Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. Goodman will not be responsible for any injury or property damage arising from improper service or service procedures. If you install or perform service on this unit, you assume responsibility for any personal injury or property damage which may result. Many jurisdictions require a license to install or service heating and air conditioning equipment. WARNING 2 Installation and repair of this unit should be performed ONLY by individuals meeting the requirements of an "entry level technician", at a minimum, as specified by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). Attempting to install or repair this unit without such background may result in product damage, personal injury or death.

Failure to follow these regulations may harm the environment and can lead to the imposition of substantial fines. These regulations may vary by jurisdiction. Should questions arise, contact your local EPA office. Do not connect or use any device that is not design certified by Goodman for use with this unit. Serious property damage, personal injury, reduced unit performance and/or hazardous conditions may result from the use of such non-approved devices. WARNING To prevent the risk of property damage, personal injury, or death, do not store combustible materials or use gasoline or other flammable liquids or vapors in the vicinity of this appliance. WARNING 3 PRODUCT DESIGN General Operation Models covered by this manual come with a new 4-wire communicating PCB. When paired with a compatible communicating indoor unit and a CTK0* communicating thermostat, these models can support 4-wire communication protocol and provide more troubleshooting information. These models are also backward compatible with the legacy thermostat wiring. Notes: The GCVC9, GCVC95, GMVC95, AMVC95 and ACVC95 furnaces are equipped with an electronic ignition device to light the burners and an induced draft blower to exhaust combustion products. 2. Line voltage wiring can enter through the right or left side of the furnace. Low voltage wiring can enter through the right or left side of furnace. An interlock switch prevents furnace operation if the blower door is not in place. Keep the blower access doors in place except for inspection and maintenance. These furnaces are also equipped with a self-diagnosing electronic control module. In the event a furnace component is not operating properly, the control module's dual 7-segment LED's will display an alpha-numeric code, depending upon the problem encountered. For information regarding diagnostics and LED codes refer to the Installation Instructions shipped with the furnace or the service manual .PDF available at www.goodmanmfg.com or www.amana-hac.com. 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. 1. Installer must supply one or two PVC pipes: one for combustion air (optional) and one for the flue outlet (required). Vent pipe must be either 2” or 3” in diameter, depending upon furnace input, number of elbows, length of run and installation (1 or 2 pipes). The optional Combustion Air Pipe is dependent on installation/code requirements and must be 2” or 3” diameter PVC. 3. Conversion kits for propane gas and high altitude natural and propane gas operation are available. See High Altitude Derate chart for details. 4. Installer must supply the following gas line fittings, depending on which entrance is used: Left -- Two 90° Elbows, one close nipple, straight pipe Right -- Straight pipe to reach gas valve. Accessibility Clearances (Minimum) *MVC95* MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS (INCHES) POSITION* FRONT The furnace should be as centralized as is practical with respect to the air distribution system. • Do not install the furnace directly on carpeting, tile, or combustible material other than wood flooring. • When suspending the furnace from rafters or joists, use 3/8" threaded rod and 2” x 2” x 1/8” angle as shown in the Installation and Service Instructions. The length of the rod will depend on the application and clearance necessary. • FLUE FLOOR 3 0 0 1 0 C Alcove 6 0 4 0 C *= All positioning is determined as installed unit is viewed from the front. C= If placed on combustible floor, floor MUST be wood only. NC= For instalaltion on non-combustible floors only.

Alcove Illustration REAR SIDE When installed in a residential garage, the furnace must be positioned so the burners and ignition source are located not less than 18 inches (457 mm) above the floor and protected from physical damage by vehicles.

Note: In all cases accessibility clearance shall take precedence over clearances from the enclosure where accessibility clearances are greater. All dimensions are given in inches. 4 PRODUCT DESIGN High Altitude Derate When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be installed. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range. High altitude kits are purchased according to the installation altitude and usage of either natural or propane gas. Refer to the chart below for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude Natural Gas and Propane Gas kits. For a tabular listing of appropriate altitude ranges and corresponding manufacturer's High Altitude Pressure Switch kits, refer to either the Pressure Switch Trip Points & Usage Chart in this manual or the Accessory Charts in Service Instructions.

The airflow (rounded to the nearest 100 CFM) is displayed on the dual 7-segment LED's. The CFM display alternates with the operating mode. Example: If the airlfow demand is 1230 CFM, the LED's will display 12. If the airflow demand is 1275 CFM, the LED's will display 13. Note: The optional usage of a dehumidistat allows the furnace’s circulator blower to operate at a slightly lower speed (85% of desired speed) during a combined thermostat call for cooling and dehumidistat call for dehumidification. This can be done through an independent dehumidistat or through a thermostat’s DEHUM terminal (if available). This lower blower speed enhances dehumidification of the conditioned air as it passes through the AC coil. For proper function, a dehumidistat applied to this furnace must operate on 24 VAC and utilize a switch which opens on humidity rise. 1. All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed. 2. For most jobs, about 400 CFM per ton when cooling is desirable. 3. Do not operate above .5" w.c. ESP in heating mode.

These profiles may be used to enhance cooling performance and increase comfort level. The ramping profiles are selected using DIP switches 5 and 6. Refer to the following figure for switch positions and their corresponding taps. Refer to the bullet points below for a description of each ramping profile. Verify CFM by noting the number displayed on the dual 7-segment LED display. 100% CFM 100% CFM OFF OFF 1 min Profile A: provides only an OFF delay of one (1) minute at 100% of the cooling demand airflow. 100% CFM 100% CFM 50% CFM OFF OFF 1/2 min 1 min Profile B: ramps up to full cooling demand airflow by first stepping up to 50% of the full demand for 30 seconds. The motor then ramps to 100% of the required airflow. A one (1) minute OFF delay at 100% of the cooling airflow is provided. 100% CFM OFF OFF Profile C: ramps up to 85% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile C also has a one (1) minute 100% OFF delay. OFF OFF Profile D: ramps up to 50% of the demad for 1/2 minute, then ramps to 85% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile D has a 1/ 2 minute at 50% airflow OFF delay. 1. All furnaces ship as high speed for cooling.
