What is the maximum temperature of the combustion products for a low-heat, nonresidential appliance?

For low-heat, nonresidential appliances, the maximum temperature of the combustion products is generally established at 1,000 degrees Fahrenheit. This temperature limit is set to ensure safe operation and effective heat exchange without causing damage to the appliance or its components.

Appliances classified as low-heat typically include those that do not produce significant flue gas temperatures, which helps in maintaining efficient combustion while minimizing wear and tear. Understanding this maximum temperature is critical for compliance with safety standards and operational efficiency, as exceeding it could lead to risks such as equipment failure, increased emission of pollutants, or even fire hazards.

In contrast, the other temperature options represent thresholds that exceed the typical operating conditions for low-heat, nonresidential appliances. Therefore, the correct temperature understanding is essential for proper installation and maintenance of gas appliances.
