I am new to the site and looking for help. We have a Grandma Bear stove but not like any I've seen pictured so far. Ours has a box over the rear air inlet that goes up to the flue. We also have two rows of brick on the sides making it difficult to set a baffle on those. I saw the post where the baffle was notched around the box but I am wondering if anyone has an idea how to support the baffle. Is it important for the baffle to be at an angle or could I set it flat on top of that second row of bricks? I realize I may need to cut the bricks down a little to keep enough clearance for the flue. Thanks for any help!
