Set dimension Z
Loosen 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 fl at
area of front face of head) is correctly set, tighten acorn
nut c.
Attach the oil line from the oil valve to the nozzle line end.
Tighten securely.
Before 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.

Install the oil tank and oil lines in accordance with all
applicable state and local codes.
Size the oil supply and return lines using the guidelines
given in the fuel unit literature included in the literature
envelope. Oil line fl ow 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 fl ow rate.
Use continuous lengths of heavy-wall copper tubing,
routed under the fl oor where possible. Do not attach fuel
lines to the appliance or to fl oor joists if possible. This will
reduce vibration and noise transmission problems.
Install an oil fi lter sized to handle the fuel unit gearset fl ow
capacity (Table 2) for two-pipe systems. Size the fi lter
for the fi ring rate for one-pipe systems. Locate the fi lter
immediately adjacent to the burner fuel unit.

Carefully install the oil supply lines, fi ttings and com-
ponents using the guidelines provided in this section.
The oil supply must comply with the latest edition
of NFPA 31 (Canada CSA B139) and all applicable
codes.
Do NOT install valves in return lines.
If 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).
