Reznor® V3 series
model UDAS gas-fired separated combustion unit heaters are available in
14 sizes ranging from 30,000 to 400,000 BTUH gas input. Sizes 30-125
are approved for residential application. All sizes are approved for
commercial/industrial installations. Model UDAS 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, the unique REZNOR mitered
corner, and less visible hardware. Each size cabinet is easily
suspended from either 2 or 4 suspension points, or an optional hanger
kit for all sizes 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). 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-CORE2 ® heat
exchanger and single burner combustion system. Other standard features
include a single-stage gas valve, multi-try direct spark ignition with
100% 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 first ever separated combustion system in the
commercial/industrial heating industry was introduced on a Reznor heater
in the 1960’s, and that proven technology is continued in this new
separated combustion product. Model UDAS 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 new V3 Series unit heaters are designed to provide all the
features you expect in a Reznor heater plus improved efficiency, easier
installation and a new look ~ both inside and out.
Note: Selection of either a horizontal or vertical combustion
air/vent kit is required.
