control knob “ON,” main burner should turn ON)
a. If the reading is more than 100 millivolts 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, pro-

within minimum and maximum on data plate, then
check pilot voltage, 325 millivolts minimum. If the
minimum millivolt reading is not obtainable, replace
