a. If the reading is more than 100 milli-volts and the automatic valve still does not come on, replace the control.

b. If the closed circuit reading (“A” reading) is less than 100 millivolts, determine cause for low reading, proceed to

Section B below.

B. Thermopile Output Reading Check

(“B” Reading - Thermostat contacts OPEN - Main burner OFF)

1. Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then check pilot

voltage, 325 millivolts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
