ed on the data plate in order to prevent
serious damage to the heater.
The gas regulator must be installed out-
side the building that needs to be heated
and must guarantee a supply at a pres-
sure in line with national regulations and
the heater's technical specifications. The
regulator can be installed indoors only in
a suitably ventilated area. National regu-
lations will help you identify the correct in-
stallation.
Connect the heater to the gas mains by
placing the utmost attention on the kind of
connection (ISO 7-1:1994 thread suitable
for sealing on a conical thread). The gas
pipes must have a suitable size, position
and anchoring. During the first start-up,
use an approved device to check for any
leaks due to incorrect tightening or dam-
age to the gas supply circuit.
►►7. CONNECTION TO THE
ELECTRICITY MAINS
READ THE WARNINGS CAREFULLY
AND FOLLOW THE RECOMMENDA-
TIONS CONTAINED IN THIS INSTRUC-
TION MANUAL BEFORE AND DURING
INSTALLATION.
THE POWER SUPPLY LINE AND CON-
NECTION MUST BE CARRIED OUT
BY AN QUALIFIED TECHNICIAN BY
USING SUITABLE DEVICES AND IN-
STRUMENTS, IN ACCORDANCE WITH
NATIONAL REGULATIONS AND CUR-
RENT STANDARDS.
••IMPORTANT: The heater must be con-
nected to a suitable differential and mag-
netothermal control system that ensures
the power supply is disconnected in the
event of any anomalies of the heater. For
the correct functioning of the heater, it is
necessary to verify its perfect connection
of the grounding.
We recommend using a 1,5 mm² (AWG
16) H07 type cable with length not exceed-
ing 5 m. After making sure the heater is
disconnected from the gas mains, open
the electrical panel (Fig. 7), insert the sup-
ply cable in the cable gland (Fig. 8) and
connect the cables to the suitable terminal
board (Fig. 9). Upon completing connec-
tion restore the electrical panel.
►►8.CONVERSION TO ANOTHER
TYPE OF GAS
READ THE WARNINGS CAREFULLY
AND FOLLOW THE RECOMMENDA-
TIONS CONTAINED IN THIS INSTRUC-
TION MANUAL BEFORE AND DURING
INSTALLATION.
THE CONVERSION TO ANOTHER TYPE
OF GAS MUST BE CARRIED OUT BY
AN AUTHORISED TECHNICIAN OR BY
THE AUTHORISED TECHNICAL SUP-
PORT CENTRE BY USING SUITABLE
DEVICES AND INSTRUMENTS, IN AC-
CORDANCE WITH NATIONAL REGULA-
TIONS AND CURRENT STANDARDS.
••IMPORTANT: The conversion must be
carried out after closing and disconnecting
the heater from the gas and electricity
mains (Fig. 24).
The types of gas compatible with this
kind of heater are briefly reported in the
gas type label. The gas setting, before
the conversion of the heater, can be
identified based on the data plate applied
on the heater. When the gas conversion
has been completed, permanently report
the parameters of the new setting on the
neutral data plate supplied and then apply
