Reznor
®
V3 Series Model UEAS gas-red, high efciency, separated combustion unit heaters are available in 4
sizes ranging from 131,000 to 305,000 BTUH gas input. Heaters are designed for up to 93% thermal efciency
and are approved for installation in the United States and Canada by ETL.
Reznor V3 Series unit heaters have a refreshing appearance with a glossy white cabinet nish and less visible
hardware. 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 low voltage 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 MacroChannel
®
secondary heat exchanger has a 1/2” PVC pipe for attaching a
coupling for ease of installation and cleaning of the required condensate drain. A 4” PVC cleanout cap that is
drilled and tapped for a 1/2” NPT tting is furnished with the heater for attaching the vent condensate drain.
The preeminent new internal feature is the T
core
3 ®
high efciency heat exchanger and single burner combus-
tion system. Other standard features include a single-stage gas valve, multi-try direct spark ignition with timed
lockout, pressure switch to verify vent ow, venter motor, aluminum venter wheel with housing, resiliently
isolated axial fan and motor assembly, a high temperature limit control, interlock door switch, and a built-in
disconnect 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 1
ST
everseparatedcombustion system in the commercial/industrial heating industry wasintroduced
on a Reznor heater in the 1960s, and that proven technology is continued in this new separated combustion
product. Model UEAS separated combustion units require installation of a specially designed combustion air/
vent system including the unique concentric adapter box that allows for only one building penetration for both
the vent and combustion air.
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.
