27. SERVICE AGENCY PROCEDURES
MAIN BURNER
Observe the main burners in operation. The flame
should be mostly “blue” with possibly a little orange
(not yellow) at the tips of the flame. The flames
should be in the center of the heat exchanger tubes and
not impinging on the heat exchanger surfaces
themselves.
Observe the fire until the blower starts (there is a
normal delay period until the heat exchanger warms
up). There should be no change in the size or shape of
the flame. If there is any wavering or blowing of the
flame on blower start-up, it is an indication of a
possible leak in the heat exchanger.
28. MAINTAINING UNIT IN GOOD
WORKING ORDER
The unit should be inspected annually by a qualified
service agency.
BURNERS / HEAT EXCHANGER / FLUE GAS
PASSAGE WAYS
The burners, heat exchanger and interior flue gas
passages may be inspected using a light on small
mirror or an extension handle. Remove the screws
securing the inducer and collector box. Now inspect
the upper tubes of the heat exchanger.
Check the exterior of the heat exchanger and the
interior flue gas passages for any evidence of
deterioration due to corrosion, cracking or other
causes. If signs of sooting exist, remove the burners
and clean the heat exchanger, as required.
