COMBUSTION AREA AND VENT SYSTEM
WARNING:
If holes are found or if the vent pipe is obstructed or is not connected, toxic fumes can
escape into your home. DO NOT OPERATE YOUR FURNACE. Call your dealer for service. A failure to follow
this warning could result in personal injury or death.
WARNING:
For proper and safe operation the furnace needs air for combustion and ventilation. Do not
block or obstruct air openings on the furnace, air opening to the area in which the furnace is installed, and the
space around the furnace.
Inspect the Colnbustion area and vent system before each heating season. An accumulation of dirt, soot, or rust can mean a
loss of efficiency and improper performance. Buildups on the main burners can cause faulty firing. This "delayed ignition" is
characterized by an alarmingly loud sound.
NOTE: If your furnace makes a loud noise when the main burners are ignited, shut down the furnace and call your servicing
dealer.
Use your flashlight and follow these steps for inspecting the combustion area and vent system of your furnace:
1. Turn off electrical supply to the furnace and remove the access door. (See Fig. 7 and 8.)
2. Carefully inspect the gas burner for dirt, rust, or scale (See Fig. 17.) Inspect the elbow, flue connection
area, and the vent pipe for rest.
