1. GENERAL INSPECTION – Examine the furnace installation
for the following items:
a. All flue product carrying areas external to the furnace
(i.e. chimney, vent connector) are clear and free of
obstruction.
b. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
c. The return air duct connection(s) is physically sound, is
sealed to the furnace and terminates outside the space
containing the furnace.
d. The physical support of the furnace should be sound
without sagging, cracks, gaps, etc., around the base so
as to provide a seal between the support and the base.
e. There are no obvious signs of deterioration of the
furnace.
f. The burner flames are in good adjustment without
erratic flames. See illustration below.
g. Fresh air inlet and vent are not blocked and free from
obstruction. The horizontal or vertical vent and inlet
must be located at least 12 inches minimum (18 inches
in Canada) above the normally expected snow
accumulation level.
Contact your service agent if you feel you are uncomfortable
performing any of the inspections noted in section 1.
2. BLOWERS – The blower size and speed determine
the air volume delivered by the furnace. The blower
motor bearings are factory lubricated and under normal
operating conditions usually do not require servicing.
Annual cleaning of the blower wheel and housing is
recommended for maximum air output, and this must be
performed only by a qualified servicer or service agency.
3. IGNITER – This unit has a special hot surface direct ignition
device that automatically lights the burners. Please note
that it is very fragile and should be handled with care.
For regular dealer maintenance please refer to

To ensure proper operation of your furnace, the
recommended dealer inspection is once a year, before the
heating season. Regular maintenance must be performed by
a qualified service professional.
The servicer should perform steps 1–9 once a year before
the heating season.
The homeowner should perform the visual inspection in step
1 monthly when cleaning the furnace filter.
Unless it is an emergency, never stop the heating system by
shutting off the main power.
If the main power to your air conditioner is ever disconnected
for more than three hours, turn off the thermostat. Then wait
for at least three more hours after the power has been restored
before turning the thermostat back on. Failure to follow this
procedure could result in damage to your furnace.
