The blower compartment and motor should be inspected and cleaned periodically by your qualified installer, service agency or the gas supplier to prevent the possibility of overheating due to an accumulation of dust and dirt on the windings or on the motor exterior. And, as suggested elsewhere in these instructions, the air filters should be kept clean because dirty filters can restrict airflow and the motor depends upon sufficient air flowing across and through it to keep from overheating

COMBUSTION AREA AND VENT SYSTEM

  1. It is recommended that an annual inspection of your furnace be done by a qualified installer, service agency or the gas supplier.

  2. Turn OFF the electrical supply to the furnace and remove the access doors.

  3. Inspect the gas burners for dirt, rust, or scale and clean as necessary.
    WARNING
    IF DIRT, RUST, SOOT OR SCALE ACCUMULATIONS ARE PRESENT, DO NOT OPERATE THE FURNACE. INSPECT THE HEAT EXCHANGERS FOR LEAKS. LEAKS CAN CAUSE TOXIC FUMES TO ENTER THE HOME AND CAUSE CARBON MONOXIDE POISONING OR DEATH.

  4. Inspect the flue connection area and vent pipe. Be sure that the vent connector is in place and slopes upward and is physically sound, without holes or excessive corrosion.

  5. Be sure that the return air duct connections are physically sound, are sealed to the furnace casing and terminate out-side the space containing the furnace.

  6. Be sure the physical support of the furnace is sound, with-out sags, cracks, etc., around the base so as to provide a seal between the support and the base.

  7. Look for obvious signs of deterioration of the furnace.

  8. If the furnace is free of the above conditions, replace the ac-cess doors and restore electrical power to the furnace.

  9. Start the furnace and observe its operation. Watch the burner flames to see if they are bright blue. If a suspected malfunction is observed, or the burner flames are not bright blue, apply appropriate service.

CONDENSATE
NOTE: This furnace is equipped with a pressure switch which will shut off the main burners if the condensate drain line be-comes blocked.
Be sure this condensate drain line does not become blocked or plugged. Visual inspection of condensate flow can easily be made while the furnace is in operation. A flashlight can be used to illuminate the discharge end placed in the sewer openings.
Clean and flush the condensate tube to make sure condensate flows freely while the furnace is in operation.
If a means to neutralize the condensate has been provided for the furnace, be sure to follow the maintenance schedule fur-nished by the manufacturer.
