While gutting the back end of my 76 PBI noticed this duct was not terminated anywhere. It is just laying there. Looks like it never was terminated. The PO is my father in law and he does not recall ever being back there. Any clues where this should have been terminated?
My '76 Palm Beach was just like yours. That's the bathroom heat vent coming from the booster fan behind the stove. On the outside wall behind the toilet is the vent. I added more line and connected the two. All that distance and turns results in not much airflow but on the COLD mornings the seat is a bit warmer!
