Abstract: An apparatus for cleaning components of a conventional oil tank heater includes a pair of containment drums, a drop cloth selectively mountable over the burner end or exhaust end of the heater tube for deflecting debris into the associated drum, and a high-pressure water hose having a nozzle with rearwardly-directed discharge ports. With one drum mounted over each of the heater tube's burner and exhaust ends, and with the drop cloth mounted over a selected one of the heater tube ends, the nozzle may be inserted under the drop cloth and into other end of the heater tube and manipulated as required within the heater components. High-pressure wash water streams exiting the nozzle ports are thus directed against the inner surfaces of the stack or other heater components traversed by the nozzle. The high-pressure water streams dislodge accumulated contaminants, which are deflected by the drop cloth into one of the collection drums and conveyed therefrom to a collection vessel.

Abstract: A method for cleaning an exhaust stack tube of an oil tank heater comprises the steps of securing collection drums at open ends of a heater tube using attaching straps; securing a drop cloth over an exhaust end of the heater tube with an attaching strap; interconnecting the collection drums to one of a vacuum apparatus and a receptacle container; attaching a nozzle to an end of a high pressure hose; inserting the nozzle under the drop cloth and into an exhaust end of the heater tube; forcing wash water under pressure through the nozzle; guiding the nozzle to the top of the exhaust stack; pulling the nozzle back a few feet and, again, guiding the nozzle upward while rotating the nozzle; and repeating this process until the nozzle reaches the bottom of the exhaust stack.
