I know this sounds strange but I’m thinking about installing a grill in a wood burning, zero clearance fireplace. I want to use the Majestic Biltmore 42. Is the chimney pipe rated for cooking? If not can I change the pipe to one that’s suitable? Finally, the grill has a control arm that connects to a wheel that raises and lowers the grill. I’ve attached a picture. I realize puncturing the wall of the firebox would void the certification. Still, isthere any way to do this safely? I won’t go ahead with anything that’s not safe. Right now I’m just trying to get some information. Any advice?
