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 pos-
sible.

1. Shut off electric power and gas supply to the unit.
2. Remove the screws securing the manifold to the burner
retention bracket. Remove the manifold and rotate each
burner counterclockwise to remove.

tubes. They should not be yellow. They should extend directly
outward from the burner ports without curling downward,
floating or lifting off the ports.
