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 CTK01AA 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, GMVC95, AMVC95 and ACVC9 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. These LED's may be viewed
through the observation window in the blower access door.
Refer to the Troubleshooting Chart for further explanation of
the LED codes and Abnormal Operation - Integrated Igni-
tion Control section in the Service Instructions for an expla­nation of the possible problem.

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 above 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.

Single Stage Thermostat

A single-stage thermostat with only one heating stage may
be used to control this furnace. The application of a single­stage thermostat does not offer “true” thermostat-driven two­stage operation, but provides a timed transition from low to
high fire. The furnace will run on low stage for a fixed period

of time before stepping up to high stage to satisfy the
thermostat’s call for heat. The delay period prior to stepping
up can be set at either a fixed 5 minute time delay or a load
based variable time between 1 and 12 minutes (AUTO mode).
If the AUTOmode is selected, the control averages the cycle
times of the previous three cycles and uses the average to
determine the time to transition from low stage to high stage.

To use a single-stage thermostat, turn off power to the fur­nace, move the thermostat selection DIP switch to the OFF
position. Set the desired transition time by setting the tran­sition delay DIP switch to the desired ON/OFF position. Turn
power back on. Refer to the following figure.

Filters:

Filters are required with this furnace and must be provided by the installer. The filters used must comply with UL900 or
CAN/ULCS111 standards. Installing this furnace without filters will void the unit warranty

Upflow Filters

Return air filters may be installated at the furnace side and/or bottom return openings. The furnace bottom return opening
and side openings will accommodate the following filter sizes depending on cabinet size:

Note: Continuous fan speed will be 30% of the
furnace's maximum airflow capability. If the fur­nace maximum CFM capaibility is 1760 CFM, the
continuous fan speed will be 0.30 X 1760 CFM =
530 CFM.

Example: If the furnace maximum CFM capaibility
is 1760 CFM, the continuous fan speed will be

0.30 X 1760 CFM = 530 CFM.

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.

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.
