I just changed a heat exchanger on a Rheem RTU Model RRGG-10E43JKR.
I have a question about the panels where it exhausts,
you have the plate to separate the fan and exhaust with an angled deflector at the heat exchanger ports on the bottom.
then there is a panel that sit on the top of the ports that covers approx. half of the port.
Does this sound correct. I did install it the way I took it apart. The unit is a little old and way to many hands in it
if someone has a pic of the exhaust section please upload or a parts diagram.
