NOTE: If dirt, rust, soot, or scale accu- mulations are found, call your servic- ing dealer. DO NOT OPERATE THE FURNACE.

3.Inspect the vent pipe for a sag, holes, or a disconnection. A hori- zontal vent pipe must slope up- ward. If rusty joints or seams, or signs of water leakages are found call your dealer for service.

!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 FUR- NACE. Call your dealer for ser- vice. A failure to follow this warning could result in per- sonal injury or death.

4.Replace the access doors and re- store electrical power to the fur- nace. Be sure bottom door flange is inside of the furnace casing. (See Fig. 16, 17, and 26.)

5.Start the furnace and observe its operation. If possible, watch the burner flames. Are they burning bright blue? If not (or if you suspect some other malfunction), call your servicing dealer.

BEFORE YOU REQUEST A “SERVICE CALL”

BEFORE YOU CALL FOR SERVICE, CHECK FOR SEVERAL EASILY SOLVED PROBLEMS:

•Check for sufficient airflow. Check the air filter for dirt. Check for blocked re- turn-air or supply-air grilles. Be sure they are open and unobstructed. If this isn’t the cause, call your servicing dealer.

If your furnace isn’t operating at all, check the following list for easily solved problems:

•Is your thermostat set above room temperature? Is the HEAT mode selected?

•Is the electrical power supply switch ON? Is the blower access door firmly in place? Are any fuses blown? (There is a fuse on the furnace control board.)

Has a circuit breaker tripped?

•Is the manual shutoff valve in the gas supply pipe leading to the furnace
