Specifi cations
Failure to properly install the oil
supply system could cause oil
leakage,
puff-back of hot gases, heavy smoke,
asphyxiation, explosion and fi re
hazards.
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 line.
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).
One-pipe systems – See Figure 8 for the fuel fl ow path.
Oil supply connects to one of the fuel unit inlet ports.
Two-pipe systems – See Figure 9 for the fuel fl ow paths
for two-pipe oil systems.
Oil supply connects to one of the fuel unit inlet ports. Oil
return connects to the fuel unit return port. (Install the
