PRODUCT IDENTIFICATION
The model and manufacturing number are used for positive identification of component parts used in manufacturing.
When engineering and manufacturing changes take place where interchangeability of components are affected, the
manufacturing number will change.
It is very important to use the model and manufacturing numbers at all times when requesting service or parts information.

PRODUCT DESIGN
General Operation
This GUIS/GCIS furnace is equipped with an electronic
ignition device to light the burners and an induced draft
blower to exhaust combustion products.
Location Considerations
•
The furnace should be as centralized as is practical
with respect to the air distribution system.
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.
•
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 3/8” 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.

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.
Note: For propane gas installations, the LPTK09 conversion kit has the required orifices
for installations up to 7,000 feet. For Propane gas installations between 3,001 and 7,000
feet, the HATS kits listed above are required for the pressure switch change.

Coil Matches:
A large array of Amana coils are available for use with the GUIS and GCIS furnaces, in either upflow, counterflow, or
horizontal applications. These coils are available in both cased and uncased models, with or without a TXV expansion
device. These 80% furnaces match up with the existing Amana coils as shown in the chart below.

1. These furnaces are manufactured for natural gas operation. Optional kits are available for conversion to propane
gas operation.
2. For elevations above 2000 feet the rating should be reduced by 4% for each 1000 feet 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 manufacturers
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. CFM in chart is without filters(s). Filters do not ship with this furnace, but must be provided by the installer. If the
furnace requires two return filters, this chart assumes both filters are installed.
2. Blower speeds for each firing rate are set independant of each other.
3. All furnaces ship as high speed cooling. Installer must adjust blower cooling speed as needed.
4. For most jobs, about 400 CFM per ton when cooling is desirable.
5. INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON
THE RATING PLATE.
6. The chart is for information only. For satisfactory operation, external static pressure must not exceed value shown
on rating plate. The shaded area indicates ranges in excess of maximum external static pressure allowed when
heating.
7
The dashed (---) areas indicate a temperature rise not recommended for this model.
8. The above chart is for U.S. furnaces installed at 0-2000 feet. At higher altitudes, a properly derated unit will have
approximately the same temperature rise at a particular CFM, while the ESP at that CFM will be lower.

IMPORTANT:
READ BEFORE OPERATING OR SERVICING THIS UNIT
1. SET HEAT ANTICIPATOR ON ROOM THERMOSTAT AT 0.7 AMPS.
2. AMANA SPECIFIED REPLACEMENT PARTS MUST BE USED WHEN SERVICING.
3. IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE FURNACE MUST BE
REPLACED, IT MUST BE REPLACED WITH WIRING MATERIAL HAVING A TEMPERATURE RATING OF AT LEAST
105°C. USE COPPER CONDUCTORS ONLY.
4. UNUSED BLOWER MOTOR LEADS MUST BE PLACED ON "PARK" TERMINALS OF CONTROL OR TAPED.
5 IF HEATING AND COOLING BLOWER SPEEDS ARE NOT THE SAME DISCARD JUMPER BEFORE CONNECTING
BLOWER LEADS. USED ONLY IF HIGH STAGE HEAT AND COOLING USE THE SAME SPEED.
6 IF HIGH STAGE HEAT AND LOW STAGE HEAT SPEEDS ARE NOT THE SAME DISCARD
JUMPER BEFORE CONNECTING BLOWER LEADS. USE ONLY
IF HIGH STAGE HEAT AND LOW STAGE HEAT USE THE SAME SPEED.
7 DIAGNOSTIC LIGHT: CONTINUOUS ON = INTERNAL LOCKOUT -REPLACE CONTROL; 1 FLASH = EXTERNAL LOCKOUT - CHECK FURNACE;
2 FLASHES - PRESSURE SWITCH STUCK CLOSED; 3 FLASHES - PRESSURE SWITCH STUCK OPEN; 4 FLASHES - OPEN THERMAL
PROTECTION DEVICE; CONTINUOUS FLASH - FLAME SENSED - NO CALL FOR HEAT STAT RECOVERY (1/4 SEC. ON, 1/4 SEC. OFF).
8 PLUG CONNECT FOR FURNACE TWINNING.
TO AVOID POSSIBLE ELECTRICAL SHOCK, PERSONAL INJURY,
OR DEATH, DISCONNECT THE POWER BEFORE SERVICING.
