A. Complete Millivolt System Check
(“A” Reading - Thermostat contacts CLOSED - Control knob “ON” - Main burner should turn ON)
1. If the reading is more than 175 Millivolts and the automatic valve still does not come on, replace the
control.
. If the closed circuit reading (“A” reading) is less than 175 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, 500 Millivolts minimum. If the minimum Millivolt reading is not obtainable, replace
pilot.
