Easy Installation: Reznor UDX heaters are designed for hassle-free installation. They can be securely mounted using 2 or 4 suspension points or an optional hanger kit for ceiling mounting. The thermostat setup is streamlined with a low-voltage terminal strip on the exterior of the cabinet, simplifying control wiring without the need to remove panels. Additionally, the factory-installed gas line input is conveniently positioned on the backside of the unit heater, facilitating straightforward gas connections.

Advanced Features: Reznor has enhanced the UDX heaters for improved performance and user experience. Key features include Reznor’s patented TCore² titanium-stabilized aluminized steel heat exchanger, a "G" terminal strip, and a newly designed circuit board that allows for fan-only operation without adding relays. The redesigned cabinet boasts a modern look with no visible front or bottom hardware, external status-indicating LED lights, a hinged door for easy access to the control panel, and a removable front face. The distinctive white and black powder-coated finish, bright red Reznor logo, and angled corners ensure you have a genuine Reznor unit.
