MAIN BURNER FLAME (QUALIFIED SERVICER ONLY)
Flames should be stable, soft and blue (dust may cause orange 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.
Burner Flame
For further information on the yearly inspection, consult the User Manual. It is recommended that a qualified servicer inspect and service the unit at least once each year.
Turn the unit on at the thermostat. Wait a few minutes, since any dislodged dust will alter the normal flame appearance. Flames should be predominantly blue and directed into the tubes. They should not be yellow. They should extend directly outward from the burner ports without curling downward, floating or lifting off the ports.
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.
CLEANING BURNERS
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.
