| + | * While watching the flames, when the main blower starts, the flames are heavily pushed back away from the heat exchanger on two of the three flames, proving a Heat Exchanger failure. (I got hints on how to determine Heat Exchanger failure by watching a couple of YouTube videos.) | ||

I'm thinking that the problem is leak between the intakes of the heat exchangers and the large metal plate. It was very rusty at this joint, and there was a lot of water on exchangers 2 and 3.
