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)

(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.

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.

1.
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.

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.

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.
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.

BLOWER PERFORMANCE SPECIFICATIONS
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.
