What types of appliances are typically covered under G1 certification?

G1 certification primarily covers residential appliances that involve the use of gas. This includes residential furnaces, which are essential for heating homes, water heaters that provide hot water for domestic use, and ranges that are common cooking appliances in households. The focus of the G1 certification is to ensure that technicians are adequately trained to safely install, maintain, and repair these types of appliances in a residential setting.

The certification is geared towards ensuring safe and efficient operation of these appliances, which involve potential hazards such as gas leaks or improper venting. Understanding the unique features and requirements for installation and maintenance of residential systems is crucial for safety and compliance with regulations.

In contrast, industrial boilers and furnaces, commercial ovens and stoves, and portable space heaters fall outside the scope of what G1 certification typically encompasses. These appliances require specialized training beyond the residential focus of G1 certification, often needing additional credentials that pertain to commercial or industrial standards and practices.
