IMPORTANT INFORMATION
Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas 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 rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is 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 of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

AFE18-60A N/A
Fossil Fuel Kit. The AFE18-60A control is designed for use where the indoor coil is located
above/downstream of a gas or fossil fuel furnace when used with a heat pump. It will operate
with single and two stage heat pumps and single and two stage furnaces. The AFE18-60A
control will turn the heat pump unit off when the furnace is turned on. An anti-short cycle feature
initiates a 3 minute timed off delay when the compressor goes off.

installed on LP gas listed in this manual.This kitincludes harness adaptors to work with
White-Rodgers single &two stage gas valves,Honeywell single and two-stage gas valves,
as well as modulating gas valves.
LPT-06 N/A
LP Conversion Kit. This kit converts only two-stage gas fired units from natural to propane
gas.This kitsupports both White-Rodgers and Honeywell two stage valves. The
conversion from natural gas (as shipped from the factory) to propane gas requires:
replacing the burner orifices, replacing gas valve regulator springs (all two stage units)
and applying identification labels. NOx screens must be removed when converting 80%
furnaces to this LP kit.

WARNING
THIS PRODUCT CONTAINS OR PRODUCES A CHEMICAL OR CHEMICALS WHICH
MAY CAUSE SERIOUS ILLNESS OR DEATH AND WHICH ARE KNOWN TO THE
STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER
REPRODUCTIVE HARM.
WARNING
TO PREVENT POSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH
DUE TO ELECTRICAL SHOCK, THE FURNACE MUST BE LOCATED TO PROTECT
THE ELECTRICAL COMPONENTS FROM WATER.
Charge (ESD) Precautions
NOTE: Discharge body’s static electricity before touching
unit. An electrostatic discharge can adversely affect elec-
tricalcomponents.
Use the following precautions during furnace installation
andservicing to protect theintegrated control module from
damage. By putting the furnace, the control, and the per-
sonat the same electrostatic potential, these stepswillhelp
avoidexposingtheintegrated controlmodule toelectrostatic
discharge. This procedure is applicable to both installed
anduninstalled(ungrounded)furnaces.
1. Disconnect all power to the furnace. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body’s electrostatic
charge to ground.
2. Firmly touch a clean, unpainted, metal surface of the
furnace near the control. Any tools held in a person’s
hand during grounding will be discharged.
3. Service integrated control module or connecting wiring
following the discharge process in Step 2. Use caution
not to recharge your body with static electricity; (i.e.,

Location Requirements and Considerations
WARNING
TO PREVENT POSSIBLE EQUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED
WHEN INSTALLING THE UNIT.
Follow the instructions listed below when selecting a fur-
nace location. Refer also to the guidelines provided in the
Combustion and Ventilation Air Requirements section in
thismanualor the installation instructions for details.
• Centrally locate the furnace with respect to the pro-
posed or existing air distribution system.
• Ensure the temperature of the return air entering the
furnace is between 55°F and 100°F when the fur-
nace is heating.
• If the furnace is installed in an application where the
typical operating sound level of a furnace is deemed
objectionable,an optionalsoundreduction kitisavail-
able. Consult your local distributor for more details.
• Provide provisions for venting combustion products
outdoors through a proper venting system. Special
consideration should be given to vent/flue pipe rout-
ing and combustion air intake pipe when applicable.
80% Furnaces: All installations must be vented in
accordance with National Fuel Gas Code, NFPA 54/
ANSIZ223.1 -latesetedition. InCanadathe furnaces
mustbe ventedinaccordance with theNationalStan-
dard of Canada, CAN/CGA B149.
• Ensureupflow or horizontalfurnacesare not installed
directly on carpeting, or any other combustible ma-
terial.The onlycombustiblematerial allowed iswood.
• A special accessory subbase must be used for up-
right counterflow unit installations over any combus-
tible material (including wood). Refer to subbase in-
structions for installation details. (NOTE: A subbase
will not be required if an air conditioning coil is lo-
cated beneath the furnace between the supply air
openingandthe combustible floor.
• Exposure to contaminated combustion air will result
in safety and performance-related problems. Do not
install the furnace where the combustion air is ex-
posedto the following substances:
chlorinatedwaxesorcleaners
chlorine-basedswimming pool chemicals
watersoftening chemicals
deicing salts or chemicals
carbontetrachloride
halogentyperefrigerants
cleaningsolutions (such as perchloroethylene)
printing inks
paintremovers
varnishes
hydrochloric acid
cementsand glues
antistatic fabric softeners for clothes dryers
andmasonry acid washing materials
• Seal off a non-direct vent furnace if it is installed
near an area frequently contaminated by any of the
above substances. This protects the non-direct vent
furnace from airborne contaminants. To ensure that
theenclosednon-directventfurnace hasan adequate
supply of combustion air, vent from a nearby uncon-
taminated room or from outdoors. Refer to the Com-
bustion and Ventilation Air Requirements section in
thismanualorthe installation instructions for details.
• If the furnace is used in connection with a cooling
unit, install the furnace upstream or in parallel with
the cooling unit coil. Premature heat exchanger fail-
ure will result if the cooling unit coil is placed ahead
of the furnace.
• If the furnace is installed in a residential garage, po-
sition the furnace so that the burners and ignition
sourcearelocatednot less than 18 inches (457 mm)
above the floor. Protect the furnace from physical
damagebyvehicles.
• If the furnace is installed horizontally, the furnace
accessdoors must be vertical so that the burners fire
horizontally into the heat exchanger. Do not install
the unit with the access doors on the “up/top” or
“down/bottom” side of the furnace.
ClearancesandAccessibility
Installations must adhere to the clearances to combustible
materials to which this furnace has been design certified.
Theminimum clearance information for this furnace is pro-
videdon the unit’s clearance label. These clearances must
be permanently maintained. Refer to Specification Sheet
for minimum clearances to combustible materials. Clear-
ances must also accommodate an installation’s gas, elec-
trical, and drain trap and drain line connections. NOTE: In
addition to the required clearances to combustible materi-
