IMPORTANT INFORMATION
Speci al War ning for Inst allation of Furnace or Air Handling Units in Enclosed A reas such as Garage s, Utility Ro oms or Parki ng A r eas
Carbon monoxide producing devic es (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as un ve n tilated garages, ut ility rooms or parking areas because of the danger of c a rbon monoxide (CO) poison ing resulting from the exha ust 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)circu l a ted throughout the structure if t he furnace or air han dler is operating in any mode.
CO can cause serious illness in clud ing per man e nt brain dama ge or deat h.

WARNING
TO PREVENT POSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH
DUE TO ELECTRICAL SHOCK, THE FURNACE MUST BE LOCATED TO PROTECT THE ELEC TRICA L COMPON ENTS FROM WAT ER.
Charge (ESD) Precautions NOTE: Discharge body’s static electricity before touching
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 control on a furnace. Return any old or new controls to their containers before touching any ungrounded object.

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 EQUI PMENT DAMAGE, PROPERTY DAMAGE, PERSONAL
T
INJURY OR DEATH, THE FO LLOWING 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.
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.
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-direct vent furnace from airborne contaminants. To ensure that the en­closed non-direct vent furnace has an adequate sup- ply of combustion air, vent from a nearby uncontami­nated room or from outdoors. Refer to the Combus- tion 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.
If the furnace is installed horizontally, the furnace ac­cess doors 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.
Clearances and Accessibility
Installations must adhere to the clearances to combustible materials to which this furnace has been design certified. The minimum clearance information for this furnace is pro­vided on the unit’s clearance label. These clearances must be permanently maintained. Refer to Specification Sheet for minimum clearances to combustible materials. Clearances must also accommodate an installation’s gas, electrical, and drain trap and drain line connections. NOTE: In addition to the required clearances to combustible materials, a mini­mum of 24 inches service clearance must be available in front of the unit.
A furnace installed in a confined space (i.e., a closet or utility room) must have two ventilation openings with a total minimum free area of 0.25 square inches per 1,000 BTU/hr of furnace input rating. One of the ventilation openings must be within 12 inches of the top; the other opening must be within 12 inches of the bottom of the confined space. In a typical construction, the clearance between the door and door frame is usually adequate to satisfy this ventilation re­quirement.

Furnace Suspension
If suspending the furnace from rafters or joist, use 3/8" threaded rod and 2”x2”x1/8” angle iron as shown in the fol­lowing figure. If the furnace is installed in a crawl space it must also be suspended from the floor joist or supported by a concrete pad. Never install the furnace on the ground or allow it to be exposed to water. The length of rod will depend on the application and the clearances necessary.

EXISTING FURNACE REMOVAL
NOTE: When an existing furnace is removed from a venting
system serving other appliances, the venting system may be too large to properly vent the remaining attached appli­ances.
The following vent testing procedure is reproduced from the
American National Standard/National Standard of Canada for Gas-Fired Central Furnaces ANSI Z21.47, latest edition, CSA-2.3b, latest edition Section 1.23.1.
The following steps shall be followed with each appliance connected to the venting system placed in operation, while any other appliances connected to the venting system are not in operation:
a. Seal any unused openings in the venting system; b. Inspect the venting system for proper size and horizon-
tal pitch, as required by the National Fuel Gas Code, ANSI Z223.1 or the CSA B149 Installation Codes and these instructions. Determine that there is no block­age or restriction, leakage, corrosion and other defi­ciencies which could cause an unsafe condition;
c. In so far as practical, close all building doors and
windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers;
d. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust thermostat so appliance shall operate continuously;
e. Test for draft hood equipped spillage at the draft hood
relief opening after 5 minutes of main burner operation. Use the flame of a match or candle;
f. After it has been determined that each appliance
connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use;
g. If improper venting is observed during any of the above
tests, the common venting system must be corrected.
Corrections must be in accordance with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 and/or CSA B149 Installation Codes.
If resizing is required on any portion of the venting system, use the appropriate table in Appendix G in the latest edition of the National Fuel Gas Code ANSI Z223.1 and/or CSA B149
Installation Codes.
Thermostat Requirements
To use a single-stage thermostat, turn off power to the fur­nace, move the thermostat selection DIP switch to the OFF position. Set the desired transition time by setting the tran­sition delay DIP switch to the desired ON/OFF position. Turn power back on.
NOTE: The GME8 and AMEH8 hybrid furnaces require a single stage thermostat. These furnaces utilize a control board with single stage or two stage capability. The second stage feature is established by setting a dip switch on the board, either one stage or two stage. All of the second stage timing is then controlled by dipswitch 3 on the circuit board.

COMBUSTION AND VENTILATION AIR REQUIREMENTS
WARNING
OSSIBLE PROPERTY DAMAGE , PERSONAL I NJURY OR DEAT H MAY OCCUR
P
IF THE FURNAC E IS NOT P ROVIDED WITH ENOUGH FRESH AIR FOR PROP ER COMBUSTION AND VENTILAT ION OF FLUE GASES. MOST HOMES REQUI RE OUTSIDE AIR BE SUPPLIED TO THE FURNACE AREA.
Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and es­cape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a prob­lem supplying combustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air.
If this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for the other appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 (Section 9.3), or CAN/ CGA B149 Installation Codes (Sections 7.2, 7.3, or 7.4), or applicable provisions of the local building codes for deter­mining the combustion air requirements for the appliances.
Most homes will require outside air be supplied to the fur­nace area by means of ventilation grilles or ducts connect­ing directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces.
The following information on air for combustion and ventila­tion is reproduced from the National Fuel Gas Code NFPA
54/ANSI Z223.1 Section 9.3.
