PRODUCT DESIGN
General Operation
The AMV9 and ACV9 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.
This furnace is also equipped with a self-diagnosing electronic control module. In the event a furnace component is
not operating properly, the control module LED will flash on
and off in a factory-programmed sequence, depending on
the problem encountered. This light can 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 Ignition 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.

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:
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.

Note: In all cases accessibility clearance shall take precedence over clearances from the enclosure where accessibility clearances are greater. All dimensions are given in
inches.
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.
•
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.

Coil Matches:
A large array of Amana® brand coils are available for use with the new ACV9 furnaces, in either counterflow or horizontal
applications & with AMV9 furnaces, in either upflow or horizontal applications. These coils are available in both cased
and uncased models, with or without a TXV expansion device. These new 92%+ and 95%+ furnaces match up with the
existing Amana® brand coils as shown in the chart below.

*1213406 is the recommended model for the AMV9 & ACV9 furnaces when used with a heat pump in a fossil fuel
application. It is NOT for use with either the AMV9 or ACV9 as a sole heating source. 1213406 thermstats are 24V
powered with battery backup.
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
This furnace has provisions for the installation of return air filters at the side and/or bottom return. The furnace will
accommodate the following filter sizes depending on cabinet size:

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.

2. All furnaces shipped with heating speed set at "B" and cooling speed set at "D". Installer should adjust blower speed as needed.
The first task is to determine the proper aiflow for the cooling system.
3. For most cooling applications, about 400 CFM per ton is desirable.
4. The chart is for information only. For satisfactory operation, external static pressure not to exceed value shown on rating plate.
5. Do not operate above 0.5" w.c. ESP in heating mode. Operating between 0.5" w.c. and 0.8" w.c. is tabulated for cooling purposes only.

as needed. The first task is to determine the proper aiflow for the cooling system.
3. For most cooling applications, about 400 CFM per ton is desirable.
