    Its been awile since I have worked on one of these, In alot of jobs the burner itself was supported by the stand as you can see, where the burner tube is attached to the boiler is sealed with refractory type cement which you need to remove to get burner out. The burner may be attached with clip style fasteners to the boiler, Before you remove the burner order some Greenpatch 421 cement  5 gals is about $65.00.  you will need this when reattaching the burner to seal the blast tube to the boiler. Alot of these old burners were set in place like this, now day burners come with mtg. plates and tube plates for most installs.   Before pulling burner check for an access panel to get to pilot assy. on back or side of burner, I used to have an I.O.M on this burner sorry could not find.

    That one's been around for a while

    but the manufacturer probably still has something on it:

    Oil & Gas Burner Service
