General Operation
This GUID furnace is equipped with an electronic ignition
device to light the burners and an induced draft blower to
exhaustcombustionproducts.
Aninterlock switch prevents furnaceoperation ifthe 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 elec-
tronic control module. In the event a furnace component is
notoperating properly, the controlmodule LEDwill flashon
and off in a factory-programmed sequence, depending on
the problem encountered. This light can be viewed through
theobservation window in theblower access door. Referto
the Troubleshooting Chart for further explanation of the
LED codes and Abnormal Operation - Integrated Ignition
Control section in the Service Instructions for an explana-
tion of the possible problem.
Theratedheatingcapacityofthefurnaceshouldbe 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-LoadCalculations” published bytheAirConditioning Con-
tractors of America.
*Obtain from: American National Standards Institute 1430
Broadway New York, NY 10018
LocationConsiderations
• 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
shownin theInstallationand ServiceInstructions.The
length of the rod will depend on the application and
clearance necessary.
• When installed in a residential garage, the furnace
mustbe positioned sotheburnersand ignition source
are located not less than 18 inches (457 mm) above
the floor and protected from physical damage by ve-
hicles.

HighAltitudeDerate
When this furnace is installed at high altitude, the appropri-
ate High Altitude orifice kit must be installed. This is re-
quiredduetothenaturalreductioninthedensity of both the
gas fuel and combustion air as altitude increases. The kit
will provide the proper design certified input rate within the
specifiedaltituderange.

BLOWER PERFORMANCE SPECIFICATIONS
10Rev.1
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 TOBE ADJUSTED TOOBTAIN TEMPERATURERISE WITHIN THERANGE SPECIFIEDON
THERATINGPLATE.
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.
6 The dashed (---) areas indicate a temperature rise not recommended for this model.
7. The above chart is for U.S. furnaces installed at 0-2000 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.
