It delivers 75,000 BTU\/h of heating output using natural gas. The aluminized steel heat exchanger resists corrosion and thermal fatigue, and is removable for straightforward field serviceability. The 34-inch low-profile cabinet is designed for installations where vertical clearance is limited. Direct spark ignition (DSI) provides reliable, consistent ignition. Licensed HVAC technicians typically handle installation and commissioning of this equipment.\u003c\/p\u003e\u003cp\u003eThis furnace is rated for residential applications and is configured for upflow or horizontal airflow orientation. The integrated control board includes dip switches for simplified system setup, a 7-segment LED display for diagnostics, and a QR code for quick access to product documentation from a mobile device. It is suited for new construction and retrofit installations in homes requiring a medium-capacity single-stage heating system with ECM blower performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE efficiency rating with 75,000 BTU\/h heating capacity\u003c\/li\u003e\n\u003cli\u003eSingle-stage gas valve with natural gas fuel compatibility\u003c\/li\u003e\n\u003cli\u003eConstant torque ECM blower motor for variable airflow efficiency\u003c\/li\u003e\n\u003cli\u003eRemovable aluminized steel heat exchanger for improved serviceability\u003c\/li\u003e\n\u003cli\u003e34-inch low-profile cabinet for space-constrained installations\u003c\/li\u003e\n\u003cli\u003eIntegrated control board with dip switches, 7-segment LED diagnostics, and QR code access\u003c\/li\u003e\n\u003cli\u003eCSA certified for safety and compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation furnace for residential gas heating systems requiring an upflow or horizontal configuration at 75,000 BTU\/h and 80% AFUE.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer instructions.
