Oil Tank And Piping - UTICA BOILERS SFH-3085 Installation, Operation & Maintenance Manual

• Install burner per instructions provided with burner-in-
a-box kit.
• Install oil tank and piping in accordance with the
National Board of Fire Underwriters and local
regulations.
• Oil storage tank, vent, fill pipe and caps should be as
prescribed by local codes.
• In no case should vent pipe be smaller than 1¼" I.P.S.
Fill pipe should not be less than 2" I.P.S.
• Suction line from tank to burner should be one
continuous piece of tubing to prevent air entering line.
• Suction line, must be ⅜" O.D. copper tubing for runs of
50 feet or less, and ½" O.D. for longer runs. Oil return
line, same size as suction line, must be used on any
installation where bottom of tank is below fuel unit of
burner.
• Oil lines should be buried or otherwise protected from
mechanical injury.
• Flare fittings on all oil lines are recommended.
Compression fittings on suction line often allow air to
be drawn into fuel pump, making it difficult to maintain
oil pressure at nozzle.

OIL TANK AND PIPING

• Do not run overhead fuel lines from tank to oil burner.
• Fuel pump connections and by-pass should be made
according to instructions attached to fuel pump. If
tank is more than 20' from boiler, a two stage fuel
unit should be installed in place of single stage pump
supplied as standard equipment with burner. Make
certain rotation and speed are same and pump is
suitable for burner horsepower rating.
• Oil line filter and shut-off valve should be installed in
suction line. Shut-off valves should be installed in both
suction and return lines at burner for convenience in
servicing burner.
• Allow extra tubing at burner so burner may be removed
from boiler for cleaning without disconnecting tubing.
(See Figures #16 & #17, below).
• Optional flexible oil line is available.
