We just moved and there is a fisher insert in the fireplace. I was up on the roof tonight to clean the liner but there is no liner and no cap. I guess this is a dumb question, but where does the rain and snow go if it is open to the world? Also, I burned a small fire tonight and every time I opened the door a big puff of smoke came out into the room. Any ideas there? We have snow coming and want to use this stove. Any advice is appreciated. This is just a quick fix as we are about to bite the bullet on a blaze king princess!
