FEATURES and BENEFITS
FG7T (A and K Series)
, Smartlite
Two Stage, Fixed Speed,
High Efficiency Upflow/Horizontal
and Downflow Gas Furnaces
• i SEER: Energy efficient brushless DC (ECM) motor
gives up to 1 SEER point efficiency gain in cooling.
• 100% fired and tested: All units and each component
are tested on the manufacturing line.
• Best packaging in the industry: Unique corner post
design assures product will arrive to the homeowner dent
free.
®
• LowBoyHeight:Easytoapplyinlowceilingapplications,
works well with taller high SEER coils, easier to handle
and install.
Induced Draft - 80 + AFUE
Input 60,000 - 140,000 Btuh
• Tubular primary heat exchanger: Heavy gauge
aluminized steel heat exchanger assures a long life.
• 30 second blower delay at start-up: Assures a warm
duct temperature at furnace start-up. Adjustable blower
off settings (60, 90, 120 and 180 seconds).
• 30 second post purge: Increases life of heat
exchanger.
The high efficiency gas furnace may be installed free
standing in a utility room, basement, or enclosed in an
alcove or closet. The rounded corner jacket provides a
pleasing“appliance appearance.”Design certified by CSA
for application in Canada and the United States.
• Hot surface igniter: Innovative application of a silicon
®
nitride igniter. Utilizes proven Smartlite technology.
• Color coded wire harness: Designed to fit the
components, all with quick-connect fittings for ease of
service and replacement.
• Highstaticblowers:Allmodelsequippedwithhighstatic
blowers.
• 90 second cooling cycle blower-off delay (TDR):
Increases cooling performance when matched with a
NORDYNE coil.
• Flexible category I venting system: May be vented
with dedicated venting system or common vented with
other category one appliances.
• Variable speed blower kit: Upgradable to full variable
speed with kit.
• LPconvertible:Simpleburnerorificeandregulatorspring
change for ease of convertibility.
• Diagnostic lights for easy troubleshooting without
counting flashes: Dedicated light for flame signal
strength and 2 lights in combination to indicate all other
faultcodeswitheasytorecognizestateswithoutcounting
flashes.
• Integrated control board: Incorporates connections for
electronic air cleaner, humidifier and twinning.
• Two piece door design:Enhances furnace appearance
and uses captured screws to prevent loosing door
screws.

Notes:
1. Motor Switch Settings are for heating speeds using HEAT switches 1, 2, 3, & 4 and cooling speeds using COOL switches 5, 6, 7, & 8.
2. Two openings are recommended for airflows above 1600 CFM if the filter(s) is (are) adjacent to the furnace.
3. Data is shown without filter.
4. Temperature rises in the table are approximate. Actual temperature rises may vary.
5. Temperature rises that are shaded in grey are for reference only. These conditions are not recommended.

Notes:
1. Motor Switch Settings are for heating speeds using HEAT switches 1, 2, 3, & 4 and cooling speeds using COOL switches 5, 6, 7, & 8.
2. Two openings are recommended for airflows above 1600 CFM if the filter(s) is (are) adjacent to the furnace.
3. Data is shown without filter.
4. Temperature rises in the table are approximate. Actual temperature rises may vary.
5. Temperature rises that are shaded in grey are for reference only. These conditions are not recommended.
