UDZ UNIT HEATER - SEPARATED COMBUSTION, LOW STATIC AXIAL } FAN COMMERCIAL/INDUSTRIAL UNIT HEATERS 82 - 83% THERMAL EFFICIENCY Reznor® Model UDZ gas-fired unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH 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 2 or 4 suspension points. Or, an optional hanger kit for sizes 30-125 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 a "G" terminal 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 offer a sleek design sure to complement any space. The UDZ features a two-tone black and white powder coated, scratch-resistant paint scheme with a single red louver. Each unit has clean rounded corners and edges with no visible screws or fasteners, and the bottom is embossed with the Reznor logo. Model UDZ unit heaters provide the same superior performance customers have relied on for more than 100 years along with added features that make servicing the unit easier, installation safer and improve monitoring capabilities.
