Verify before starting burner:
Should overheating or an emergency occur, immediately:
• Shut off oil supply line valve.
• Under some circumstances power should remain on for
water pumps or blowers. Determine proper response before
attempting start-up.
• If burner fails ignition on several attempts, use burner
blower to purge appliance chamber before restart.

Two-line fuel system requirements
See Figure 15 and Table 4. Use Table 4 only for burners equipped with
Suntec fuel units. For burners using other fuel units, read the fuel unit
manufacturer’s data sheet to determine maximum lengths and lifts.
The standard burner fuel unit is a single-stage, 3450-RPM oil pump. Use
this fuel unit only on two-line oil systems that do not exceed the total
tubing lengths allowed in Table 4 (for Suntec fule units only). For longer
systems (or where lift exceeds 10 feet), replace the one-stage fuel unit
with a two-stage unit.
Always size fuel lines using an oil flow rate based on the fuel unit gearset ca-
pacity, not the burner firing rate. See fuel unit data sheet for information.
Install the fuel unit bypass plug when connecting to a two-line
system. The plug is shipped in a bag attached to the fuel unit,
along with a fuel unit data sheet.
