In the bedroom of the 2600RB are two round vents on the wall. One is down near the floor and the other is about 2 feet up from it. The top one has no hose connected to it. When I remove the drawers in the kitchen by the Sink, I can see the Propane heating unit and its plenum where there are 4 Silver ducts coming off of it. One duct runs under the sink to the cabinet wall, one runs to the shoe storage area near the Entrance door, one to the bathroom, and one to the bedroom. If you get a mirror and look down near the Heating unit, you can see where the Hot and Cold water lines for the kitchen faucet run down through about a 3" hole in the flooring. So you can see through the hole down into the underbelly area. My first thought is there should be some insulation (spray foam perhaps) around the plumbing. But perhaps this hole is left open to allow heat to get down into the underbelly. We have the 4 seasons package. I know this may be hard to decipher, I should have taken some photos.
1. Is this hole not insulated intentionally to let warm air into the underbelly?
2. Is the higher vent in the bedroom wall with no ducting connected a "Return Vent" or something?
