Reznor Gas-Fired Unit Heater, Power-Vented Low-Static Axial Fan Convertible, 83% Efficient, 45000 BTU

The Reznor (REZ-UDXC-045) Gas-Fired Unit Heater delivers 45,000 BTU input capacity with approximately 82-83% thermal efficiency. It features the TCORE2® titanium-stabilized aluminized steel heat exchanger for enhanced durability, a power-vented low-static axial fan for quiet and efficient airflow, and supports field conversion to separated-combustion (fresh-air intake) to suit dusty or challenging environments. For installation, technicians will appreciate the 115 V single-phase power supply, external gas-pipe connection for streamlined servicing, and a sealed control compartment with LED status and fault-code display for quick diagnostics. The compact cabinet supports ceiling-suspended or wall-mounted configurations via built-in 2- or 4-point suspension tabs, and the modern two-tone powder-coated finish ensures it fits well in both commercial and industrial settings. Technicians must ensure proper venting diameter, maintain manufacturer-specified clearances, and follow suspension guidelines to guarantee code-compliant performance.
