4659 Premix Gas Tunnel Burners consist of a burner nozzle, mounting plate and tile. These burners operate on an air-gas mixture as supplied by North American 3065 Aspirator Mixers or similar mixing devices. When sealed, they prevent air infiltration and may be used on furnaces requiring controlled atmospheres and positive or negative chamber pressure s. The burner tiles are rated at 3200°F maximum operating temperature. The burner mounting plate includes a slip-fit hole
