Beckett CF1400 manual One-pipe Oil System By-pass Loop, Oil Supply/Return Lines, Burner Fuel Flow

Section: Mount the Burner

Special Note: The burner is shipped with a by- pass plug installed in the fuel unit. For low/high operation, the by-pass plug must be left in the fuel unit, regardless of the fuel system used (one-pipe with by-pass loop or two-pipe). Do not remove the by-pass plug.

One-pipe Oil System By-pass Loop

Refer to Figure 9 (item m). Note the addition of a field- installed by-pass loop (use 3/8” copper tubing) from the fuel unit Return port to the Inlet port. This line is required for low/high operation. It simulates the flow of a two-pipe system at the fuel unit.

○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 reduces vibration and noise transmission problems.

○Install an oil filter sized to handle the fuel unit gearset flow capacity (Table 3) for two-pipe systems. However, 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 shutoff valves in accessible locations 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.

Oil Supply/Return Lines

○Install the oil tank and oil lines in accordance with all applicable codes.

○Size the oil supply and return lines using the guidelines given in the fuel unit literature included in the literature envelope. Oil line flow rate will equal the burner rate for one-pipe systems. For two-pipe systems, refer to Table 3 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.

Burner Fuel Flow

One-pipe systems – See Figure 9 for the fuel flow paths for high-fire and low-fire operation. The low-fire by-pass regulation is done internally for type B fuel units. Oil supply connects to one of the fuel unit Inlet ports.

Two-pipe systems – See Figure 10 for the fuel flow paths for high-fire and low-fire operation. The low-fire by-pass regulation is done internally for type B fuel units. Oil supply connects to one of the fuel unit Inlet ports.

Oil return connects to the fuel unit Return port. Do NOT install valves in the return line.
