I am an owner/builder, not HVAC professional, but I would appreciate help before I spend $$ to have it fixed (or maybe not).
About a week ago we had a furnace finally fired up. Keep in mind that the guy that did it, has his license only for about 1 year now. Bad thing is that I had little/no choice in choosing him. I can't catch this guy to fix it and retailer requires him to inspect the problem (or finish the install - return drywall cutouts, ect). We find out more and more of bad things he did during this install but it's not the time to bash anyone, just to find a solution to my problem.
It's a brand new Ducane furnace, upright, with side return.
You can see where the water leaks. I believe that long black box underneath exhaust fan is inducer assembly. When furnace runs, it doesn't leak. On the shutdown, when inducer motor stops to spin, water shows up in the bottom right corner.
We checked the furnace if it's plumb and level and corrected it a bit, which kinda slowed the leak process. But it still leaks.
1. What would be the most likely problem? Bad seal? Would high-temp silicone fix it?
2. Is that yellow cap on the right side of exhaust clamp supposed to be removed?
3. Drain pipe from furnace goes to a tee (which gets drain pipe from coil) and runs to the drain. Drain exit from the coil blows warm air when furnace runs. I did remove the coil part but it didn't make a difference in water leak. To properly run both in 1 drain, do I need just an extra vent T before coil drain pipe gets to the main T?
4. Manual said to prime the drain box. I did but it didn't make a difference for a leak.
Thanks for help!
