Do Not Install By-pass

Plug with 1-Pipe System

Failure to comply could cause immediate pump seal failure, pressurized oil leakage and the po- tential for a ﬁre and injury hazard.

yThe burner is shipped without the by-pass plug in- stalled.

yIntall the by-pass plug in two-pipe oil supply systems ONLY.

yThe CF500 and CF800 burners are shipped without the by-pass plug installed in the fuel line.

yThe by-pass plug must NOT be installed when using with a one-pipe oil system.

yThe by-pass plug MUST be installed when using a two- pipe oil system.

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 hazards.

yCarefully install the oil supply lines, ﬁttings and com- ponents 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 return lines.

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).

yInstall the oil tank and oil lines in accordance with all applicable state and local 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 2 for the fuel unit gear set capacity - the rate at which fuel is recirculated when connected to a two-pipe system. However, 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 will reduce vibration and noise transmission problems.

yInstall an oil ﬁlter sized to handle the fuel unit gearset ﬂow capacity (Table 2) for two-pipe systems. Size the ﬁlter

Table 3. Fuel Unit gearset capacity

A2YA-7916	20
B2VA-8216	21
B2YA-8916	25
B2TA-8248	21

for the ﬁring rate for one-pipe systems. Locate the ﬁlter immediately adjacent to the burner fuel unit.

yInstall two high-quality shut-off 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.

yOne-pipe systems – See Figure 8 for the fuel ﬂow path. y Figure 7 is based on type B fuel unit.

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

yTwo-pipe systems – See Figure 9 for the fuel ﬂow paths

for two-pipe oil systems.

y Figure 9 is based on type B fuel unit .

y 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.)
