I came accross this HEIL Ultra Efficiency gas furnace yesterday and have a question about it. The pvc drain line runs accross the top and down the left side and the furnace is vented through the ceiling by pvc. When the drain goes accross the top it runs over an opening and has darkened the underside if the line. My question is first-what is that opening for and should be capped off or vented out or what? I told my client that he would need to run the drain around the opening anyway because the line is slightly sweld there and we run the risk of it leaking. I hadn’t seen anything like this and told him I would get back to him. I have tried to call all of the HEIL dealers around me but of course they are all out on calls. Any suggestions appreciated.
