KG7T Condensing Upflow/Horizontal And Downflow Gas Furnace

The high efficiency upflow gas furnace may be installed free standing in a utility room, basement, or enclosed in an alcove or closet. Upflow/Horizontal units come ready for upflow or horizontal application. The extended flush 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: www.CleanAirFurnaceRebate.com.

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.
• 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 an appliance type igniter with a 20 year history of reliability. Utilizes proven Smartlite® technology.

• 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 and stainless steel secondary heat exchanger assures a long life.
• 90 second fixed cooling cycle blower-off delay (TDR): Increases cooling performance when matched with a Nortek Global HVAC coil.
• Variable speed blower kit: Upgradable to full variable speed with kit.
• 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.
• Incorporates integrated control board: With connections for electronic air cleaner and humidifier.
• Two piece door design: Enhances furnace appearance and uses captured screws to prevent losing door screws.
• Sealed vestibule: Reduces burner and inducer sound levels.
• Energy efficient brushless DC (ECM) motor: Gives up to 1 SEER point efficiency gain in cooling.
• 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.

Note:
All models are 115V, 60 Hz. Gas Connections are 1/2″ N.P.T. AFUE = Annual Fuel Utilization Efficiency (a) Ratings to 2,000 ft. Over 2,000 ft. reduce 4% for each 1,000 ft. above sea level.

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 1,600 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. Cells shaded in gray indicate a temperature rise outside of the recommended range.
6. When in low stage, the circulating airflow is 70% of the tables high value (2-stage furnaces only).

*NOTES:

1. Subtract 2.5 ft. for each additional 2 inch long radius elbow, 5 ft. for each additional 2 inch short radius elbow, 3.5 ft. for each additional 3 inch long radius elbow, and 7 ft. for each additional 3 inch short radius elbow. Subtract 5ft for each 2” tee and 8ft for each 3” tee.
2. Two 45 degree elbows are equivalent to one 90 degree elbow.
3. This table applies for elevations from sea level to 2,000 ft. For higher elevations, decrease pipe lengths by 8% per 1,000 ft of altitude.
