Annual Inspection

The furnace should be inspected by a qualified installer,

in proper working order and that the heating system
functions appropriately. Particular attention should be
paid to the following items. Repair as necessary.
• Flue pipe system. Check for blockage and/or leak-
age. Check the outside termination and the con-
nections at and internal to the furnace.

cable). Check for blockage and/or leakage. Check
the outside termination and the connection at the
furnace.
• Heat exchanger. Check for corrosion and/or
buildup within the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame,
and flame sense. Flames should extend directly
outward from burners without curling, floating or lift-
ing off.
• Drainage system. Check for blockage and/or leak-
age. Check hose connections at furnace.
• Wiring. Check electrical connections for tightness
and/or corrosion. Check wires for damage.
• Filters. Check that filters are clean and in the
proper placement in the furnace or duct system.
