What defines high heat appliances?

The definition of high heat appliances is based on their combustion temperatures. Specifically, appliances that operate with combustion temperatures exceeding 2,000°F fall into this category. This high-temperature threshold is significant because it determines the materials that can be used for the construction and insulation of such appliances, as well as the safety measures needed to prevent fires and ensure proper ventilation.

High heat appliances require special consideration in design and installation due to the extreme temperatures involved. These temperatures can affect not only the appliance itself but also surrounding materials and components, necessitating specific guidelines laid out in the International Mechanical Code to ensure safe and effective operation.

While other temperature ranges indicated might define different types of appliances, they do not meet the criteria for high heat appliances as established in industry standards. Additionally, the claim that high heat appliances are used only in commercial settings is not accurate, as these appliances can also be found in residential applications, depending on the context and needs.
