Hello Everyone im a new member to the site, but have been reading from here for awhile. Love all the great information. My two questions are regarding my new "B" series summit im running for its first season. First off, no problems with heat or operation, love this beast. When the stove is not in operation I can hear the ebt flapper constantly flapping around making annoying sounds with the wind outside. Is this normal? If it is, its quite annoying since the stove is centrally located on first floor. Second question is, when the stove is cooling down from cruising temps to reload temps I hear a few kind of loud pops and bangs. Im assuming its metal contracting somewhere. Just worried about the steel stressing over time I guess. I traded a Regency S2400 for the new Summit this year and this thing is just a totally different animal. Thanks for any replies
