The Reznor’s Models VPS & VPT Gas-Fired Tubular Radiant, Low Intensity Heater for Indoor Commercial-Industrial Use
The Reznor VP series of tubular radiant heaters are available in BTUH inputs ranging from 60,000 to 200,000
and in system lengths from 20 to 80 feet (see the following pages for BTUH/system length combinations). Heaters are available for use with natural gas or optional propane gas. Tubular radiant heaters are engineered to provide quiet, reliable, energy-efficient, comfort level heating for both spot and space applications.
These radiant heaters are ready for use for elevations up to 2,000 ft. (610 M) above sea level. For installations in the u.S. above 2,000 ft., a high elevation adapter kit is available. units can also be installed above 2,000 ft. elevation in Canada – see the installation manual for details.
The VP series is designed with a burner/control box housing a power burner that fires into a combustion chamber and heat exchanger tubes, 20 to 80 feet in length. The burner is equipped with a positive pressure blower for supplying combustion air and a multi-try direct spark ignition with soft lockout. Controls include a single-stage (Model VPS) or two-stage (Model VPT) gas valve and a pressure switch to verify combustion air flow.
The Calcoat™ and rolled steel tubes are in 10-foot sections with each section having an aluminized steel reflector. Optional stainless steel (300 series grade) tubes and (400 series grade) reflectors are also available. Additional “l” and “u” shaped tubes as well as 5 ft. (1.5 M) tubes are available in rolled or stainless steel. These accessories allow the radiant tube system 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.
Combustion air can either come from the heated space or be piped from the outside. An outside combustion air inlet kit should be used (1) if the building atmosphere has negative pressure; (2) if the building atmosphere is mildly dirty or dusty; (3) if the heater is being installed in a tightly closed room that does not provide required air for combustion. Warranty will be void for heaters installed in mildly dirty or dusty environment without outside combustion air inlet
