Measuring Thermopile

Taking a Millivolt Reading

1. Make sure the multimeter is set to mV.

2.Touch the thermopile leads with the multimeter probes as shown.

Adjusting the Thermopile

1.Compare the multimeter reading to the Thermopile mV table.

Thermopile mV Table

Pilot lit	Pilot lit with burners on
PP1 to PP2	PP2 to TH2 approximately
600± mV	300 mV less than pilot alone

2.Insert a flathead screwdriver into the Pilot Adj. cap and turn counter-clockwise to remove it.

mV Gas Valve Resistance Readings Table

Pilot Valve	Main Valve
TH 1 to PP 2 10.4 Ω	TH 2 to PP 2 2.0 Ω

3.Insert flathead screwdriver into Pilot Adj. screw and turn counter-clockwise to increase the mV pressure or clockwise to decrease the mV pressure.

4. Disconnect the multimeter.
