Checking The Supply Pressure; Safety Devices - Ariston Thermo SGA X 300 Instrucciones Para El Uso Y La Manutención

CHECKING THE SUPPLY PRESSURE

The gas supply pressure measured at
the pressure fi tting 11 (fi g.5), using a pres-
sure gauge and expressed in mbar.
ADJUSTING THE PILOT FLAME
(EUROSIT valve)
Adjust by acting on screw 11 (fi g.5).
The pilot fl ame is correctly adjusted
when its length is approximately 2-3 cm
and the fl ame touches the upper part of
the thermocouple.
Methane (G20)
Butane (G30)
LPG
Propane (G31)
