Reznor® series model UDBS gas-fired separated combustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input. Model UDBS heaters are designed for 82-83% thermal efficiency and are approved for commercial/industrial installations 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 four suspensionpoints. 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 blower 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 100% lockout, pressure switch to verify vent flow, resiliently isolated venter motor, venter wheel with improved housing, a high temperature limit control, interlock door switch, and a built-in disconnect switch. Sizes 30-125 are equipped with a centrifugal blower and direct drive motor with multispeed taps. Sizes 30 and 45 are capable of handling up to .5" w.c. of external static pressure; sizes 60-125 will handle up to .75" w.c. of external static pressure. Sizes 150-400 are equipped with a centrifugal blower with an adjustable belt drive and motor. All units are designed for use with optional 30° and 60° downturn nozzles with horizontal and vertical louvers. 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 1ST 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 UDBS 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. 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.
