J. LIGHT FUEL OIL PIPING SYSTEM
1. Hauck recommends using a flexible connection to connect the oil line to the oil manifold
on the burner. A flexible connection will reduce vibration stress on the oil manifold.
Refer to Table 7 for recommended flex connection.
Table 7. Recommended Flexible Oil Hose Size
2. For recommended piping sizes see Table 8. Before attaching fuel lines, purge the
piping to remove scale and dirt that could clog and damage oil equipment. Follow Figure 5
for the suggested piping layout.

3. Adjust the bypass relief valve until required oil pressure is achieved. See Table 9 for
approximate settings. Final oil pressure will have to be adjusted to attain desired burner
output and stack exhaust gas analysis.

NOTE
Hauck recommends the use of oil manifolds that meet
NFPA guidelines. NFPA requires two safety shutoff
valves piped in series in the burner’s main oil line. A
low/high oil pressure switch must be interlocked with
the burner’s safety shutoff valves. Hauck oil manifolds
have been designed to ensure compliance to NFPA
requirements.
WARNING
Adjustment of this equipment and its components by
unqualified personnel can result in fire, explosion,
severe personal injury, or even death.
