Options

A1 = Oil Gun Purge System Items 14, 15, 16 & 17, factory installed. This system automatically cleans out the oil gun upon a "planned" oil burner shut down. When the burner control is turned off while firing oil, the unit is sent to low fire. The pilot is energized, the oil safety shutoff valves close, and the oil gun is cleaned out with atomizing media. The burner shuts down at the completion of this sequence. All the safety limits are monitored during this sequence. If a limit should fail, the sequence is stopped immediately, and all the fuel valves will close.

A2 = Atomizing Steam Pressure Reducing Station - If the atomizing steam supply pressure is over 200 psig, a pressure reducing station will be required. This option includes items 18, 19, 20, 21, 22 & 23, factory installed on the burner.

A3 = Atomizing Media Change Over Equipment - This includes items 24 and 25 shipped loose for field installation.

NEMA 4 - Changes items 3, 4, 10 & 19 to weatherproof (NEMA 4)

Specifications for Atomizing Media Train Piping & Fittings

Schedule 80 pipe with 300# malleable iron threaded fittings.

Supply Pressure

To inlet of atomizing train:
100-200 psig steam at 400 degrees Fahrenheit or less
100-200 psig compressed air
If the available atomizing media supply pressure is greater than 200 psig option A2 will be required.
