Sunray Bantam burner

Steamhead (in transit)

http://www.oiltechtalk.com/pages/oldburners/abcsunraymodel-fcbantamseries.pdf

The important thing to remember is that this burner does not always use the same nozzle spray angle for all chamber depths. Whereas the Beckett AF/AFG with F-head generally uses an 80° nozzle, the FC might use an 80° on a shallow (from front to back) chamber and a 60° or even 45° nozzle if the chamber is deeper.

Also remember to adjust the "C" dimension (head position) according to the firing rate. The head should be all the way forward at lower rates, and further back as the rate goes up. This adjustment is made by loosening the Allen screw on the nozzle tube clamp at the front of the burner and sliding it forward or back.

I'd also suggest adding an oil-delay valve such as a Honeywell V4046A (with a primary that does not have a built-in delay) or V4046B (with a primary having built-in delay such as R7184 B, P or U). This goes a long way toward cleaning up the start and shutdown periods of this or any oil burner.

I have an FC on my own boiler, and if it's set up properly it burns as well as a Beckett.

I have a Sunray Bantam New Yorker Burner.
It's about 23 years old.
It has trouble firing.
What are the setting suppose to be for the following:
1- spacing between electrodes ?
2- spacing from flat of nozzel, to electrode tips ?
3- height electrodes s/b above nozzel center ?
4- distance from flat of nozzel to flame retention ring ?
