A CAUTION:
If dirt, rust, soot, or scale accumulations are found, call your servicing dealer. DO NOT
OPERATE THE FURNACE.
3. Inspect the vent pipe for a sag, holes, or a disconnection. A horizontal vent pipe must slope upward away from furnace. If
rusty joints or seams, or signs of water leakages are found, call your dealer for service.
4. Restore electrical power to the furnace. (See Fig. 12.)
5. Start the furnace and observe its operatiom If possible, watch the burner flames. Are they burning bright blue? If not or if you
suspect some other malfunction, call your servicing dealer.
6. Replace the access door. (See Fig. 11.)
BEFORE YOU REQUEST A "SERVICE CALL"
Before you call for service, check for several easily solved problems:
• Check for sufficient airflow. Check the air tilter for dirt. Check for blocked return-air or supply-air grilles. Be sure they are
open and unobstructed. If this isn't the cause of the problem, 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.) Has a circuit breaker tripped?
• Is the manual shut-off valve in the gas supply pipe leading to the furnace open? Does the lever point in the same direction that
the pipe runs (open)? Or is it at a right angle to the pipe (closed)'?
NOTE: Before proceeding with the next checks, turn off the electrical power supply m the furnace. Remove access door.
• Is the switch on the gas valve turned to the ON position? If this or the preceding check shows an interruption in the gas supply,
make sure the gas has not been shut off for safety reasons. If nothing else seems m be wrong, follow the startup procedures found
on pages 4 and 5 of this booklet.
CAUTION:
If for some reason the vent is blocked, the draft safeguard switch will shut off the furnace.
(See page 2 or 3 for switch location.)The switch will automatically reset after the furnace cools off. If the
furnace fails to operate, contact a qualified service agency.
• Check the lnauual reset limit switches located on the ends of the burner enclosures (See Fig. 2). If the _ruace has experienced
a high-temperature condition due to inadequate combustion air, these switches will shut off the furnace. Reset the switches by
pushing the button on the switch. If the switch trips a second time, turn off the furnace and call for service.
• If your furnace still fails to operate, call your servicing dealer for troubleshooting and repairs. Tell your dealer the model and
serial numbers for your furnace. (You should have them recorded on page 8 of this booklet.) By knowing exactly which furnace
you have, the dealer may be able to offer suggestions over the phone or save valuable time through knowledgeable preparation for
the service call.
REGULAR DEALER MAINTENANCE
In addition to the type of routine maintenance you might be willing to do, your furnace should be inspected regularly by a properly
trained service technician. A semiannual inspection (or annual inspection, at least) should include the following:
1. Inspection of all flue gas passages including the burners, heat exchanger, inducer, elbow, and vent pipe.
2. Inspection of all combustion and ventilation air passages and openings.
3. Close check of all gas pipes leading to and inside of your furnace.
