V3 Series Model UDBP gas-red unit heaters are available in 14 sizes ranging from 30,000 to 400,000
BTUH gas input. Model UDBP heaters are designed for 82-83% thermal efciency and are approved for com-
mercial/industrial installations in the United States and Canada by the Canadian Standards Association (CSA).
Reznor V3 Series unit heaters have a refreshing new appearance with a glossy white cabinet nish and less
visible hardware. Each size cabinet is easily suspended from four 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 blower only operation
(without adding relays). All units have a factory installed gas line nipple to the exterior of the cabinet for easy
gas service connection.
The preeminent new internal feature is the T
core
2
heat exchanger and single burner combustion system. Other
standard features include a single-stage gas valve, multi-try direct spark ignition with timed lockout, pressure
switch to verify vent ow, resiliently isolated venter motor, venter wheel with improved housing, and a high
temperature limit control. Sizes 30-125 are equipped with a centrifugal blower and direct drive motor with multi-
speed taps. Sizes 30 and 45 are capable of handling up to .5” w.c. of external static pressure; Sizes 60-125 will
handle up to .75” w.c. of external static pressure. Sizes 150-400 are equipped with a centrifugal blower with an
adjustable belt drive and motor. All units are designed for use with optional 30° and 60° downturn nozzles with
horizontal and vertical louvers. Operation is controlled through an integrated circuit board. The circuit board
monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.
The V3 Series unit heaters are designed to provide all the features you expect in a Reznor heater plus im-
proved efciency, easier installation, and a new look ~ both inside and out. Look for the unique white unit
with no visible front and bottom hardware, deep red louvers, black side handle, and angled corner to know you
have a genuine Reznor heater.
