FAILURE TO DO SO CAN RESULT
IN ELECTRICAL SHOCK, SEVERE
PERSONAL INJURY OR DEATH.
The blower compartment and motor
should be inspected and cleaned
periodically by your qualified installer,
service agency or the gas supplier to
prevent the possibility of overheating
due to an accumulation of dust and dirt
on the windings or on the motor
exterior. And, as suggested elsewhere
in these instructions, keep the air filters
clean because dirty filters can restrict
airflow and the motor depends upon
sufficient air flowing across and
through it to keep from overheating
COMBUSTION AREA AND VENT
SYSTEM
1. It is recommended that an annual
inspection of your furnace be
done by a qualified installer,
service agency or the gas
supplier.
2. Turn OFF the electrical supply to
the furnace and remove the
access doors.

IF DIRT, RUST, SOOT OR SCALE
ACCUMULATIONS ARE PRESENT,
DO NOT OPERATE THE FURNACE.
INSPECT THE HEAT EXCHANGERS
FOR LEAKS. LEAKS CAN CAUSE
TOXIC FUMES TO ENTER THE
HOME RESULTING IN CARBON
MONOXIDE POISONING OR DEATH.
4. Inspect the the flue connection
area and vent pipe. Be sure that
the vent connector is in place and
slopes upward and is physically
sound, without holes or excessive
corrosion.
WARNING
!
IF HOLES ARE FOUND IN THE VENT
PIPE, OR IF IT HAS BECOME
DISCONNECTED, TOXIC FUMES
CAN ESCAPE INTO THE HOME
RESULTING IN CARBON MONOX-
IDE POISONING OR DEATH. DO

APPROPRIATE SERVICE MUST BE
APPLIED.
5. Be sure that the return air duct
connections are physically sound,
are sealed to the furnace casing
and terminate outside the space
containing the furnace.
6. Be sure the physical support of the
furnace is sound, without sags,
cracks, etc., around the base so
as to provide a seal between the
support and the base.
7. Look for obvious signs of deterio-
ration of the furnace.
8. If the furnace is free of the above
conditions, replace the access
doors and restore electrical power
to the furnace.
9. Start the furnace and observe its
operation. Watch the burner
flames to see if they are bright
blue. If a suspected malfunction is
observed, or the burner flames
are not bright blue, apply
appropriate service.
MARKINGS
It is recommended that an annual
inspection and cleaning of all furnace
markings be made to assure legibility.
Attach a replacement marking, which
can be obtained through the distributor,
if any are found to be illegible or
missing.
