Changing the heater exchanger in a Rinnai on demand water heater

Changing the heater exchanger in a Rinnai on demand water heater

Electrolysis damaged this heat exchanger. I found this to be the third heat exchanger to be installed. There was missing screws and and out of place screws. I took me 3.5hrs to do this. And it was cost effective as the Rinnai people was nice enough to send the warranty replacement.
