SINGLE LINE (GRAVITY FEED SYSTEM)A. The burner is shipped configured for use in singleline applications. No changes to the oil pump arerequired for use in single line applications.NOTE: If the pump cover (1) is removed for any reason,be sure the O-ring (2), is properly seated in thepump cover (1) before re-attaching the pump cover tothe pump housing. See Figure 40.B. Attach the two PIPE CONNECTORS (6) to thepump SUPPLY and pump RETURN PORTS (5 and7). Attach the required piping to these two pipe connectorsusing the NPT/ METRIC ADAPTERS thatare supplied with the burner.C. Connect the pipe connector to the SUPPLY PORT(5) of the pump. Attach the NPT adapter to the pipeconnector. Attach the required piping to this pipeadapter. Be sure that the plug in the RETURN PORT(7) is tightened securely. See Figure 40. Do not exceedthe pipe lengths indicated in the table 12.TWO LINE (LIFT SYSTEM)A. If a two-line system is required, install the Bypassplug provided. The By-pass plug is installed inthe return port of the pump. A 2.5-mm hexagonal keyprovided with the by-pass plug is to be used to installthe plug. DO NOT use an inch size hexagonal key;damage to the by-pass plug may result. When operatingon a two-line system, supply and return linesshould be the same diameter and both should extendto the same depth inside the fuel tank. Be sure thereare no air leaks or blockages in the piping system.Any obstructions in the return will cause failure ofthe pump shaft seal. Do not exceed the pipe lengthsindicated in the table 13.To install the by-pass plug: (Figure 40)1) Remove the return plug (7)2) Install the by-pass plug (4) using the 2.5 mm hexagonalkeyTable 12SINGLE LINE SYSTEM-PIPE LENGTHSH 3/8” OD 1/2” ODFT M FT M FT M1.5 0.5 33.0 10.0 65.0 20.03.0 1.0 65.0 20.0 130.0 40.05.0 1.5 130.0 40.0 260.0 80.06.5 2.0 195.0 60.0 325.0 100.0Table 132 LINE (LIFT) SYSTEM-PIPE LENGTHSH 3/8” OD 1/2” ODFT M FT M FT M0.0 0.0 115.0 35.0 330.0 100.01.5 0.5 100.0 30.0 330.0 100.03.0 1.0 80.0 25.0 330.0 100.05.0 1.5 65.0 20.0 295.0 90.06.5 2.0 50.0 15.0 230.0 70.09.5 3.0 25.0 8.0 100.0 30.011.0 3.5 20.0 6.0 65.0 20.0ATTENTION:Do Not exceedpipe lengthsindicated in chart!HPHATTENTION:Do Not exceedpipe lengthsindicated in chart!H PFigure 41Figure 4218-CG03D1-442
