TECHNICAL SPECIFICATIONS
FG7S (A and K Series)
High Efficiency Upflow/Horizontal and
Downflow Gas Furnaces
Induced Draft – 80+ AFUE
Input 45,000 – 126,000 Btuh
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.
This furnace series is approved and certified by the SCAQM and the SJVAPC
Districts in the state of California under each Districts’ Mitigation Fee Plan
for shipment into and sales in both districts.
For California installations in SCAQMD only: This furnace does not meet the
SCAQMD Rule 1111 NOx emission limit (14 ng/J), and thus is subject to a
mitigation fee of up to $450. This furnace is not eligible for the Clean Air
Furnace Rebate Program:

FEATURES and BENEFITS
- 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.
- Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils, easier to handle and install.
- 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.
- Hot surface igniter: Innovative application of a silicon nitride igniter. Utilizes proven Smartlife ® technology.
- Color coded wire harness: Designed to fit the components, all with quick-connect fittings for ease of service and replacement.
- High static blowers: All models equipped with high static blowers.
- 90 second cooling cycle blower-off delay (TDR): increases cooling performance when matched with a Nortek Global HVAC coil.
- Flexible category I venting system: May be vented with dedicated venting system or common vented with other category one appliances.
- High efficiency blower kits: Maximize efficiencies. On select units, a SEER improvement of up to 1 point is realized.
- Multi-speed direct drive blower: Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra easy motor speed selection.
- LP convertible: Simple burner orifice and regulator spring 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 fault codes with easy to recognize states without counting flashes.
- Integrated control board: Incorporates connections for electronic air cleaner and humidifier.
- Two piece door design: Enhances furnace appearance and uses captured screws to prevent loosing door screws.
- Blower Compartment: Insulated for ultra quiet operation.
- Furnace Air Leakage: These furnaces comply with Energy Star cabinet air leakage requirement of less than or equal to 2%. Keep the conditioned air flowing to where it’s needed.
