What is the maximum temperature for B vent?

The maximum temperature for B vent is 240 degrees Fahrenheit. B vent is commonly used for the venting of natural gas and propane appliances, particularly those that are categorized as vented appliances. The design of B vent is specifically intended to handle the needs of these systems, including the temperature of the exhaust gases produced during combustion.

The materials and construction of B vent are suitable for the temperatures typically encountered when venting gas appliances, which often do not exceed 240 degrees Fahrenheit. Knowing this upper limit is crucial for ensuring safe installation and operation, as exceeding this temperature can compromise the structural integrity of the vent and lead to hazardous conditions, such as vent failure or fire.

In contrast, other options represent temperatures that are generally outside the safety range specified for B vent systems. Understanding these limits helps HVAC professionals and installers to select the appropriate venting products for their specific applications, ensuring safety and compliance with code regulations.
