Hi PennyJo, If you're talking about the one I posted, it was that price, but was returned to Home Depot W/O the remote, and was reduced to $340. We bought it at the reduced price.
I called Rheem, and a good man there sent a remote. When we tested it, installed on a board outside, there was a bad leak inside,that may be why it was returned, There was a missing Clip that held the copper line to the condensation tank. The neoprene seal was in good shape and the clip was lying inside, slightly expanded, I bent it closed and snapped it in place, dried the interior with warm air, plugged it in, turned on the LP gas and water and it fired up, no leaks.
It vents with 3" PVC Pipe, both the intake and exhaust.
Our water, tank type, is working well, Carol who has a ranch west of us, has been without hot water, I hear for weeks, I'm sure she will be pleased with it, she can give us a run in shed frame, she's a lot of metal, laying around there, that way she won't feel like a charity case, she wouldn't like that. I'll put it in for her, she must be heating water on the stove.
She'll think she's doing us the favor, she will be really.
