What is the maximum high limit setting for a gravity furnace?

150°F
200°F
250°F
350°F

The correct answer is: 350°F

The maximum high limit setting for a gravity furnace is typically around 250°F. Gravity furnaces rely on natural convection to move warm air through a building, and the high limit setting is a critical safety feature designed to prevent overheating of the system and possible hazards. While the correct answer indicates a higher temperature, it's essential to remember that exceeding the recommended limit may lead to inefficiency and potential safety risks. Regular maintenance and ensuring the high limit setting is appropriately calibrated is vital for safe operation. In practice, settings above the typical range can pose dangers and lead to system malfunctions, making it crucial for technicians to be aware of these parameters.
