Connect fuel lines

Fuel unit by-pass plug

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.

Install Oil Supply To

Speciﬁcations

Failure to properly install the oil supply system could cause oil leakage, equipment malfunction, puff-back of hot gases, heavy smoke, asphyxiation, explosion and ﬁre

yCarefully install the oil supply lines, ﬁttings and components using the guidelines provided in this section.

yThe oil supply must comply with the latest edition of NFPA 31 (Canada CSA B139) and all applicable codes.

yDo NOT install valves in the return line.

yIf the oil supply inlet pressure to the pump exceeds 3 psig or for gravity feed systems, install an oil safety or pressure reducing valve (Webster OSV, Suntec PRV or equivalent).

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.

Factory-Installed Pump

Bypass Plug

Failure to follow these guidelines will cause the fuel pump seals to rupture and result in oil leakage, burner malfunction and potential ﬁre and injury hazards.

yModels CF1400 and CF2300 are shipped with the pump bypass plug installed.

yDo not remove the bypass plug from the pump. It is required for step-ﬁring (Lo/Hi) operation.

yDo not operate the burner unless a return line or bypass loop is installed or the pump seal will rupture.

yCarefully comply with the following instructions provided in this section of the manual.

Oil supply/return lines

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

ySize 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.

yUse 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.

yInstall 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.

yInstall 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.

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.

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

yAt high ﬁre, full pressure (300 psig) is applied at the oil nozzle, causing full input.

yAt low ﬁre, the by-passing is done inside the fuel unit when the by-pass valve operates.

yThis by-passing of oil reduces the oil pressure at the nozzle (to between 125 psig and 175 psig), reducing the input.
