Abstract
An improved oil preheater assembly for a waste oil burner that significantly reduces the labor time required to perform routine maintenance. This is accomplished by incorporating a removable cover to directly access the heated oil passages for cleaning thereby providing a simplified method of access to the areas most often requiring routine maintenance. Additionally this design provides an improved electrical control system which significantly reduces electrical energy consumption and the formation of oil carbonization when oil burner heat output is not required. Additionally this design incorporates a nozzle cleaning system for a low pressure siphoning type of discharge nozzle which can remove carbonization and other nozzle contamination and obstructions without the disassembly of components.
