Last year I upgraded my open woodburning fireplace with a woodstove insert. The old fireplace had an ash dump with outside access. The new stove does not have an ash dump. It does hoever draw fresh air from the bottom. When I burn to heat the house I end up drawing cold air throughout the house, to prevent this I have opened my ash dump door to the outside. It works perfect while burning. However when I am not buring a strong cold draft can be felt around the stove. Is there any solution to automate or at least operate a damper from inside my house to control the ash dump opening? Also is there any safety concerns drawing fresh air from the ash dump. It is only open to the oustide.
