Safety Precautions
If you discover any of the following, shut down your unit,
and contact a dealer for an inspection by a licensed
professional service technician (or equivalent).
• If you repeatedly hear any new or unfamiliar sounds
while your unit is operating, there may be a problem.
For example, poorly performing burners can produce
unfamiliar noises.
• If you smell any unusual odors, your unit may be
operating improperly. For example, units can give off
unfamiliar odors if components are required to operate
in abnormal conditions.
• Look for visible signs of a malfunctioning unit.
Examples include unusual amounts of condensate on
windows inside 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
dizziness, the cause could be exposure to carbon
monoxide gas. This is often misdiagnosed as the
u because symptoms are similar. If you suffer from
u-like symptoms that are exaggerated at home, but
seem to subside 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 qualied service technician as
an investment in your well being.
Planned Service
You should expect a service technician to check the
following items during an annual inspection. Power to the
unit must be shut off for the service technician’s safety.
Fresh air grilles and louvers (on the unit and in the
room where the furnace is installed) – Must be open and
unobstructed to provide combustion air.
Burners - Must be inspected for rust, dirt, or signs of water.
Vent Pipe - Must be inspected for signs of water, damaged
or sagging pipe, or disconnected joints.
Unit Appearance - Must be inspected for rust, dirt, signs if
water, burnt or damaged wires, or components.
Blower Access Door - Must be properly in place and
provide a seal between the return air and the room where
the furnace is installed.
Return Air Duct - Must be properly attached and provide
an air seal to the unit.
Operating Performance - Unit must be observed during
operation to monitor proper performance of the unit and
the vent system.
Combustion Gases - Flue products must be analyzed
and compared to the unit specications.
Problems detected during the inspection may make it
necessary to temporarily shut down the furnace until the
items can be repaired or replaced.
Pay attention to your furnace. Situations can arise between
annual furnace inspections that may result in unsafe
operation. For instance, items innocently stored next to
the furnace may obstruct the combustion air supply. This
could cause incomplete combustion and the production of
carbon monoxide gas.
