•Install two high-quality shutoff valves in accessible loca- tions on the oil supply line. Locate one valve close to the tank. Locate the other valve close to the burner, upstream of the fuel filter.

❏Burner fuel flow

•One-pipe systems – See Figure 8 for the fuel flow paths for high-fire and low-fire operation. Oil supply connects to one of the fuel unit Inlet ports.

Do not install by-pass plug in a one-pipe system. Could cause unit seal failure, oil leakage and potential fire and injury hazard if ignored.

•Two-pipe systems – See Figure 9 for the fuel flow paths for high-fire and low-fire operation. Oil supply connects to one of the fuel unit Inlet ports. Oil return connects to the fuel unit Return port.

By-pass plug must be installed in a two-pipe system. Failure to comply could cause unit seal failure, oil leakage and potential fire and injury hazard.

•Low-fire/high-fire operation – The fuel unit nozzle port pressure is factory set at 300 psig.

•At high fire, full pressure (300 psig) is applied at both oil nozzles, causing full input.

•At low fire, full pressure (300 psig) is applied at one nozzle, causing reduced input.
