UBX Series
Reznor® Model UBX gas-fired unit heaters are available in 14 sizes
ranging from 30,000 to 400,000 BTUH gas input. Model UBX heaters
are approved for installation in the United States and Canada by ETL.
Each size cabinet is easily suspended from 4 suspension points. 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 UBX 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 UBX 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.
