Oil Tanks And Piping - Bradford White 30S Installation & Operating Instruction Manual

OIL TANKS AND PIPING

IMPORTANT!!
The instructions in this Section are general guidelines. The instructions for
the specific pump installed on the burner that you have purchased should
take precedence over the instructions given below. Read all of the
instructions provided with the burner before continuing with the installation.
A. Miscellaneous Information: If suction and return lines are less than 30
feet in length, 1/2" OD tubing may be used, but never smaller; however,
when the oil line is 30 feet or over, 5/8" OD tubing is recommended.
Where basement oil storage tanks or oil storage tanks installed above
the burner are used, and/or when the oil flows by gravity to the oil pump,
a single-stage fuel unit with a single oil line to the pump may be used.
Avoid as many connections as possible in the suction line and make up
all connections as tightly as possible, using a good pipe joint compound
for oil on all pipe threads. To minimize the possibility of air leaks, tighten
packing gland on any valve installed in the suction line. Also, be sure to
tighten the cover on the oil filter, as filter gaskets often shrink. Check for
kinks in the oil lines as well as for possible air pockets and for loose
connections. Underwriters' Laboratories requirements now in effect
stipulate a bottom outlet on all 275 gallon oil storage tanks. This is to
prevent the accumulation of condensation, which causes the tank to
rust. A water trap can be installed at the oil storage tank outlet to
prevent the water from entering the burner. There are a number of
additives on the market that can be added to the oil storage tank with
the fuel oil. These additives hold the water in suspension and allow it to
pass through the burner. Consult a local fuel oil dealer for information
concerning the use of these additives.
B. Single Line System: NOT RECOMMENDED WHEN IT IS NECES-
SARY TO LIFT THE OIL. This type of installation is used where the oil
storage tank is above the burner and gravity oil feed to the burner is
permitted. The oil outlet and the line should be taken from the bottom of
the tank. This line should have a gradual slope downward of
approximately 112" per linear foot or more to a point directly below
where it is connected to the burner. A shut-off valve should be installed
in the line.
C. Two Line System: If oil storage is buried or if a suction line is long, it is
recommended that a two-stage fuel unit with a two line (suction and
return) installation be installed. For Suntec (Sunstrand) fuel units, insert
the bypass plug through the return port and turn tight. For Webster
pumps, bypass plug comes installed.
