Compliance and Restrictions



Dayton tube heaters are gas-fired infrared heaters designed to provide comfort heat. They consist of three (3) main components: a burner control box, radiant tube, and reflector assembly. The heaters are typically suspended from the ceiling by chains and controlled by a thermostat. They can be installed either vented or unvented, and may use outside air for combustion if necessary. The radiant tube may be installed in different configurations depending on the heating requirements. These heaters use infrared energy to heat spaces. When heat is required, the burner control box ignites a gas/air mixture and pushes the hot gases into the radiant tube. As the gases pass through the assembly, the tubing is heated and emits infrared, which is then directed toward the floor by reflectors. This is known as primary infrared and is absorbed by the floor, objects and people in the space, raising their temperatures. They in turn re-radiate this heat, known as secondary infrared, to create a comfort zone at the floor level. This is how Dayton tube heaters can heat large spaces without having to provide primary infrared for every square foot of area. However, if the goal is to spot heat a small area within a large space, only the primary infrared makes this possible. Dayton tube heaters are design certified for use in industrial and commercial buildings, such as warehouses, manufacturing plants, aircraft hangars and vehicle maintenance shops. They are not certified for residential use or where flammable gases or vapors are generally present, such as spray booths.
