("A" READING - CONTACTS CLOSED - CONTROL KNOB "ON" - MAIN BURNER SHOULD BE COME 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 — proceed as follows:
