Which appliance type is characterized by combustion products entering the flue at temperatures more than 1,000°F but not exceeding 2,000°F?

The characteristics of appliance types are defined based on the temperature of the combustion products entering the flue. A medium heat appliance specifically refers to equipment with combustion product temperatures that range between 1,000°F and 2,000°F. This classification is important because it determines the type of materials and methods used in venting these appliances, which are necessary for safety and efficiency.

Understanding this classification helps professionals ensure compliance with the International Mechanical Code and maintain safe operating conditions. The venting requirements, materials, and installation procedures vary significantly according to the heat classification of the appliance, emphasizing the importance of identifying the correct category based on temperature ranges.

Other appliance types, such as low heat or high heat appliances, have different temperature ranges, and high-efficiency appliances focus more on energy savings rather than specific temperature characteristics. Thus, recognizing the medium heat appliance as one that operates within the specified temperature range is essential for proper venting design and implementation.
