Robertshaw 4350-128 Gas Thermostat

The Robertshaw 4350-128 is a professional-grade BJ Kit for Griddle systems, engineered for precise thermal management in demanding commercial kitchen environments. This combination gas cock and bypass thermostat provides a reliable temperature control range of 150°F to 400°F, ensuring optimal heat consistency for flat-top surfaces. Designed as a high-capacity commercial griddle thermostat, it supports up to 70,000 BTU/HR, making it a versatile choice for Natural Gas and LP applications. The assembly features a 3/16 inch x 8-5/8 inch sensing bulb and a durable 48-inch capillary tube, allowing for flexible mounting above or below the manifold via a wide flange nipple. This gas thermostat replacement is a functional equivalent for legacy BJ and BJWA series controls, commonly utilized by manufacturers such as Garland, South Bend, and Star Manufacturing. Technicians can utilize the front-accessible pilot and bypass adjustments to fine-tune the modulating seat action, maintaining tight tolerances and improving energy efficiency on the line.

• Universal Compatibility: Serves as a direct replacement for Robertshaw BJWA and BJ series, fitting brands like Imperial, Jade Range, and American Range.
• Precise Modulation: The modulating seat action provides accurate gas flow control to prevent temperature overshooting on heavy-duty griddles.
• Flexible Installation: Features 1/4 inch NPT pipe outlets and a 180-degree rotated housing to accommodate diverse manifold configurations.
• High Thermal Capacity: Rated for 70,000 BTU, supporting high-output equipment without sacrificing accuracy.
• Complete Kit: Includes the Robertshaw 4350-128 dial and all necessary mounting hardware for immediate field replacement.

Is the bulb and capillary tube safe for high-heat environments?
Yes, the 48-inch capillary and sensing bulb are constructed to withstand standard commercial griddle temperatures. Ensure you use a round screwdriver shaft to uncoil the diastat smoothly to avoid crimping the liquid-filled tube during installation.

Does this kit support both Natural Gas and Liquid Propane?
The Robertshaw gas cook control is compatible with both NG and LP fuel types; however, technicians must calibrate the bypass flame according to the specific gas type and manufacturer specs once installed.

Can this thermostat be used for commercial ovens?
While functionally similar to oven controls, the 4350-128 is specifically calibrated for the 150°F to 400°F range typical of griddles. For oven applications requiring higher temperatures (up to 550°F), refer to the BJWA oven series.
