the heat output see the pressure/heat out-
put diagrams for natural gas (methane)
and butane or propane gas are available
(fig. 22 - 22/a).
5.4 CONVERSION
TO ANOTHER GAS
For the functioning with propane (G31) gas,
a kit with that needed for the conversion is
supplied.
To convert from one gas to another carry
out the following operations (fig. 23):
– Close the gas cock.
– Undo the burner group
– Replace the main nozzles (4) supplied in
kit, and placing the copper washer (3); to
carry out this operation use a ø 7 wrench.
– Insert the bridge of the “GPL-MET” con-
nector of the electronic panel onto the
“GPL” position (7 fig. 17).
– For the setting of the values of the maxi-
mum gas pressure and the minimum
follow the indications as specified in
point 5.2.
Once the operating pressure changes
have been carried out seal the regula-
tors.
– The supply pressure mus t never be
greater than 50 mbar.
– Once the operations have been finished
cover, with the label supplied, the gas
pre-setting data on the data tag.
NOTE: After assembly the sealing capaci-
ty of all the gas connections must be test-
ed, using special products, and avoiding
the use of naked flames. The conversion
must be carried out only by authorised
personnel.
5.5 DISASSEMBLY
OF EXPANSION VESSEL
For disassemble the expansion vessel pro-
ceed in the following way:
– Make sure that the boiler has been emp-
tied of water
– Unscrew the union that connects the
expansion vessel and the screw that
release it from its bracket.
Before beginning to fill the system, make
sure that the expansion vessel is pre-filled
to a pressure of 0.8 ÷ 1 bar.
5.6 CLEANING AND MAINTENANCE
Carry out the cleaning of the generator in
the following way:
– Remove the electricity supply to the boil-
er and close the gas supply cock.
– Dismantle the burner - gas manifold
group (fig. 23).
– To clean direct a stream of air towards
the inner part of the burner to blow out
any dust that has accumulated.
– Then clean the heat exchanger removing
dust and combustion deposits.
– In cleaning the heat exchanger and that
of the burner, chemical products or steel
brushes must never be used.
– Make sure that the top perforated part
of the burners is free of encrustations.
– During the assembly and disassembly of
t he bur ner it is r ecommended t hat
attention be paid to the ignition and
detection electrodes.
– Reassemble the parts removed from the
boiler, observing the succession of the
phases.
– Check the functioning of the main burner.
– After the assembly all the gas connec-
tions must be checked for the seal, using
soapy water or specific products, avoid-
ing the use of naked flames.
The programmed maintenance of the gen-
erator is carried out annually.
