Two-Pipe System

When using a two-pipe system (see figure 16) with the oil tank below the level of the burner, use a single-stage fuel pump in lift conditions of up to 10 feet (3 m) and/or a vacu- um of 10" (254 mm) Hg or less. Use a two-stage fuel pump when lift exceeds 10 feet (3 m) and/or a vacuum of 10" (254

mm)Hg to 15" (381 mm) Hg. Both conditions require that you use of a two-pipe system, which consists of a return line that purges the fuel pump of air by returning it to the tank. To determine the run and lift for piping, refer to table4

Use continuous lengths of heavy wall copper tubing or steel pipe for oil supply pipe. Install oil supply pipe under floor or near walls to protect it from damage, Avoid running pipes along joists or reverberating surfaces. Always use flare fittings. All fittings must be accessible, Do not use compression fittings.
