DESCRIPTION Reznor®V3 Series Model UDAP gas-fired unit heaters are available in 14 sizes ranging from 30,000 to 400,000
BTUH gas input All sizes are approved for commerciaUndustrial installations.Sizes 30-125 carry an additional
approval for use in attached residential garage/workshop application.Model UDAP heaters are designed for
82-83%thermal efficiency and are approved for installation 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 finish and less
visible hardware.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
ag
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).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 TcoRE2 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 flow, resiliently isolated venter motor, venter wheel with improved housing, resiliently
isolated axial fan and motor assembly,and a high temperature limit control.Sizes 30-125 also include a flame
rollout safety switch.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 efficiency,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.

°Size shown is for gas connection to a single stage gas valve,not supply line size.
e Smaller or larger vent pipe diameters may be allowed;refer to the Venting Installation Manual,Form I-V-PV.If vent diameter is different from vent
connection,reducer/enlargers will be rield.required.
°MOP=2.25 x largest motor FLA+remaining load.Answer is rounded down to the next size of commercially available circuit breaker or fuse.
°All other information in this table is based on a heater equipped with a standard 115 volt open fan motor.
For installations where dirt dust and other air borne contamination is present in the Indoor environment it is
recommended to use separated combustion units(Model UDAS).These models use air from outside the space
for combustion.This will help reduce the build up of contaminates on the burner which would affect the combus-
tion process.Refer to the installation manuals for recommended frequency of maintenance and cleaning.
