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

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.
