1. 2

2. 4

3. 6

4. 8

The correct answer is: 8

The B149.1-05 code, which pertains to the installation codes for natural gas and propane appliances in Canada, outlines the importance of proper venting and air supply to ensure safe operation. These requirements are essential for preventing issues such as backdrafting, where flue gases may enter living spaces, or improper combustion due to lack of sufficient air supply. The section of the code that deals specifically with venting and air supply is found in Section 8. This section details the necessary guidelines for vent systems, including types of venting, installation requirements, and specifications for combustion air supply. Ensuring compliance with these guidelines is crucial for maintaining safe operating conditions and minimizing the risk of accidents related to gas appliances. In contrast, other sections of the code, such as those related to general installation requirements or specific appliance installation procedures, do not focus as directly on the critical aspects of venting and air supply. Therefore, Section 8 is recognized as the authoritative source of information on these vital topics within the B149.1-05 code.
