WARNING

Serious property damage, personal injury, reduced unit
performance and/or hazardous conditions may result
from the use of such non-approved devices.

The United States Environmental Protection Agency (“EPA”) has issued various regulations re­garding the introduction and disposal of refrigerants introduced into this unit. 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.

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.

Note: The typical sea level negative pressure data represents the minimum pressures expected. S horter length of flue pipe or single pipe systems compared to
dual pipe syste ms should show higher (greater ne gative) press ures.

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.

4. 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

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.

4. Continuous fan speeds of 25%, 50%, 75% of maximum cooling airflow are available when using a communicating thermostat and 25%, 50%, 75%, 100%

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.
