one
contained in the conversion kit.
5 Refit the coupling A and check the connection is
gas tight.
6 Apply the sticker, contained in the conversion kit,
near the dataplate.
7 Fit the combustion chamber and casing back on.
8 Check inlet working pressure.
9 Set CO mixture as detailed (page 28).
