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.
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.

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.
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.
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.
*Obtain from: American National Standards Institute 1430
Broadway New York, NY 10018
Location Considerations
• 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.
• 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.
Notes:
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.
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.
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.

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.

These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
2.
For elevations above 2000 ft. the rating should be reduced by 4% for each 1000 ft. above sea level. The furnace must not be derated, orifice changes should only be made if necessary for altitude.
3.
The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufactures method in accordance with the
"A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CONDITIONING CONTRACTORS OF AMERICA. The total heat loss calculated should be equal to or less than the heating capacity. Output based on D.O.E. test procedures, steady state efficiency times output.

Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps.

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. Operating CFM between .5" and .8" w.c. is tabulated for cooling purposes only.
4.
Continuous fan speeds of 25%, 50%, 75% of maximum cooling airflow are available when using a communicating thermostat and 25%, 50%, 75%, 100% of maximum cooling airflow are available in legacy mode by setting dip switches

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. Operating CFM between .5" and .8" w.c. is tabulated for cooling purposes only.
4.
Continuous fan speeds of 25%, 50%, 75% of maximum cooling airflow are available when using a communicating thermostat and 25%, 50%, 75%, 100% of maximum cooling airflow are available in legacy mode by setting dip switches

Note:
There are dual 7-segment LED's adjacent to the selection dipswitches. 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.

Ramping Profile
Note:
The multi-speed circulator blower also offers several custom ON/OFF ramping profiles. 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.
