Seneca RB hot front bathroom fix
On our 2018.5 37RB, the front bathroom has one heat vent that makes the bathroom extremely hot when running the gas furnace. I had seen others mention this about the RB model. I started looking into this and I found that the bathroom duct was a straight run from the furnace and was the only duct on the run. I started by removing the panels from under the sink and discovered that the blanked off panel on the base of the cabinet to the right of the sink was wide open with just a few wiring harnesses running through it. I cut the foil duct under the sink and installed a tee fitting, then on the outside wall under the control panel, I bored a 4” hole for a new vent location and connected the duct off the tee to the new vent. I moved the original vent to the outside wall and put a new one in the bathroom that was adjustable. With the new vent in the outside wall turned the right direction, it blows right toward the dinette which works perfect and with the adjustable vent in the bathroom you can adjust to how much heat you want in there.....turned out great and was pretty simple to do. I have read some posts that mention that the K model has the same issue but I have not seen if something can be done on the K model.
