Gas thermostat for commercial ovens
The Robertshaw 4200 gas thermostat regulates burner temperature in commercial ovens using natural gas. It fits equipment from brands such as Blodgett and Consolidated. The unit operates across a 150 to 550 degree Fahrenheit control range. Installers connect it via a half-inch pipe thread.
Capillary length sets installation reach
A 48-inch capillary tube links the sensing bulb to the control head, fixing the maximum distance between the oven cavity and the mounting point. The bulb measures three-sixteenths of an inch in diameter and fourteen and three-quarters inches long, so the oven must accommodate that profile. Routing must avoid sharp bends that could kink the tube. No wireless or electronic signalling is used.
Temperature range decides suitability
The 150 to 550 degree Fahrenheit span is the single specification that determines whether this thermostat matches the oven's required operating window. If the application demands control outside those limits, this model will not function correctly. The RoHS marking confirms restricted-substance compliance. Verify the gas type and connection size before fitting.

Questions about this item
How do I choose between the 150°F minimum and 550°F maximum control temperatures?
The thermostat covers the full 150 to 550°F range in one unit; select the dial setting that matches the oven temperature your recipe or process requires.
What does the 48in capillary length mean once the thermostat is installed in an oven?
A 48in capillary lets you mount the control body up to 48 inches away from the sensing bulb, giving flexibility for routing through cabinetry or insulation.
What does the 1/2in pipe gas connection cap in practice?
The 1/2in pipe thread limits the gas supply line to that size, so the incoming piping and any adapter must match 1/2in NPT for a proper seal.
