Need help with old Whitfield Advantage II burn pot

[MattM]

Hello all. I have a 1989-1990 Whitfield advantage II my dad bought brand new. It's finally burned a hole in the burn pot after 25 or so seasons of actual use. It's used to heat the recreational/add on living portion of our garage, which is about 1100 sq ft by itself. I purchased a replacement drop in burn grate that is identical to what is in the pot, but the original is welded in. I can't find much on this style of burn pot/plenum as it seems they didn't use it very long. The serial # of the stove is in the 17,000 range. It's been a pretty decent stove over the years, it's needed the nylatron auger housing bushing upgrade and a convection blower motor once, that's about it. Is it normal for these original burn pots to be welded in? I find it pretty odd that it is but it's how it came. I am a bit puzzled on what to actually do with it. Attached are a picture I found online of the same burn pot I have and the replacement insert I bought. Dimensions of new insert are correct. I can't seem to find a new burn pot body at all?

So what you're looking for is that replacement base plate, as it swaps out your welded one with the updated model with removable burn pot.

From what I read the switch to the removable burn pot happened within the first year or two mid production- likely for what you're experiencing now, difficulty replacing worn parts.
