A. Complete Millivolt System Check
(“A” Reading - Thermostat contacts CLOSED - Control
knob “ON” - Main burner should turn ON)
1. If reading is more than 175 millivolts and the au-
tomatic valve still does not come on, replace the
control.
2. If the closed circuit reading (“A” reading) is less
than 175 millivolts, determine cause for low read-
ing, proceed to Section B.
