UNIT LOCATION
1. The furnace area and the vicinity of any other gas appli-
ances must be kept clear and free of combustible mate-
rials, gasoline, and other flammable vapors and liquids.
Also, do not store or use flammable items such as paint,
varnish, or lacquer in the area.
2. Do not store or use chlorine or fluorine products
(bleaches, cements, strippers, aerosols) near the unit.
They can corrode the heat exchanger.
3. Do not use the furnace closet as storage for brooms,
mops, brushes and oily rags or cloths. The area must be
kept clear, clean and free of lint. Furnace must be kept
free and clear of exposed or loose insulation materials
in the area of installation. Examine the furnace area
when the furnace or additional insulation is added since
some insulation materials may be combustible.
4. Make sure the furnace is always connected to an ap-
proved vent, in good condition, to carry combustion prod-
ucts outdoors.
5. Familiarize yourself with the controls that shut off the
gas and electrical power to the furnace. If the furnace
is to be shut down at the end of the heating season,
turn off both the gas and electrical power. For safety,
always turn the gas and electrical power off before per-
forming service or maintenance on the furnace.
6. Establish a regular maintenance schedule to insure effi-
cient and safe operation of the furnace. The furnace
should be checked at the beginning of each heating and
cooling season by a qualified service technician.

UNIT INSTALLATION
Examine the furnace installation to determine the follow-
ing:
1. All flue product carrying passages external to the fur-
nace (i.e. chimney, vent connector) are clear and free
of obstructions.
2. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corrosion.
3. The return air duct connection is physically sound, sealed
to the furnace casing, and terminates outside the space
containing the furnace.
4. The physical support of the furnace is sound without
sagging, cracks, or gaps around the base so as to pro-
vide a seal between the support and the base.
5. There are no obvious signs of deterioration of the fur-
nace.
6. Check for proper burner flame performance. Flame
should extend directly outward from burners without
curling, floating, or lifting off.

WARNING
Improved construction and additional insulation in homes
have reduced the heat loss and made these homes much
tighter around doors and windows so that air infiltration is
minimal. This creates a problem to supply ventilation and/
or combustion air for gas fired or other fuel burning appli-
ances. Any use of appliances that pull air out of the house
(clothes dryers, exhaust fans, fireplaces, water heaters,
non-direct vent furnaces, etc.) could reduce combustion
air to the furnace.
If fuel-burning appliances are starved for air, the flue gases
produced may not vent outdoors properly. These flue gases
may include carbon monoxide.
CARBON
MONOXIDE
POISONING
HAZARD
B10259-216
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. Ifa furnace or airhandleris installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger ofCO poisoningwhich
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout thestructure if the furnace or airhandler is operating inany
mode.
CO can cause serious illness including permanent brain damage or death.
Special Warning for Installation of Furnaces or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide or “CO” is a colorless and odorless gas
produced when fuel is not burned completely or when the
flame does not receive sufficient oxygen.
Be aware of these air starvation signals which indicate
conditions that my result in carbon monoxide or that
carbon monoxide may be present:
1. Headaches, Nausea, Dizziness, Flu-like symptoms.
2. Excessive humidity, heavily frosted windows or a moist
“clammy” feeling in the home.
3. Smoke from a fireplace will not draw up the chimney.
4. Flue gases that will not draw up the appliance vent pipe.
C
OMBUSTION
A
IR
The air for combustion and ventilation can also (where lo-
cal codes permit) be obtained from the surrounding uncon-
fined space or louvered closet door. Observe the following
precautions concerning air availability:
• When a furnace is installed in a closet and the closet
door is louvered, DO NOT OBSTRUCT LOUVERS. Lou-
vers must be open and clear to provide combustion air
to the furnace.
• When a furnace is installed in a confined space within
a home and the air for combustion and ventilation en-
ters the space through ducts from the outside, be sure
to routinely check the entering and outlet, grilled open-
ings to verify that they are always clear and clean.
• Do not partition off a small area around the furnace
utilizing a non-louvered door. This could obstruct the
combustion air from reaching the furnace.

UMIDITY
Relative humidity is the amount of water vapor in the air
relative to the amount the air can hold at the same tem-
perature. The colder the air; the less moisture it can hold.
As air is warmed, its ability to hold moisture is increased.
Relative humidity is important to your health and home as
proper humidification helps reduce respiratory difficulties
and helps improve the indoor air quality.
A good relative humidity is one just high enough to barely
start condensation along the lower edges or lower corners
of the windows. More than that can be damaging.
Frequent fogging or excessive condensation on inside win-
dows indicates the indoor humidity level is too high for
outdoor weather conditions. Damage to the building may
result if the condition persists. Condensation on inside of
storm windows indicates a poor seal inside windows. Add-
ing weather-stripping to tighten inside windows usually cor-
rects this problem.
The following table shows the recommended maximum in-
door humidity in relationship to the outdoor temperatures.

UNCTIONS
There are many types and styles of thermostats but opera-
tion is usually similar. BE SURE TO BECOME FAMILIAR WITH
YOUR THERMOSTAT. The simplest type of thermostat only
starts and stops the furnace to maintain the desired room
temperature. The most widely used types will control both
heating and cooling functions and will have a Fan Switch
with Auto and ON settings. On Auto, the circulating air
blower will cycle on/off with the furnace but if switched
to ON it will run continuously regardless of whether or not
heating or cooling is being provided.
In addition, there are thermostats which automatically
switch from heating to cooling mode and those with night
set back capability. The night set back, or multiple set
back, type allows for a different temperature at night or
during the day when no one is at home. Programmable
thermostats will allow for more control and tailoring of the
heating and cooling functions. The level of this control
depends on the type of thermostat applied.

FURNACE SHUT DOWN
To shut down your furnace, follow the steps listed below.
1. Set the thermostat to the lowest setting.
2. Integrated control closes gas valve extinguishing flame.
3. Induced draft blower is de-energized following a 15 sec-
ond delay. The circulator blower is de-energized fol-
lowing a 90, 120, 150, or 180 second delay period.
4. Remove the burner compartment door.
5. Move the furnace’s gas valve ON/OFF switch to the OFF
position.
6. Close the external manual gas shut-off valve.
7. Replace the burner compartment door.
LOCKOUT RESET
Furnace lockout is characterized by a non-functioning fur-
nace (circulator blower may be running continuously) pro-
viding a diagnostic LED code. Lockout results when a fur-
nace control detects abnormal conditions. If the furnace
is in “lockout”, it may be reset by any of the following
methods:
1. One hour automatic reset. Control will automatically
reset itself and attempt to resume normal operations
following a one hour lockout period.
7
2. Power interruption. Interrupt 115 volt power to the fur-
nace for greater than 20 seconds.
3. Thermostat cycle. Interrupt thermostat signal to the
furnace for between 0 and 20 seconds.
If the condition which originally caused the lockout still
exists, the control will return to lockout. If your furnace
frequently locks out, a problem exists which must be cor-
rected. Contact a qualified servicer.

WARNING
ANNUAL INSPECTION
The furnace should be inspected by a qualified installer, or
service agency at least once per year. This check should be
performed at the beginning of the heating season by a quali-
fied technician. This will insure that all furnace compo-
nents are in proper working order and that the heating sys-
tem functions appropriately. Particular attention should
be paid to the following items. Repair or service as neces-
sary.
Check the
Burner Flames for:
1. Stable, soft and blue.
2. Not curling, floating
or lifting off.
• Flue pipe system. Check for blockage and/or leakage.
Check the outside termination and the connections at
and internal to the furnace.
• Combustion air intake pipe system (where applicable).
Check for blockage and/or leakage. Check the outside
termination and the connection at the furnace.
• Heat exchanger. Check for corrosion and/or buildup
within the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and
flame sense. Flames should extend directly outward
from burners without curling, floating or lifting off.
• Wiring. Check electrical connections for tightness and/
or corrosion. Check wires for damage.
• Drainage system. Check for blockage and/or leakage.
Check hose connections at and internal to furnace.
• Filters. Check that filters are clean and in the proper
placement in the furnace or duct system.

WARNING
A return air filter is not supplied with this furnace and can-
not be installed inside the cabinet; however, a means of
filtering all of the return air (intake) must be provided.
Your installer will supply filters at the time of installation.
Become familiar with filter location and procedures for re-
moving, cleaning and replacing them.
If you need assistance, contact the installer of your fur-
nace or another qualified servicer.
Filters must be inspected, cleaned or changed every two
months or as required. As a homeowner, it is your personal
responsibility to keep air filters clean. Remember that dirty
filters are the most common cause of inadequate heating
or cooling performance.
FILTER REMOVAL
Depending on the installation, differing filter arrangements
can be applied. Filters can be located in a central return
grille or a side panel external filter rack (upflow only). To
remove filters from an external filter rack, follow the di-
rections provided with external filter rack kit.
8
HORIZONTAL UNIT FILTER REMOVAL
Filters in horizontal installations are located in the central
return register or the ductwork near the furnace.
To remove:
1. Turn OFF electrical power to furnace.
2. Remove filter(s) from the central return register or
ductwork.
3. Replace filter(s) by reversing the procedure for removal.
4. Turn ON electrical power to furnace.
To remove all other filter configurations, consult with the
installing contractor.
MEDIA AIR FILTER OR ELECTRONIC AIR CLEANER REMOVAL
High efficiency filters are available in both electronic and
non-electronic types. These filters can do a better job of
catching small airborne particles. Contact your dealer for
further information.
If using a Media or Electronic Air Cleaner, follow the direc-
tions provided with the air cleaner for proper filter removal,
cleaning, and replacement.
FILTER CLEANING AND/OR REPLACEMENT
Disposable filters must be replaced with a filter or filters
of the same size as that which is removed. Filters must
comply with UL900 or CAN/ULC-S111 Standards.
Permanent filters must be cleaned, washed, and dried as
specified by the filter manufacturer. If it becomes neces-
sary to replace a permanent filter, it must be replaced with
a filter or filters of the same size as that which is removed.
Filters must comply with UL900 or CAN/ULC-S111 Standards.
When reinstalling filters, be careful to maintain correct
airflow direction.

ALL
If your furnace is not operating or is performing improp-
erly, take time to perform the following checks before re-
questing service. A couple of simple checks may allow you
to avoid a service call. If the following steps do not resolve
the problem, contact a qualified servicer for further trouble-
shooting and/or repairs. Do not attempt troubleshooting
beyond that which is outlined in the following bullet points.
Do not attempt repairs yourself.
• Check the blower compartment sight glass. If LED is
flashing, record the number of flashes seen in sequence,
shutdown your unit as outlined in the “Furnace Start-
up” section and contact a qualified servicer for further
troubleshooting and/or repairs. Refer to Installation
Instructions for code identification. If not flashing,
continue with checks.
• Check thermostat for proper operation. Verify that it
is set on HEAT and that temperature (above room tem-
perature) setting is appropriate.
• Check the electrical panel for tripped circuit breakers
or failed fuses. Reset the circuit breakers or replace
fuses as necessary.
• Check to see that the manual gas shut-off valve exter-
nal to the furnace is in the ON position. If the valve is

out your home. Grilles may be blocked by furniture,
drapery, clothes, carpeting, etc. Clear any blockage.
• Check intake and vent terminations on high efficiency
furnaces to make sure they are not blocked.

Special warning for installationof furnaces or air handling units in enclosed area such as garages, utility
rooms or parking areas. Carbon monoxide producing devices (such as an automobile, space heater, gas
water heater, etc.) Should not be operated in enclosed areas such as unventilated garages, utility room or
parking areas because of the danger of carbon monoxide (CO) poisoning resultingfrom the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such as garage, utility room or parking
area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation. Carbon monoxide
emissions can be (re)circulatedthroughout the structure if the furnace or air handler is operating in any mode. CO can cause serious
illness including permanent brain damage or death.
