Literature Library G8SA Gas Furnace

The 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 furnace series is approved and certified by the SCAQMD and the SJVAPC Districts in the state of California with NOx levels below 14 ng/J when operating on natural gas.

FEATURES and BENEFITS

• Ultra-low emissions: 65% less NOx than standard furnaces. 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’s 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 igniter: Innovative application of a silicon nitride igniter.
• Colour-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.
• 60-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 common vent with other category one appliances.
• High-efficiency blower kits: Maximize efficiencies and provide better temperature control, humidity control and air distribution.
• Multi-speed direct drive blower: Energy-efficient, brushless DC (ECM). Designed to give a wide range of cooling capacities. Switches on PCB, provide ultra-easy motor speed selection.
• 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. Ergonomically located for ease of service.
• Two-piece door design: Enhances furnace appearance and uses captured screws to prevent losing door screws.
• 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.
