Millivolt Gas Valves

Part # 023625 (natural) & 023624 (LP)

MILLIVOLT CONTROL VALVE

To check Resistance of the gas valve, connect one
wire to the valve as shown.
1. Resistance between the THTP & TH terminals
must be 11.5⍀±0.2⍀
2. Resistance between the THTP & TP terminals
must be 10.0⍀±0.2⍀
If resistance is outside of specifications listed, the gas
valve must be replaced.
Before replacing thermopile check millivolt
readings.
THERMOPILE READINGS:
With all wires connected, with the pilot on and burners
off, the thermopile reading at the TP&THTP terminals
should be ~500mv. With the burners on, the millvolt
reading should be ~200mv. Areplacement thermopile
part # is 022770.
