REZNOR® model UDZ gas fired unit heaters are available in 14 sizes ranging from 30000 to 400000 Btu/hr gas input. Model UDZ heaters are approved for installation in the United States and Canada by ETL. Each size cabinet is easily suspended from either two or four suspension points. Or, an optional hanger kit for Sizes 30 to 125 allows for ceiling-mounting. The low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of terminal G to the strip, along with the new design of the circuit board, allows for fan only operation (without adding relays). REZNOR® model UDZ unit heaters feature a two-tone black and white powder-coated, scratch-resistant paint scheme. Each unit has clean rounded corners and edges with no visible screws or fasteners. Model UDZ unit heaters provide the same superior performance customers have relied on for more than 100 years along with added features that improve monitoring capabilities and make servicing the unit easier and installation safer.
