Working on this residential small boiler (America Standard)
that needs new refractory, Unit appx 20 Years old, customer has no intention in replacing at this time.
Problem is i can not locate a supplier in the Toronto area tha deals with this sort of thing,
Could use your help Thanks.....
If this is a wet base boiler
Lynn makes a "universal" chamber that will work
They use the trade name "quickie" probably a #100 or #200 will fit with a little work.
If it is a dry base American Standard You can rebuild chamber with Lynn Kaowool board
Take the existing chamber apart carefully and observe how it is put together. Fabricate the K-board to the same dimensions and make sure you end up with the same thicknesses as the original
