TATE OF CALIFORNIA TO CAUSE CANCER, BI RTH DEFECTS OR OTHER
REPRODUCTIVE HARM.
WARNING
TO PREVENT POSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH
DUE TO ELECTRICAL SHOCK, THE FURNACE MUST BE LOC ATED TO PROTECT THE ELEC TRICA L COMPON ENTS FROM WA TER.
Charge (ESD) Precautions NOTE: Discharge body’s static electricity before touch-
ing unit. An electrostatic discharge can adversely affect electrical components.
Use the following precautions during furnace installa­tion and servicing to protect the integrated control mod­ule from damage. By putting the furnace, the control, and the person at the same electrostatic potential, these steps will help avoid exposing the integrated control module to electrostatic discharge. This procedure is ap­plicable to both installed and uninstalled (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., do not move or shuffle your feet, do not touch ungrounded objects, etc.). If you come in contact with an ungrounded object, repeat Step 2 before touching control or wires.
4. Discharge any static electricity from your body to ground before removing a new control from its con­tainer. Follow Steps 1 through 3 if installing the con-
trol on a furnace. Return any old or new controls to their containers before touching any ungrounded ob­ject.
Product Application
This product is designed for use as a residential home gas furnace. It is not designed or certified for use in mobile home, trailer, or recreational vehicle applica­tions.
This furnace can be used in the following non-industrial commercial applications: Schools, Office buildings, Churches,
Retail stores, Nursing homes, Hotels/motels, Common or office areas. In such applications, the furnace must be installed
with the
Goodman® & Amana
installation instructions.
®
Brand 80% furnaces are ETL certi­fied appliances and are appropriate for use with natural or propane gas. (NOTE: If using propane gas, a propane conversion kit is required).
IMPORTANT NOTE: The 80% furnace cannot be in­stalled as a direct vent (i.e.., sealed combustion) fur­nace. The burner box is present only to help reduce sound transmission from the burners to the occupied space.
To ensure proper installation, operation and servicing, thoroughly read the installation and service manuals for specifics pertaining to the installation, servicing and application of this product.
WARNING
OSSIBLE PROPERTY D AMAGE, PERSONAL INJ URY OR DEATH DUE TO FIRE,
P
EXPLOSION, SMOKE, S OOT, CONDENSTAION, E LECTRICAL SHOCK OR C ARBON MONOXIDE MAY RESULT FROM IMPROPER INSTALLATION, RE PAIR, OPERATI ON, OR MAINTENANCE OF THI S PRODUCT.
WARNING
T
O PREVENT PROPERTY DAMAGE, PERSONAL INJ URY OR DEATH D UE TO FIRE, DO NOT INSTALL THIS FURNACE IN A MOBILE HOME, TRAILER, OR RECREATIONAL VEHICLE.
To ensure proper furnace operation, install, operate, maintain and service the furnace in accordance with the installation, operation and service instructions, all lo­cal building codes and ordinances. In their absence, fol­low the latest edition of the National Fuel Gas Code (NFPA 54/ANSI Z223.1), and/or CAN/CGA B149 Installa­tion Codes, local plumbing or waste water codes, and other applicable codes.
A copy of the National Fuel Gas Code (NFPA 54/ANSI
Z223.1) can be obtained from any of the following:

The rated heating capacity of the furnace should be greater than or equal to the total heat loss of the area to be heated. The total heat loss should be calculated by an approved method or in accordance with “ASHRAE Guide” or “Manual J-Load Calculations” published by the Air Conditioning Contractors of America.
Location Requirements and Considerations
WARNING
O PREVENT POSSIBLE E QUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL
T
INJURY OR DEATH, THE FOLLOWING BULLET P OINTS MUST BE OBSERVED WHEN INSTALLING THE UNIT.
Follow the instructions listed below when selecting a furnace location. Refer also to the guidelines provided in the Combustion and Ventilation Air Requirements sec­tion in this manual or the installation instructions for details.
Centrally locate the furnace with respect to the proposed or existing air distribution system.
Ensure the temperature of the return air entering the furnace is between 55°F and 100°F when the furnace is heating.
If the furnace is installed in an application where the typical operating sound level of a furnace is deemed objectionable, an optional sound reduc­tion kit is available. 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 routing and combustion air intake pipe when applicable.
80% Furnaces: All installations must be vented in accordance with National Fuel Gas Code, NFPA 54/ ANSI Z223.1 - lateset edition. In Canada the fur­naces must be vented in accordance with the Na­tional Standard of Canada, CAN/CGA B149.
Ensure upflow or horizontal furnaces are not in­stalled directly on carpeting, or any other com­bustible material. The only combustible material allowed is wood.
A special accessory subbase must be used for up­right counterflow unit installations over any com­bustible material (including wood). Refer to sub­base instructions for installation details. (NOTE: A subbase will not be required if an air condition­ing coil is located beneath the furnace between the supply air opening and the 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 exposed to the following substances:
chlorinated waxes or cleaners chlorine-based swimming pool chemicals water softening chemicals deicing salts or chemicals carbon tetrachloride halogen type refrigerants cleaning solutions (such as perchloroethylene) printing inks paint removers varnishes hydrochloric acid cements and glues antistatic fabric softeners for clothes dryers and masonry 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-di- rect vent furnace from airborne contaminants. To ensure that the enclosed non-direct vent furnace has an adequate supply of combustion air, vent from a nearby uncontaminated room or from out­doors. Refer to the Combustion and Ventilation Air Requirements section in this manual or the 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 failure will result if the cooling unit coil is placed ahead of the furnace.
If the furnace is installed in a residential garage, position the furnace so that the burners and igni­tion source are located not less than 18 inches (457 mm) above the floor. Protect the furnace from physical damage by vehicles.
