PRODUCT DESIGN

General Operation

furnaces are equipped with an electronic ignition de-

GME8
vice 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.

NOTE: Gas furnaces with induced draft blowers draw
products of combustion through a heat exchanger allowing,
in some instances, common venting with natural draft
appliances (i.e. water heaters). All installations must be
vented in accordance with National Fuel Gas Code NFPA
54/ANSI Z223.1 - latest edition. In Canada, the furnaces
must be vented in accordance with the National Standard of
Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest
editions and amendments.

NOTE: The vertical height of the Category I venting system
must be at least as great as the horizontal length of the
venting system.

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.

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.

* These furnaces are manufactured for natural gas operation. Optional Kits are available for conversion to propane gas operation.
* 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.

* 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.

1. CFM in chart is without filters(s). Filters do not ship with this furnace, but must be provided by the installer.

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.
