Surburban SW6D 6.0 G Water heater turning off after 3 min

Hello Doug!

Well, that seems to have been the issue, the hot water tank was bypassed. This doesn't make a lot of sense, because I drained all of the water earlier and then refilled the tanks yesterday..... then checked the water tank and it had water in it... so, I just assumed everything was normal. I haven't used the trailer really in 6 years, so it appears I have some catching up to do, and need to become more familiar with it..

Thank you very much for your input, and solution!
