Throughout this course, we will explore the Furrion and Girard tankless water heaters, the two options offered by Lippert. Through a range of mockups, participants will gain insight into the correct installation and operation of their water heaters. Additionally, hands-on experience at various stations will be provided to troubleshoot different error codes, understand their significance, and learn how to resolve them. Proper maintenance, winterization, and descaling procedures will also be discussed.
