What do B149.1 and B149.2 installation codes cover?

The B149.1 and B149.2 codes are crucial components of the Canadian Standards Association (CSA) guidelines, focusing on specific aspects of gas installations. B149.1 pertains to the installation of natural gas and propane appliances, but it also encompasses details about venting systems, ensuring they are appropriately designed and installed for safety and efficiency. Venting systems are a vital part of gas installations as they facilitate the safe removal of combustion gases from appliances, which is essential to prevent hazards.

On the other hand, B149.2 primarily deals with the installation of various gas piping systems. While the codes are interconnected and often refer to the safe installation practices for appliances and the necessary accompanying infrastructure, the answer regarding venting systems aligns with the specific code provisions emphasizing how these systems must be managed during installation to ensure proper operation and safety in gas applications.
