Gibson KG7T Two Stage Fixed Speed High-Efficiency Upflow Horizontal and Downflow Gas Furnaces

TECHNICAL SPECIFICATIONS

KG7T (A and K Series) Two-Stage, Fixed Speed

• High Efficiency Upflow/Horizontal and Downflow Gas Furnaces
• Induced Draft – 80+ AFUE
• Input 60,000 – 140,000 Btuh
• The high-efficiency gas furnace may be installed free-standing in a utility room, or basement, or enclosed in an alcove or closet.
• The rounded corner jacket provides a pleasing “appliance appearance.” Design certified by CSA for application in the United States and Canada.

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 the product will arrive at 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 the life of the heat exchanger.
• Hot surface ignitor: Innovative application of an appliance-type ignitor with a 20-year history of reliability. Utilizes proven Smartlite® 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 are 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: This may be vented with the dedicated venting system or commonly vented with other category one appliances.
• Variable speed blower kit: Upgradable to full variable speed with the 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.
• Integrated control board: Incorporates connections for electronic air cleaner and humidifier.
• Two-piece door design: Enhances furnace appearance and uses captured screws to prevent losing door screws.
• Energy Efficient Brushless DC (ECM) Motor: Gives up to 1 SEER point efficiency gain in cooling.
• Furnace Air Leakage: These furnaces comply with the Energy Star cabinet air leakage requirement of less than or equal to 2%. Keep the conditioned air flowing to where it’s needed.

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 required for airflows above 1600 CFM if the filter(s) is (are) adjacent to the furnace.
3. Data is shown without the filter.
4. Temperature rises in the table are approximate. Actual temperature rises may vary.
5. Temperature rises that are shaded in grey are not recommended.
