Reznor® Model VR tubular radiant heaters

Reznor Model VR Tubular Radiant Heater

Model VR tubular radiant heaters are available in BTUH inputs of 50,000 to 200,000 and in tube lengths from 20 to 70 feet (see the Technical Data table for BTUH/length combinations).  All sizes are available for use with natural gas or optional propane gas.  Model VR heaters provide full input rate heating capacity to 2,000 feet elevation.  Tubular radiant heaters are engineered to provide quiet, reliable, energy-efficient, comfort level heating for both spot and space applications.  Model VR is designed with a burner/control box housing a power burner that fires into a 4″ diameter tube, 20 to 70 feet in length.  The burner is equipped with a blower for supplying combustion air and a multi-try direct ignition with 100% lockout.  Controls include a single-stage gas valve and a pressure switch to verify combustion air flow.

The tubes are in 10-foot sections with each section having a polished reflector.  The tube attached to the burner is the combustion chamber, all other sections are highly emissive heat exchanger tubes.  The standard configuration is straight, but optional “L” shaped, “U” shaped and 5-foot straight heat exchanger tubes are available to change the configuration to adapt to various applications.  A tubular system including an optional “U” tube provides the best balance of radiant emission over the length of any system.  For maximum efficiency, the exhaust end of all systems is equipped with an aluminized steel turbulator strip.

Combustion air can either come from the heated space or be piped from the outside.  Outside combustion air should be supplied (1) if the building atmosphere has negative pressure; (2) if the building atmosphere is dirty or dusty; (3) if the building atmosphere contains substances that will cause toxic gas when combined with flame or flue products; or (4) if the heater is being installed in a tightly closed room that does not provide required air for combustion.

Venting may be either vertical or horizontal.  Dual venting of two units is permissible when using a Reznor� optional dual vent kit.  Model VR tubular heater systems are shipped in modular packages requiring field assembly and installation.  Standard features, such as wire form hangers for chain suspension, compression coupling tube connections, and terminal board thermostat connection are designed to facilitate installation.

These heaters are approved for use in the United States and Canada by the Canadian Standards Association (CSA).  Reznor� provides a five-year limited warranty on the burner and a ten-year limited warranty on all tubes.
