Is the control knob on the gas valve turned to the ON posi-
tion? 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.
M
Check for pilot flame. If there is no pilot flame, follow the
manual start-up procedures or the furnace lighting instruction
label. If the pilot flame exists, check the control knob on the gas
valve. If the knob is in the PILOT position, turn it to ON and
complete the start-up procedures.

If for some reason the vent is blocked, the draft safeguard
switch will shut off the furnace. Reset the switch by pushing
the button located on top of the switch (see page 3 for switch
location).
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 them the model and
serial numbers for your furnace. (You should have them re-
corded on page 2 of this booklet.) If the dealer knows exactly
which furnace you have, they 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 will-
ing to do, your furnace should be inspected regularly by a prop-
erly trained service technician. An annual inspection (or every
other year, at least) should include the following:
1. Inspection of all flue product passages—including the
burners, pilot and pilot tube, heat exchanger, relief box, 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 for leaks and/or deterioration.
4. Inspection, cleaning, and lubrication (when required) of the
blower motor and wheel.
NOTE:
Refer to the unit service procedures for blower motor
oiling information. When required, the motor must be oiled by
a qualified service technician.
5. Routine inspection and cleaning/replacement of the air fil-
ter(s).
6. Inspection of all supply- and return-air ducts for obstruc-
tions, air leaks, and insulation. Any problems found should
be resolved at this time.
7. A check for loose connections attaching individual compo-
nents. Inspection of all electrical wiring and their connec-
tions.
8. Operational check of the furnace itself to determine work-
ing condition. Repair or adjustment should be made at this
time.
9. Check the physical support around the furnace base for
cracks, gaps, sagging etc. Ensure there is a good air seal
between the furnace and support.
10. Check burner and pilot flames. Compare flames to Fig. 18
for proper operation.
Your servicing dealer offers an economical service contract that
covers seasonal inspections. Ask him for further details.
