it on the heater. Here below are the steps
for the conversion to another combustible
gas:
►8.1.REMOVE THE VALVE AND
NOZZLE SUPPORT CONNECTION
PIPE, REMOVE THE NOZZLE
SUPPORT, REMOVE THE NOZZLE
PROCEDURE:
•8.1.1.Remove the conical tip tightening
ring on the valve side (Fig. 10).
•8.1.2.Remove the nozzle support
fastening screw (Fig. 11).
•8.1.3.Take out the nozzle support and
the gas pipe section (Fig. 12).
•8.1.4.Remove the gas nozzle (Fig. 13).
CAUTION: CAREFULLY KEEP ALL THE
COMPONENTS (GASKETS, CONICAL
TIPS, ETC.).
►8.2.CHOOSING THE NOZZLE
Choosing the right nozzle:
LPG nozzle = 5 mm diameter
G20 nozzle = 10 mm diameter
G25 nozzle = 10 mm diameter
►8.3.PLACE BACK THE VALVE AND
NOZZLE SUPPORT CONNECTION
PIPE, PLACE BACK THE NOZZLE
SUPPORT, PLACE BACK THE
NOZZLE
PROCEDURE:
•8.3.1.Attach the nozzle to the nozzle
support and ensure the connection is
airtight. Make sure the nozzle you choose
is suitable for the desired conversion (Fig.
13).
•8.3.2.Insert the nozzle support with the
pipe underneath the burner and secure it
to the base with the screw (Fig. 12-11).
•8.3.3.Tighten the conical tip tightening
fitting to the gas valve (Fig. 10).
•8.3.4.Make sure the connections are
firmly attached.
CAUTION: IF USING G20-G25 GAS,
INSTALL THE AIR REDUCTION COLLAR
(Fig. 14). THIS COLLAR IS ONLY
REQUIRED FOR G20-G25 GAS TYPES.
►8.4.ADJUST THE OUTLET
PRESSURE FROM THE GAS VALVE
CAUTION: THE ADJUSTMENT MUST
BE CONDUCTED QUICKLY AND
ACCURATELY.
After assembling the duct onto the new
nozzle, you need to set the heater's
multipurpose gas valve at the right supply
pressure. The pressure must be adjusted
when the heater is in operation and the
gas supply is connected. Before starting
the adjustment, make sure the heater is
powered on with the right type of gas for
the nozzle installed.
PROCEDURE:
•8.4.1.Identify where the gas valve
outlet pressure is taken and remove the
tightening screw (Fig. 15).
•8.4.2.Connect a flexible rubber pipe,
make sure it is firmly attached (Fig. 16).
Considering that the pressure values are
set to minimum values, use a differential
manometer or, better still, a water tube
manometer.
•8.4.3.Remove the protective cover (Fig.
17) and identify the rotation screw used to
adjust the pressure on the gas valve.
•8.4.4.Prepare the specific tool to operate
on the adjustment pin.
•8.4.5.Turn on the heater and wait for a few
seconds while the prewash is conducted.
You can then open the gas and the flame
will come on. At this exact moment you
need to rotate the pin (Fig. 18) until the
required outlet pressure value is reached
(clockwise to increase it, anticlockwise to
reduce it). After adjusting the pressure,
we recommend repeating the ignition
cycle three times with the inspection
doors closed and by checking again the
outlet pressure of the gas valve. Before
