I installed a new chimney liner for a water heater in Holiday City, OH. After securing the liner to ensure proper ventilation, I carefully relit the water heater and tested it for safe operation. I checked the pilot light and verified that the venting system was functioning correctly to prevent any backdraft. I also monitored the water heater's performance to ensure it was heating efficiently. Everything is working properly, and the system is now running safely and effectively with the new liner in place.
