Set dimension Z

yLoosen fastener c in Figure 6. Slide the nozzle line and plate assembly until dimension Z in Figure 5 is 1-1/2” ±1/16”. When dimension Z (from end of air tube to ﬂat area of front face of head) is correctly set, tighten acorn nut c.

yAttach the oil line from the oil valve to the nozzle line end. Tighten securely.

yBefore proceeding, check dimension Z once again. Loosen acorn nut c if necessary to reposition the nozzle line. Once dimension Z is set, do not loosen the acorn nut c again. Note that for the setting of fastener d, refer to Initial Head Position procedure on Page 10.

Insert burner

yPosition the burner in the front of the appliance and loosely tighten the nuts on the mounting studs. The burner should be pitched downward 2° as shown in Figure 3.

ySecure the burner to the appliance by tightening the nuts on the burner ﬂange mounting studs.

Fuel unit by-pass plug

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 CF375 burner is 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. 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 for the ﬁring rate for one-pipe systems. Locate the ﬁlter immediately adjacent to the burner fuel unit.
