5. CONNECTIONS

• Any installation work or maintenance to the sup-
ply system (gas, electricity, water) must only be
carried out by the utility company or an authorised
installation technician.
• Refer to the appliance dataplate for the product code.
• See the installation diagram for the type and position of
appliance connections.
5.1. GAS APPLIANCES
IMPORTANT! This appliance is arranged and tested to opera-
te with G20 gas 20mbar; to convert it to another type of gas,
follow the instructions in par. 5.1.6. of this section
5.1.1. BEFORE CONNECTING
• Make sure the appliance is arranged for the type of gas to
be used. Otherwise, carefully follow the instructions given
in the section: "Gas appliance conversion / adjustment".
• Fit a rapid gas shutoff cock/valve ahead of each appliance.
Install the cock/valve in an easily accessed place.
• Clean the pipes to remove any dust, dirt or foreign matter
which could block the supply.
• The gas supply line must ensure the gas flow necessary
for full operation of all the appliances connected to the
system. A supply line with insufficient flow will affect cor-
rect operation of the appliances connected to it.
Attention! Incorrect levelling of the appliance can affect
•
combustion and cause malfunctioning.
5.1.2. CONNECTION
• See the installation diagram for the position of the gas
connection on the bottom of the appliance.
• Remove the plastic protection (if present) from the gas
union before connecting.
• After installation, use soapy water to check connections
for leaks.
• The gas connection is male 1/2" BSP
5.1.3. SUPPLY PRESSURE CHECK (all versions)
Make sure the appliance is suitable for the type of gas availa-
ble, according to that given on the dataplate (otherwise, follow
the instructions given in the section "Conversion to another
type of gas"). The supply pressure must be measured with the
appliance operating, using a pressure gauge (min. 0.1 mbar).
• Remove the control panel.
• Remove screw "N" from the pressure point and connect
the pressure gauge "O" (fig. 2A-2B).
• Compare the value read on the pressure gauge with that
given in Table B (see handbook Appendix)
• If the pressure gauge gives a reading outside the range of
values in Table B, do not switch the appliance on. Consult
the gas company.
5.1.4 GAS PRESSURE REGULATOR
If the gas pressure is higher than that specified or is difficult
to regulate (not stable), install a gas pressure regulator (ac-
cessory code 927225) in an easily accessed position ahead
of the appliance.
The pressure regulator should preferably be fitted horizontally,
to ensure the right outlet pressure:
• "1" connection side gas from mains.
• "2" pressure regulator;
• "3" connection side gas towards the appliance;
The arrow on the regulator (
flow direction.

NOTE! These models are designed and certified for use
with natural or propane gas. For natural gas, the pres-
sure regulator on the header is set to 8" w.c. (20mbar).
AUSTRALIA: the gas pressure regulator supplied with the
appliance must be fitted to the appliance inlet. Adjust the
test point pressure with one burner operating at maximum
setting as follow:
- 1.0 KPa for Natural gas
- 2.65 KPa for Propane gas
5.1.5. PRIMARY AIR CHECK
The primary air is correctly adjusted when the flame does
not "float" with the burner cold and there is no flareback with
the burner hot.
• Undo screw "A" and position aerator "E" at distance "H" given
in Table B; retighten screw "A" and seal with paint (fig. 3A).
5.1.6. CONVERSION TO ANOTHER TYPE OF GAS
Table B "Technical data/gas nozzles" gives the type of nozzles
to be used when replacing those installed by the manufacturer
(the number is stamped on the nozzle body). At the end of the
procedure, carry out the following check-list:
Check
• burner nozzle/s replacement
• correct adjustment of primary air supply to
burner/s
• pilot nozzle/s replacement
• minimum flame screw/s replacement
• correct adjustment pilot/s if necessary
• correct adjustment of supply pressure
(see technical data/gas nozzles table)
• apply sticker (supplied) with data of new gas type
used
) indicates the gas
