Should the room my NPS40 is in smell like there is a fireplace in the room? Even after the stove is off for hours the room smells like I was burning in an open fireplace. The room is 25 ft X 20 ft. I have resealed my pipes with silicone, but do get a little smoke when starting the stove. Should you be able to tell there is a stove when you walk in the room?
