Its been a while since I rebuilt a combustion chamber in a boiler . Do you still use vermiculite to fill around the box or is there a new product out there that works better? Thanks for any assistance Fred

Fred,

What is the model of the boiler. Some can be replaced with a Quickee 100 or 200 series. The is also kaoboard in various thicknesses along with dry and wet blanket material. The interlocking brick kits should be backfilled with vermiculite. The Quickee series should not. Lynn manufacturing is just one company that comes to mind right off the top of my head.

Thanks for the responce the firepot is existing 2" board in very good condition . All I want to do is fill in around it with new material. I allways used vermiculite in the past but just wondered if there was anything I was missing? Thanks fred

Fred..

Whenever I do backfill a chamber with vermiculite, I cap it off with smooth cote or some other high temp cement. This makes for a neater job and helps burn off if the reset is pushed too many times.
