Utica Boilers SFE IV Steam 安装指导

• Install oil tank and piping in accordance with 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. 

• Bury oil lines or protect 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. 

• 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, install two stage 

fuel unit in place of single stage pump supplied as 

standard equipment with burner. 

• Verify rotation and speed are the same and pump is 

suitable for burner horsepower rating.

Install oil line filter and shut-off valve in the suction line. 

Install shut-off valves in both suction and return lines at 

the burner for convenience in servicing burner. 
Allow extra tubing at burner so burner may be removed 

from boiler for cleaning without disconnecting tubing. An 

optional flexible oil line is available. See Figures #12 -
