What does the B149.1 Installation Code also cover?

Installation of electrical systems
Installation of venting systems
Installation of safety systems
Installation of drainage systems

The correct answer is: Installation of venting systems

The B149.1 Installation Code primarily focuses on the installation of gas-fired appliances and equipment. However, it also includes guidelines for the installation of venting systems that are essential for the safe operation of these gas appliances. Proper venting is critical to ensure that combustion by-products are safely expelled outside, preventing the build-up of harmful gases like carbon monoxide inside living spaces. This aspect is crucial for ensuring adequate air supply and maintaining safe pressure levels within the venting system. While the other choices pertain to areas of installation that may fall under other codes or standards, they are not covered by B149.1. The importance of venting systems is emphasized in the code to ensure compliance with safety standards and to protect the health of occupants in buildings using gas appliances.
