4.4 CONVERSION
TO ANOTHER GAS
For the functioning with butane (G30) or
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. 27):
– Close the gas cock.
– Undo the burner group
– Replace the main nozzles (5) supplied in
kit, and placing the copper washer (4); 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 (11 fig. 21).
– For the setting of the values of the maxi-
mum gas pressure and the minimum fol-
low the indications as specified in point
4.2.
Once the operating pressure chan-
ges have been carried out seal the
regulators.
– The supply pressure must 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 capa-
city of all the gas connections must be
tested, using soapy water and special
products, and avoiding the use of naked
flames. The conversion must be carried
out only by authorised personnel.
4.5 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.
4.6 REMOVAL OF
OUTER CASING
For easy maintenance of the boiler it is pos-
sible to completely dismantle the casing fol-
lowing these simple instructions (fig. 28):
– Pull the front panel (5) fixed with pin clut-
ches forward.
– Unscrew the two screws that fix the con-
trol panel to the casing.
– Remove the side panel (6) by unscrewing
the two screws that fix it to the upper
bracket (7) and to the support of the
control panel. Push upwards to free it
from the notches in the right side.
– Unscrew the four lower screws that fix
the sides to the support of the control
panel and the two screws that fix it to
