Rinnai v53e Propane model. Unit shuts off 2mins into shower. Minimum flow related.
Hi, I have a Rinnai v53e that will shutoff mid shower (right after you shampoo lathered you hair and are blind) and give no error code. I have done extensive trial and error testing and have narrowed it to the minimum flow. I tried removing the restrictor disks on the shower head and the problem goes away. The problem seems to only occur in the warm months (guessing input water temp related, unit is in Florida where city water is really not that cold). Unit will operate fine as long as I run the shower head on full blast HOT water, so it feels like bathing infront of a pressure washer. The unit is hot water only for a single family house. Unit never shuts off from dishwasher or sink usage. Unit seems to operate fine if BOTH showers are running. I have had propane company test gas flow (inches?) and it is more than sufficient per then tech. My question is..can I adjust the temp of the unit to compensate for this and lower the minimum flow requirement so I dont have to have my skin blasted off by insane water pressure.
Thank you for any input.
