Reznor® V3 series model UDAP gas-fired unit heater

Reznor V3 Series Model UDAP gas heater

Reznor® V3 series model UDAP gas-fired 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 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, 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 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. 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 unit by Thomas & Betts.
