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.
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.
