Robertshaw 4200-503 Gas Thermostat

Ensure precise thermal regulation in demanding kitchen environments with the Robertshaw 4200-503 Commercial Gas Thermostat. Engineered for high-capacity performance, this FDTH series gas thermostat (Body Type #1) operates within a 300°F to 650°F temperature range, making it a critical component for deck ovens, convection units, and ranges. This heavy-duty gas control utilizes a modulating snap-acting bypass to maintain stable temperatures under heavy load. It features 1/2" NPT inlet and outlet ports with a side pilot outlet, designed for seamless integration into Baker's Pride M1005A and M1005X systems, as well as several models from Garland and Vulcan.

Built for the professional field, the Robertshaw 4200-503 includes a 48-inch capillary tube and a durable 3/16" x 15-3/8" nickel-plated bulb for accurate sensing. The 4-way mounting capability simplifies installation in tight equipment chassis. Technicians can easily access the pilot and bypass keys, which are slotted for straightforward front-facing adjustments. By modulating the main gas supply while managing the bypass with snap action, this commercial oven thermostat prevents wide temperature swings, ensuring consistent bake results for high-volume operations.

• Broad Compatibility: Direct replacement for Bakers Pride M1005A, 800-9304, and Johnstone F16-556.
• Rugged Construction: Features heat-resistant materials tailored for high-ambient commercial kitchen heat.
• Precision Control: Pilot and bypass keys are accessible for fine-tuning gas flow from the front dial.
• Flexible Installation: 4-way mounting position accommodates various oven manifold orientations.
• Reliable Sensing: 48" capillary provides ample reach for remote bulb placement in large oven cavities.

Is this thermostat compatible with Natural Gas and LP?
Yes, the 4200-503 is designed to modulate gas flow for both Natural Gas and LP systems, provided the proper orifices are used downstream.

Can I use this for lower temperature applications?
This specific model is calibrated for a high-heat range of 300°F to 650°F. For applications requiring lower settings, a BJWA series or different FDTH calibration should be used.

What should I check if the pilot won't stay lit?
Verify the side pilot outlet connection and ensure the thermocouple or thermopile is generating sufficient voltage to held the safety magnet, as this thermostat works in conjunction with the safety valve system.
