Is my fireplace big enough for the T-33? My opening is 40" wide and 44" tall. I know the depth is big enough. I am just worried about the sides and top because we have already had issues with one that was installed improperly. It is surrounded by columns on either side and a mantel above. We would also like to put a base under it if possible. I can send a picture if needed. Thanks, Racheal Primm
