  • Ceramic wall spacer kit
    Patent number: 4418679
    Abstract: A mounting kit for stove boards includes ceramic spacers separating the board from a wall so that cool air can circulate behind the board and spacing cradles supporting the board off the floor so air can additionally flow beneath the board. Mounting brackets touch only ceramic surfaces of the spacers so that there is no metallic conduction of heat into the wall.
