Attachment B - VA Standard Detail SD 235239-04.pdf

This is a technical schematic document, specifically VA Standard Detail 235239-04, depicting a No. 2 Burner Fuel Oil Systems standard piping diagram. The diagram illustrates the complete mechanical and control systems required for a No. 2 oil burner installation, including oil supply lines, pressure control mechanisms, burner components, and associated safety features. Key system elements shown include an oil tank with heating capability, fuel supply pumps capable of 100-300 psi delivery, pressure gauges, flow meters, filters, and a burner assembly with integrated controls. The schematic incorporates two primary oil temperature control systems—one for the main supply and one for secondary oil tank heating—along with return flow mechanisms to the storage tank. Control features include interlock switches for minimum flow verification, differential pressure indicators, automatic shut-off valves, and provisions for both fuel oil and air atomizing burner configurations. The diagram contains detailed notes addressing piping sizing requirements based on burner specifications, steam pressure availability options, and flexibility requirements for connection points. This document serves as a standardized reference for military facility construction and maintenance specifications, ensuring consistency in No. 2 burner fuel oil system installations across Department of Veterans Affairs properties.
