Electrode Setting; Turbulator Setting; Oil Line Connections - Riello Burners BF3 Installation Manual

IMPORTANT: THESE DIMENSIONS MUST BE OBSERVED AND VERIFIED
A) Loosen NUT (1), and then turn SCREW (2) until the INDEX
MARKER (3) is aligned with the correct index number as per
the Burner Setup charts, on page 14.
B) Retighten the RETAINING NUT (1).
NOTE: MODEL BF3: Zero and three are scale indicators only.
From left to right, the first line is 3 and the last line 0.
MODEL BF5: Same as above except scale indicators are 0 and 4.
WARNING: The burner is shipped with the pump set to operate on a ONE-line system. To operate on
a Two-line system, the by-pass plug (3) must be installed.
To install the by-pass plug:
1) Remove the plug from the return port of the pump.
2) Insert the by-pass (3) plug into the return port of the pump and screw into place.
3) Connect the return line connection pipe (4) to the return port of the pump and tighten securely.
NOTE: Pump pressure must be set at time of burner startup. Attach a pressure gauge to the
PRESSURE PORT (2) for pressure readings. All pump port threads are British Parallel thread design.
Direct connection of NPT threads to the pump will damage the pump body. Riello manometers and
vacuum gauges do not require any adapters, and can be safely connected directly to pump ports. An
NPT (metric) adapter must be used when connecting other gauge models.
