Robertshaw 4290-011 Gas Thermostat

The Robertshaw 4290-011 is a high-capacity, snap-action hydraulic thermostat engineered for precise temperature control in heavy-duty commercial cooking equipment. Built for high-demand environments, this GS series gas control features a 3/8" pipe inlet and outlet, supporting a capacity of up to 30,000 BTUs. With a temperature range of 200°F to 400°F, it is the standard choice for maintaining thermal stability in commercial fryers, griddles, and convection ovens. The unit comes equipped with a 30-inch capillary and a 3/8" x 5-3/8" nickel-plated copper sensing bulb, ensuring rapid response to temperature fluctuations by interrupting gas flow directly at the burner. Designed for versatile integration, the Robertshaw 4290-011 gas thermostat is compatible with South Bend, Star, and Wolf Range systems, as well as high-capacity 700-800 series diaphragm valves. Its compact housing allows for installation in limited mounting spaces, while the heat-resistant plastic dial ensures durable field operation for professional contractors and kitchen technicians.

• Snap-Acting Operation: Delivers full gas flow immediately from the off position to ensure rapid heat recovery in high-volume kitchens.
• Extreme Durability: Features a nickel-plated sensing bulb and a 30-inch capillary tube designed to withstand ambient temperatures up to 300°F.
• Wide Compatibility: Serves as a direct replacement for various commercial kitchen thermostats across brands like Hobart, Cecilware, and Jade Range.
• Precision Control: Maintains a strict 200-400°F range, critical for food safety and consistent results in griddles and warming cabinets.

• Does this thermostat require a separate gas cock? Yes, this control does not have an integrated gas shut-off and must be installed downstream from a dedicated gas valve.
• Can the bypass be adjusted? This model supports an optional adjustable bypass key to maintain a minimum flame when the thermostat is satisfied.
• What is the proper mounting orientation? For accurate calibration and operation, always mount the control so the dial shaft is in a horizontal plane.
