We just lit the water heater for the first time. I don't know if I posted it a while ago, but the water heater that was in it showed signs of electrical meltdown and we didn't want to trust it, especially considering the control module was $200+. We found one pulled from a 2022 RV for $170 locally and bought it. Just a little bit longer than the other one but narrower. We got it mounted a while ago but never got to test it until today because it needs to be filled to fire. We just got done the plumbing and decided to fire it. Hooked up 12v, opened the gas line and within a few seconds the igniter fired, and a couple seconds after that, the burner fired. I spent most of the day yesterday sorting out the rats nest of 12vdc and 120vac wiring that all came together in one spot in the ceiling.
Now there's a nice new switch panel I put together and all the 120vac lines are sorted and connected
The exhaust fans are now set that can be run individually.
Here's the squat test to see if I need to add more air to the suspension with it hitched up. I think it looks good.
We should be ready to roll by saturday afternoon.
