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
The GKS9 furnaces are equipped with an electronic ignition
device used 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 door 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.
*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 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.
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 high altitude natural or 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 90º Elbows, one close nipple, straight pipe.
Right -- Straight pipe to reach gas valve.

Note: In all cases accessibility clearance shall take prece-
dence 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. These furnaces are manufactured for natural gas operation. Optional kits are available for conversion to propane 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 or 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.
Unit specifications are subject to change without notice.

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. All furnaces ship as high speed cooling. Installer must adjust blower cooling speed as needed.
3. For most jobs, about 400 CFM per ton when cooling is desirable.
4. INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
5. 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. The data for 0.6" w.c. to 0.8" w.c.
is shown for air conditioning purposes only.
6 The dashed (---) areas indicate a temperature rise not recommended for this model.
7. The above chart is for U.S. furnaces installed at 0-4000 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.
