General Operation
The GME95 furnaces are equipped with an electronic igni-
tion 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 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 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 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.
Notes:
1. Installer must supply one or two PVC pipes: one for com-
bustion 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.
GME95 furnaces are approved
for installations up to 7,000 ft. only.
