The Wood Stone WS-MS-4 Mt. Chuckanut 4' Stone Hearth Oven is a commercial pizza oven designed for professional foodservice operations requiring versatile cooking capabilities, durable construction, and multiple fuel configurations. Featuring a 37-inch-diameter oven floor with a 7-square-foot cooking surface, the oven incorporates a monolithic 4-inch-thick cast-ceramic hearth and dome. A tensioned steel exoskeleton surrounds the hearth and dome perimeter for structural integrity and longevity, while spun ceramic fiber insulation helps retain heat within the cooking chamber. The galvanized steel exterior, stainless steel service panel, and open black painted steel stand provide durable construction for commercial kitchen environments.

The Mt. Chuckanut 4' is available in gas-fired, wood-fired, wood-fired with gas assist, and combination configurations. Gas-fired models feature an easily adjustable radiant flame positioned at the rear of the cooking chamber, allowing operators to balance radiant top heat with heat conducted and radiated from the oven floor. Radiant Flame and Underfloor IR (RFG-IR) configurations incorporate a thermostatically controlled infrared burner beneath the oven deck to support high-production cooking with reduced heat recovery concerns. Wood-fired models provide traditional wood-burning operation, while wood-fired with gas assist configurations use an underfloor infrared burner and require a wood fire. Combination models allow wood burning alongside gas-fired operation for additional cooking flexibility.

The WS-MS-4 accommodates approximately eight to ten 8-inch pizzas, five to six 10-inch pizzas, four 12-inch pizzas, or one to two 16-inch pizzas. Its 19.75-inch-wide door opening provides access to the cooking chamber, while the adjustable flame controls and digital controller support convenient operation on applicable configurations. The oven requires only 1 inch of side clearance to combustible materials and arrives completely assembled for installation. ETL Listed and manufactured in the USA, the Wood Stone Mt. Chuckanut 4' combines traditional stone hearth cooking, flexible heating options, and robust construction for professional pizza operations.
