PRODUCT DESIGN

General Operation
This GUID furnace is 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 elec-
tronic 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 explana-
tion 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 Con-
tractors of America.

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 ve-
hicles.

High Altitude Derate
When this furnace is installed at high altitude, the appropri-
ate High Altitude orifice kit must be installed. This is re-
quired 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.
