I have a Drolet Escape 1400 which I installed this winter and have been thoroughly enjoying. The problem is the humidity in my house has dramatically dropped. I'm looking into the outside air kit as part of a solution to this, but oddly enough on this insert this wouldn't be a sealed connection between the combustion chamber of the insert and the outside air. There is still a pathway from the household air to the combustion chamber via the pathway for the blower circulation. This makes it seem like a nice gapping hole between my house and the outside with nothing more then some plastic shutters on the outside air intake.Why do they design it this way? Is it normal? How do other people deal with low humidity and inserts, considering you can't do the kettle of water trick like a on a stove?
