*The Thermo Products supplied filter can be cut to size to fit other filter retention systems as long as the minimum size requirement is met. NOTICE: Any internal stiffeners used in the filter must not be removed, although they can be cut to the length required.

C. VISUAL INSPECTION PROCEDURE

It is recommended that the homeowner/user conduct the following periodic visual inspection of the furnace at the start of the heating season and monthly during the heating season.

: Call a qualified heating contractor to report suspected deficiencies (Do not attempt to make repairs yourself!)

1.Turn off power to furnace.

2.Vent pipe, air intake pipe, and condensate system (CDB1/CHB1, CDX1/CHX1): Visually check the vent and intake pipe as well as condensate lines both inside and outside the furnace to make sure that vent intake joints and the condensate system are sealed. There should be no sign of water leakage at any vent intake or condensate joints or anywhere inside the furnace. Make sure that horizontal runs of vent pipe slope upward towards the outside. The inlet pipe should slope slightly downward to prevent condensate build up. Any signs of damage, leakage, deterioration, or possible blockage should be immediately reported to your dealer or

the local gas company.

It is recommended that the condensate removal system be cleaned annually by a qualified service agency to insure its proper and continued operation.

Outside vent and outside combustion air termination: the outside vent terminations should be inspected to insure that they are clear and free of obstruction by ice, snow, debris, of vegetation. Any obstruction of the terminal should be carefully removed without damaging the vent terminal. If ice has formed on the outside terminals themselves, it should be removed.
