My general sense is that you are talking about a name your poison type situation as Propane stoves
are not vented to the exterior either and they do have a tendancy to blow up. As I have said before here, every sailboat that has exploded I have direct knowledge of (with two posible exceptions) have had diesel engines and propane stoves
. I have spent days searching for propane leakes and frankly would never have a boat with a propane stove
. I think they are too dangerous.
