I have an 11 year old Keystoker AX-120 Hot Air Furnace that now has about a 2' hole in the heat exchanger. Can this be fixed?
I figured I would get 2 square pieces of steel, each about 4" x 4". I would then place on piece of steel on the inside of exchanger (at hole) and the other on oustide of exchanger (hole). I would also put fiberglass mesh between steel and iron to prevent galvanic metal reaction.
Lastly, I would have hole in center of each metal plate, in which I would insert a nut, bolt and washer, and tighten snug.
Would this work?

That Should work.
or you can also put some hi temp silicone between the plates or go to a local Auto Parts store and get some Muffler Cemet/putty or they make Stove Cement or Stove Pipe Sealant at any hardware/stove store.

The heat exchanger is cast iron? I would find a piece of cast, grind the hole and/or piece and braze it in place. I would not use fiberglass in the manner you describe nor would I bolt the patch in.TamaquaMan wrote: I figured I would get 2 square pieces of steel, each about 4" x 4".

If the exchanger is steel, weld a patch in.
You better go over the whole thing with a chipping hammer to make sure it is worth saving, your life is.
