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. 14 All installations and services must be performed by qualified service personnel. 3. Flue Pipe Connection & Chimney for MDA1/MHA1: Visually check flue pipe and chimney for tightness, blockage and corrosion. If fittings are loose or if blockage or corrosion is suspected to be a problem, contact a qualified heating contractor. Make sure horizontal runs of the flue have an upward slope away from furnace of 1/4" per foot minimum and are physically sound without holes, cracks or signs of corrosion. There should be no sign of moisture or vent gas leakage at any vent connection. ADDITIONAL REQUIREMENTS OF FURNACES VENTED THROUGH THE SIDE OF THE HOUSE WITH NO CHIMNEY. a. Such horizontally vented furnaces should also be inspected to make sure that all vent joints are sealed and that the outside vent terminal is clear and free of obstruction by ice, snow or debris. Any obstruction of the terminal should be carefully removed without damaging the vent terminal. If ice has formed on the terminal itself, it should be removed using a blow dryer. b. The sidewall venting kit (SWGII Power Vent...
