Green in color closest to step motor
5VDC and drops to 1.0VDC (test image shown on pg 16)
Gas Pressure:
Very Important for the Function of an IPI Pilot Assembly
Inlet Pressure Test Point
Measures amount of gas coming into the valve
NG 5.0” WC to 7.0” WC
LP 11.0”WC to 13” WC
Critical to check this with all gas appliances on in house (Full Load Check)
Outlet Pressure Test Point
Measures amount of gas leaving the valve to burner orifices
Need to have EV2 energized or burner turned on to verify
Pilot Adjustment Screw:
Do not adjust as this is factory set by the valve manufacturer.
