Page 5 Service Reminder Call your Lennox service technician if the unit will not operate. Before calling, always check the following to be sure service 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, which will limit air flow. 6- Is gas turned on at meter? 7- Ismanualmainshut-offvalveopen? Record the model and serial number of the furnace. These numbers are on the unit nameplate, which is located on the blower deck below the combustion air inducer. Serial Number _ Model Number 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 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 flu because symptoms are similar. If you suffer from flu-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 qualified service technician as an investment in yourwell 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 of 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 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 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. Safety Precautions Page 6 Repair Parts List The following repair parts are available through Lennox dealers.
