Hello folks ... I need to apologize ... I have jut violated one of the cardinal tennants of being a guy ... I read the installation instructions for my pellet stove. This was the result of my wanting to verify how to adjust the fresh air intake damper of my stove ... and I think I regret having trusted the "professional installation". According to the Technical Manual for my Regency pellet stove, the manufacturer requires fresh air venting if the pellet stove is installed in a monile home or an "airtight" house, and "strongly recommended" for ALL installations. Since my stove was installed (just prior to Christmas), I have been concerned about the pellet burn. Recently, pellet burn has been rather incomplete. Needless to say, my stove is drawing fresh air from within the house/room where the stove is installed. My questions ... a) If your pellet (or wood) stove is installed without a fresh air intake outside of the house, do you experience complete pellet burn? b) If your stove is installed without a fresh air intake outside of the house, do you (or any family members) experience light-headedness? c) Do you feel it is safe to operate a stove that does NOT have a fresh air intake drawing fresh air from outside the home? Thank you for your time and input!
