Where to buy insulating panels for Burnam gas boilers? The box around and over burner tubes.

in Radiant Heating
I have a Burnham series 3 model 305NI-G made in 2010.
At least one insulating panel broke and fell on top of the burner tubes and was removed.
The part numbers are 72007001 (2), 72007051, 72007052.
Everyone seems to be out. Burnham says they are "obsolete" with no recommended replacement. I tried Radell and they were out but said they would check.
I measured the broken pieces but the thickness varied. Kind burned pieces.

If I could find the dimensions maybe I could buy some ceramic fiber boards and cut them.
Any ideas?

    Called a Burnham distributor. They said to call a HVAC contractor.

    Auer Steel can get those but they're wholesale only so you would need a contractor who has an account with them to buy.
    its a known issue.

    I am NOT saying to do this, or whether it's right or wrong, but on my oil boiler I used fiberglass suspended ceiling panels. Don't forget to remove the white plastic.
    For areas where the fiberglass will not stand up to the heat, try cement board.

    Thanks. I see there are similar or identical panels used in wood stoves but I need to get the dimensions.

    High temp fiberglass doesn't have plastic binders in it, regular insulation does. Some will argue that doesn't make a difference in this application.
