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 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

LED codes and

Control

section in the Service Instructions for an explana-

Abnormal Operation - Integrated Ignition

for further explanation of the

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 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.

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 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.

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.

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.

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.
