At the beginning of each heating season, the system should be checked as follows:

1- Examine the termination ends of the intake and ex- haust lines for obstructions or blockages.

2- Check the intake and exhaust lines for holes, sag- ging or broken isolation hangers. If a sag is found in either line, raise the line and support it with an isola- tion hanger. Replace any damaged isolation hang- ers.

3- The return air duct connection should be sealed to the furnace casing and terminate outside the space containing the furnace.

4- Check the physical support of the furnace. It should be sound without sagging, cracks, gaps, etc., around the base so as to provide a seal between the support and the base.

5- Check that there is no obvious signs of deterioration of the furnace.

6- Inspect and clean condensate drain system for free flow of condensate.

Call your Lennox service technician if the unit is inop- erative. Before calling, always check the following to be sure service is required:

1- Be sure electrical switches are ON.

-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

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.

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 unob- structed to provide combustion air.

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

Vent pipe - Must be inspected for dirt, signs of water, dam- aged or sagging unsupported 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 airtight seal to the unit.

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

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