Question about Rinnai Toyostove Direct Vent Heater: Toyostove Laser 73 Shipping
On my Laser 73, when I took the heat exchanger off, I discovered that there is a loose piece of metal inside the lower chamber. It is just sliding around. I'm guessing it is some sort of baffle to direct the air flow into the upper chamber, before being routed down through those 14 tubes, and out through the blower motor.
Any thoughts would be appreciated.
As I mentioned in the last post, you are in need of a big overhaul. The heat exchanger baffle that has become detached is a sign of a heater that has been running very hot. When you get down into the burner you may find a warped bottom. If so, you are looking at a new burner, and heat exchanger. The burner ring and several gaskets will also need replacing. All the above will run around $600+. Despite the high cost of parts you are better off rebuilding than buying new by $1000 or so. When you look at it in the long run you are spending $60 or so a year for the 10 years you have owned the unit. Not bad, I'd say.

you for posting your question here on Fixya.com.
That is the
diverter plate and it should be welded into the header. It helps direct some
of the water flowing thru into the heat exchanger to heat the water. If the weld
fails the diverter can interfere with that flow and cause overheating or poor
flow thru the heater which in turn can lead to the problems you describe.
the inlet side hose once you have blocked the flow of water from the pool and
you should see the diverter in the inlet. If you can move it then it is broken
and needs to be fixed back in place or the whole heat exchanger needs to be
If you can weld then tack in back in place. If not a local rediator repair shop MIGHT be able to fix it or else you need to replace the whole heat exchanger assembly.
