WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
If dirt, rust, soot, or scale accumulations are found, call
your dealer. Do not operate your 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.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
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.
4. Restore electrical power to the furnace. (See Fig. 10.)
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.
6. Replace the access door. (See Fig. 9.)
BEFORE YOU REQUEST A
"SERVICE CALL"
Before you call for service, check for several easily solved
problems:
S Check for sufficient airflow. Check the air filter 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:
S Is your thermostat set above room temperature? Is the HEAT
mode selected?
S 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?
S 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 to the furnace. Remove access door.
S 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 to be wrong, follow the start- -up procedures
found on pages 4 and 5 of this booklet.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in personal injury.
If for some reason the vent is blocked, the draft safeguard
switch will shut off the furnace. (See Page 2 for switch
location.) The switch will automatically reset after the furnace
cools off. If the furnace fails to operate, contact a qualified
service agency.
S Check the manual reset limit switches located on the ends of the
burner enclosure (see Fig. 1 and 2). If the furnace 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.
S 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.
