until it stops. Depress knob and turn clockwise 
to OFF. Turn knob on White Rodgers 180° either way to off. Do not force.
5− Replace heat section access panel.
WARNING
Danger of explosion. Can cause injury or death. Do not attempt to light manually. Unit has a direct spark ignition system.
Flue Passage and Vent Inspection
Annually, before heating season, inspect combustion air louvers, vent cap, heat exchanger, burners and combus tion air inducer for corrosion, deterioration or deposits of debris. Remove any obstructions or blockage.
Burner Flame
WARNING
Danger of explosion and fire. Can cause injury or product or property damage. Periodically inspect burner flame to en sure proper unit operation.
The primary air is permanently set for normal operation. The flame will be basically blue with some clear yellow streaking in the end of the flame. Inspect burner flame pe riodically during heating season using inspection port provided on the burner access panel.
