Check the burner flames for:
1. Good adjustment
2. Stable, soft and blue
3. Not curling, floating, or lifting off.
Burner Flame
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.
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.
3.
Remove the burners.
4.
Use a bottle brush to clean burner insert and inside
of the burners.
5.
Replace burners and manifold, inspect the burner
assembly for proper seating of burners in retention
slots.
6.
Reconnect electrical power and gas supply.

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.
