Use & Care Manual

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.
3. Inspect the gas burners for dirt,
rust, or scale.
IF DIRT, RUST, SOOT OR SCALE
A
CCUMULATIONS 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.
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
NOT OPERATE THIS FURNACE.
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
deterioration 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.
ROUTINE MAINTENANCE
Routine maintenance to be provided
b
y a qualified installer, service
agency or the gas supplier ONLY.
LUBRICATION
The blower motor and induced draft
motor are prelubricated by the
manufacturer and do not require
further attention.
DISCONNECT MAIN ELECTRICAL
POWER TO THE UNIT BEFORE
ATTEMPTING ANY MAINTENANCE.
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, the air filters
should be kept clean because dirty
filters can restrict airflow and the motor
depends upon sufficient air flowing
across and through it to keep from
overheating
