Test heat exchanger

While watching a video of Ben tearing apart a furnace for a damaged heat exchanger I was curious of how to check. Hope you find this interesting. Although we don’t test I was interested.

if you have a ferret camera you could put that into the furnace heat exchanger where the burners are and look for cracks. or remove the draft fan and look from there. But its way beyond the SOP.
