An amulet would be a good idea. They make specific ones for beckett, carlin and riello.

    Air tube protrusion

    I took a look at a friend's old coal steam boiler, which had been retrofitted with a retention head oil burner many years ago (Beckett burner mounted on the coal feed door). He's had regular problems with the burner head sooting up badly. The first thing that hit me was the air tube sticking into the firebox about an inch beyond the thin layer of insulation on the inside of the door. I'm rather new at this oil heat stuff, but remember in my classes and in the Beckett literature, a recommendation that the air tube be held back from the firebox 1/4". On the other hand, I'm not sure where the "firebox" starts, since the door is back from the cylindrical ID of the boiler a few inches, so the air tube is back from the cylindrical ID maybe 2".

    I thought the air tube was to be protected from the radiant heat of the firebox by surrounding it with insulation. Should the air tube be pulled back into the insulation? Should more insulation be added to the inside of the door (there's about 1/2" now)?

    It's been like this for over 20 years. I would think if it was not proper, the service techs would have said something about it, or changed it by now. Anybody have experience with this??

    beckett in the door

    this is a common practice with old boilers. Mounting a gun burner in the door will increase operation efficiency by not having to heat the boiler base. You are correct about the blast tube.It should be insulated. Either thicken the door insulation or get some insulation for the tube. Lynn used to make a "donut" of insulation for this purpose. Haven't seen any for a long time but some may be available. the end of the blast tube should be set back 1/4" from the surface of the insulation as you mentioned.
