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 Reznor Shop Heater, UDAP-30 V3 Gas Fired Unit Heater 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.
