for the fuel unit gearset capacity - the rate at which fuel is recirculated when connected to a two-pipe system. Size two-pipe oil lines based on this flow rate.

•Use continuous lengths of heavy-wall copper tubing, routed under the floor where possible. Do not attach fuel lines to the appliance or to floor joists if possible. This will reduce vibration and noise transmission problems.

•Install an oil filter sized to handle the fuel unit gearset flow capacity (Table 3) for two-pipe systems. Size the filter for the firing rate for one-pipe systems. Locate the filter immediately adjacent to the burner fuel unit.

•Install two high-quality shut-off 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 path.

•Figure 8a is based on type H fuel units.

•Figure 8b is based on type B fuel units.

•Oil supply connects to one of the fuel unit inlet ports.

•Two-pipe systems – See Figure 9 for the fuel flow paths for two-pipe oil systems.

•Figure 9a is based on type H fuel units.

•Figure 9b is based on type B fuel units.

•Oil supply connects to one of the fuel unit inlet ports.

Oil return connects to the fuel unit return port. (Install the by-pass plug in the fuel unit for two-pipe sys-

tems.)

•Nozzle pressure – The fuel unit nozzle port pressure is factory set at 300 psig. Some original equipment manufac- turer burner applications may call for a lower pressure to obtain a required firing rate. Do not change this pressure unless directed to do so by the appliance manufacturer.
