7.0 FUEL SYSTEM
The fuel system piping must comply with the pump manufacturers’ specifications which are
included with the burner. In addition, all fuel system piping must comply with local codes and
ordinances.
•
The quality of your fuel oil is of great importance. For most instances your burner is
designed to burn clean water free #2 fuel oil.
•
The oil supply line should be constructed of seamless heavy wall copper tubing with flared
fittings. Only oil resistant pipe dope should be used on threaded connections. The use of
Teflon Tape will void manufacturers’ warranty. Lines must be airtight, clean and free of
kinks. All joints and
threaded fittings must be checked for leaks. A vacuum gauge should be
employed when testing the installation. It is recommended that older fuel lines be replaced.
•
A two pipe system should only be used when the oil supply is well below the pump. A return fuel
line may be used on inside installations where the tank level is below the level of the burner. The
return line must be equal in diameter to the suction line. The minimum size for the oil line is 3/8”
copper tubing.
•
A oil de-aerator is recommended when the oil supply line is located 5’ below the burner.
•
Shut off valves must be installed in the supply line at or near the oil storage tank and at the burner
in compliance with all codes. Inspect the shut off valve spindle packing for tightness to insure that
there are no air leaks. The valve must always be shut off if the burner is shut down for an extended
period of time. The burner should be tagged to indicate that the fuel supply has been closed off.
The electrical circuit to the burner must be cut off by removing the fuse or circuit breaker to insure
that no operation of the burner will occur while the fuel supply is shut off.
•
Only fuel storage tanks bearing the Underwriters Laboratories label and accessories approved as
prescribed by local code may be used.
