The Vacuum System Gas Tube Heaters U-Tube is a natural gas infrared heater designed to offer significant fuel savings of up to 70%. This heater configuration is ideal for high heat loss areas, such as loading docks, as it features a vacuum system that pulls products of combustion through a combustion chamber, enhancing radiant efficiency and safety. It includes reliable direct spark ignition, 100% gas shut-off safety control, and supports up to 50 feet of ducting in fresh air and 75 feet of sidewall venting capability. The vacuum system incorporates a totally enclosed combustion chamber, complemented by a heavy-duty draft inducer assembly with a permanently lubricated, totally enclosed ball-bearing motor for maintenance-free operation. Highly efficient aluminum reflectors are included, along with a diaphragm air switch, heavy-duty cast iron burner, and burner inspection sight glass. The diagnostic monitoring light system enhances operational oversight. The heater requires a 120V supply and is CSA certified. This product comes with a 5-year limited warranty on tubes and a 1-year limited warranty on the unit. It is made in the USA, and installation and service must be performed by a licensed contractor in accordance with local codes.
