Venting System Inspection

Annually (before heating season) inspect furnace venting system, vent cap, heat exchanger and burners for corro- sion, deterioration, or deposits of debris. Remove any ob- structions.

Contact your Lennox dealer for a periodic unit inspection by a qualified service technician.

Flame Rollout Safety Switches

Your Lennox furnace is equipped with two flame roll-out safety switches which shut off the gas supply to the fur- nace in case of heat exchanger blockage. If the furnace fails to operate due to the functioning of these safety switches, DO NOT attempt to place the furnace into op- eration. Contact a qualified service technician.

Service Reminder

Call your Lennox service technician if unit is inoperative. Before calling, always check the following to be sure ser- vice is required.

1 - Check that electrical disconnect switches are ON.

2 - Check room thermostat for proper setting.

3 - Replace any blown fuses or reset circuit breakers. 4 - Gas valve should be ON.

5 - Air filter should not be plugged limiting air flow.

6 - Is gas turned on at meter?

7 - Is manual main shut-off valve open?

To keep your Lennox gas heating system in peak operat- ing condition year after year, contact your independent Lennox dealer about a planned service program.

Safety Precautions

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

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 oper- ating improperly. For example, units can give off unfa- miliar odors if components are required to operate in

:abnormal conditions.

Look 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.

:If 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.

Planned Service

You should expect a service technician to check the fol- lowing 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 unob- structed to provide combustion air.

Burners- Must be inspected for rust, dirt, or signs of wa- ter.

Vent pipe - Must be inspected for signs of water, dam- aged or sagging pipe, or disconnected joints.

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.

Combustion gases - Flue products must be analyzed and compared to the unit specifications.

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.
