Installation, Operation & Maintenance Manual
15.5 Ignitor (Qualifi ed Service Technicians Only)
If the ignitor and the surrounding air are at about 70°F and the
ignitor wires are not connected to any other electrical components.
the resistance of the ignitor should not exceed 200 ohms. If it
does? the ignitor should be replaced

15.6 Burners

WARNING: FIRE, EXPLOSION, ELECTRICAL SHOCK OR
CARBON MONOXIDE POISONING HAZARD
 To avoid personal injury or death. Do not remove
any internal compartment covers or attempt any
adjustment. Electrical components are contained in both
compartments. Contact a qualifi ed service agent at once if
an abnormal fl ame appearance should develop.
Periodically during the heating season perform a visual check of the burner fl ames.
Turn the furnace on at the thermostat. Wait a few minutes since any dislodged
dust will alter the normal fl ame appearance. Flames should be stable quiet soft
and blue with slightly orange tips. They should not be yellow. They should extend
directly outward from the burner ports without curling downward fl oating or lifting
off the ports. See Figure 40 (page 48). Contact a qualifi ed service agent at once
if an abnormal fl ame appearance should develop or the burners have a heavy
accumulation of soot and carbon.
WARNING:
Only a qualified contractor, installer or service agency can

clean the burners.
15.7 Inspecting the Heat Exchanger (Qualifi ed Service Technicians Only)
NOTICE:
If the heat exchangers get a heavy accumulation of soot

and carbon, they must be replaced rather than cleaning
them. A heavy build-up of soot and carbon indicates that
a problem exists which needs to be corrected, such as
improper adjustment of manifold pressure, insuffi cient
or poor quality combustion air, incorrect size or damaged
manifold orifi ce(s), improper gas, or a restricted heat
exchanger. In these scenarios, the heat exchanger must be
replaced
Inspect the heat exchanger for excessive rust, cracks, or holes. Visual inspection
is always best, but requires training and practice. There are tools (fi eld supplied)
available to assist, such as inspection cameras and dye penetration inspection
systems. Inspect the metal fl ue for rust or holes, and make sure it's supported
properly.
