What is the maximum temperature for the high limit on a converted gravity furnace?

The maximum temperature for the high limit on a converted gravity furnace is set at 350°F. This threshold is important for safety and efficiency; it helps prevent overheating, which can lead to system malfunctions, increased wear on components, or even hazardous situations, such as fires or carbon monoxide buildup.

Gravity furnaces rely on natural convection to circulate heat, and maintaining appropriate limits is crucial to ensure that the system operates effectively. If the temperature exceeds 350°F, it could indicate issues within the furnace system, such as improper airflow or malfunctioning controls, necessitating immediate inspection and potential intervention to avoid damage or safety risks.

Setting the high limit at 350°F helps to ensure the furnace operates within safe parameters while also providing adequate heating for the space it serves.
