Safety Precautions

Planned Service

If you discover any of the following, shut down your unit, and contact an independent Lennox dealer for an inspection by a qualified technician.

S 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.

SIf you smell any unusual odors, your unit may be oper& ating improperly. For example, units can give off unfa& miliar odors if components are required to operate in abnormal conditions.

SLook for visible signs of a malfunctioning unit. Exam& ples include unusual amounts of condensate on win& dows inside your house, visibly burnt components or unusual dirt or rust accumulations on the vent pipe or in the unit.

SIf you experience headache, nausea, fatigue, or dizzi& ness, the cause could be exposure to carbon monox& ide 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.

Unit appearance - Must be inspected for rust, dirt, signs of water, burnt or damaged wires, or components.

Fan access door - Must be properly in place and provide a seal between the return air and the room where the fur& nace is installed.

Return air duct - Must be properly attached and provide an air seal to unit.

Operating performance - Unit must be observed during operation to monitor proper performance of the unit and the vent system.

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 be& tween annual furnace inspections that may result in un& safe operation. For instance, items innocently stored next to the furnace may obstruct the combustion air supply. This could cause incomplete combustion and the produc& tion of carbon monoxide gas.
