The machine is set up for being supplied with methane gas (G20),
this means that the gas injector (O) and the gas regulator (N) are
calibrated for methane gas.
For operation with GPL gas (liquid gas G30) or town gas, the gas
injector (O) must be replaced with the injector enclosed with the
machine (see gas injector table).
To light the gas burner keep the gas n-oiff valve button (4) pressed
down in order to allow the gas to flow to the burner, then operate
the piezoelectric ignition push-button (5).
NB: The on-off valve button must remain pressed down for
a few seconds to allow the thermo-couple to operate.
Adjust the air flow by means of the air adjustment ring nut (P) turning
clockwise to reduce the flow and anti-clockwise to increase it, so
as to obtain a blue flame (avoid long or excessively oxidising flames
to avoid damaging the boiler).
Wait for the boiler to reach an operating pressure of 1.1÷ 1.3 atm
and for the flame to be reduced to a minimum. If the gas regulator
(N) requires calibration, proceed as follows : turn the minimum
adjustment screw (Q) clockwise to reduce the flame and anti-
clockwise to increase it.
To increase or reduce maximum pressure in the boiler, turn the
pressure adjustment screw ® clockwise to decrease the pressure
and anti-clockwise to increase it.
