Safety Precautions

If you discover any of the following, shut down your
unit and contact a Lennox dealer for an inspection by a
qualified technician.
If you repeatedly hear any new or unfamiliar sounds
D
while your unit is operating, there may be a problem. For
example, poorly performing burners can produce unfa
miliar noises.
If you smell any unusual odors, your unit may be operat
D
ing improperly. For example, units can give off unfamil
iar odors if components are required to operate in ab
normal conditions.
Look for visible signs of a malfunctioning unit. Examples
D
include unusual amounts of condensate on windows in
side your house, visibly burnt components or unusual
dirt or rust accumulations on the vent pipe or in the unit.
If you experience headache, nausea, fatigue, or dizzi
D
ness, the cause could be exposure to carbon monoxide
gas. This is often misdiagnosed as the flu because
symptoms are similar. If you suffer from flu-like symp
toms that are exaggerated at home, but seem to sub
side while you are away from the house, exposure to
carbon monoxide could be the cause.
Your vigilance may pay off in early detection of a problem
before either personal injury or property damage occurs.
Do not hesitate to contact a qualified service technician as
an investment in your well being.
