We are planning a new home in the northwest panhandle of florida...........first floor 2500 sq ft with 20 x 20 hearth room (9 ft ceiling)....We can specify a masonary exterior chimney, brick hearth, etc. My wife and I enjoy my uncle's older Ashley wood burning insert in his family room. My question......what kind of specifications should I give to my builder in order to build the proper chimney, hearth, etc to accomodate a current model wood burning insert? We don't plan to heat the entire house with this.......just want the beauty of a wood fire and comfort of an extremely warm hearth room...... We are breaking ground in May so we have time to plan. I know absoloutely nothing about fireplaces and/or inserts. Thanks so much for your input.......ratucker3
