Reading the inlet pressure
The inlet pressure can be read at the pressure test point E with or without both automatic shut-off valves
energized.
Pilot burner ignition
When the automatic shut-off valve EV1 is powered, it permits the gas to supply the pilot burner outlet
(applications with intermittent pilot) after passing through the inlet filter, the pilot filter and the pilot
flow rate restrictor.
Main burner ignition
When both automatic valves, EV1 and EV2, are energized, gas passage to the main burner is opened.
Outlet pressure
The outlet pressure is read at the test point A.
