Robertshaw 4200-508 Gas Thermostat

The Robertshaw 4200-508 is a professional-grade FDH gas thermostat designed for high-capacity temperature regulation in commercial cooking equipment. As a Body Type #2 control, this unit features 1/2-inch side inlets and outlets to ensure high flow rates for demanding appliances like deck ovens, convection ranges, and baking units. Utilizing a 48-inch capillary and a 3/16-inch x 14-3/4-inch nickel bulb, it delivers precise feedback and provides a robust temperature range of 300°F to 650°F. This commercial cooking control is engineered with a side-mounted pilot outlet and includes accessible pilot and bypass adjustment keys, allowing technicians to fine-tune the burner profile directly from the front of the unit. The modulating snap-acting bypass mechanism ensures efficient gas flow management, maintaining consistent thermal performance under heavy load conditions. Whether you are performing a Robertshaw gas thermostat replacement or a new installation, the 4-way mounting capability provides the versatility needed for tight equipment footprints.

• Dual Control Logic: Modulates the main gas supply while managing bypass gas under the same thermostatic action for tighter temperature tolerances.
• Adjustment Accessibility: Slotted pilot and bypass keys are accessible from the front, simplifying field calibration during initial setup.
• High Heat Resilience: Constructed with rugged, heat-resistant materials specifically for the intense environments of commercial kitchens and bakeries.
• Broad Compatibility: Serves as a direct replacement for various Blodgett, AllPoints, and Uni-Line components.

Is the dial included with this model?
This part usually requires a slip-fit dial; while some kits include a black 300-650 range knob, compatibility with existing equipment shafts should be verified at the time of installation.

Can I use this for low-temperature applications?
The 4200 series allows for low-temperature control; however, this specific 4200-508 model is calibrated for a higher range of 300°F to 650°F, making it ideal for ovens rather than warming cabinets.

What is the benefit of the side pilot outlet?
The side pilot configuration simplifies plumbing in certain burner manifolds where rear access is restricted, providing a more reliable connection for the pilot line.
