Hello all, have been researching for 2 years and the tax credit persuaded me to pull the trigger on an insert, too much heat going up the chimney, couldnt take it any more.The forum has been a wealth of info.Thanks to all. Purchased a super 27 PE insert, have discovered the clearance to bend the ss liner is to tight to make the turn into stove. There is 3 inch piece of angle iron, and a course of brick below the damper in the way. I am thinking i have to cut out the angle iron and chip out the brick to make room for the ss lining. Is this a normal situation?
