I started off with removing the old condensate drain line. I replaced the hose adapter that sits in the bottom of the humidifier box. Next I ran the drain line. I used a copper hose clamp to secure it and to pitch the drainage. I ran some water through the line to make sure there was no leaks and that it flowed correctly. Lastly, I reconnected the humidifier and turned on the furnace.
