b. Disconnect wires from the flame rod and ignition electrode.

d.The entire burner assembly can now be removed from the unit.
NOTE: Use all screws that were removed; they are necessary for safe and proper operation of the unit.
3Inspect and periodically clean the vent outlet (bird screen) on the access panel.
NOTE: Periodic observation of the flame and a log of C02 measurements are recommended. This will aid in determining whether the furnace is operating efficiently or if the furnace requires cleaning.
Flames should be stable, soft and blue (dust may cause or- ange tips but must not be yellow). The flames must extend directly outward from the burner without curling, floating or lifting off.
Check the burner flames for:
1.Good adjustment
2.Stable, soft and blue
3. Not curling, floating, or lifting off.
WARNING
TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK,
DO NOT REMOVE ANY INTERNAL COMPARTMENT COVERS OR ATTEMPT ANY ADJUSTMENT. CONTACT A QUALIFIED SERVICER AT ONCE IF AN ABNORMAL FLAME SHOULD DEVELOP.
At least once a year, prior to or during the heating season, make a visual check of the burner flames.
NOTE: This will involve removing and reinstalling the heat exchanger door on the unit, which is held by two screws. If you are uncertain about your ability to do this, contact a qualified servicer.
If a strong wind is blowing, it may alter the airflow pattern within the unit enough that an inspection of the burner flames is not possible.
