Hi gt390 thanks for taking an interest in my project. I chose PVC drain pipe simply because that's what the fellow whose project I copied used. I haven't noticed any strange smells after the first week of operation. Now it just smells like warm wood.

It's a Nutone ILF120 rated at 110 CFM. It's meant for 4" ducting. A 6" fan and ducting would be WAY better.

I do have one just like you describe on the inlet. It didn't stop bubbles of cold air from falling from the collector into the house through the outlet though, hence the funny looking foam door.
When I do this again, I will mount the collector to the wall against the house instead of being freestanding. That way I would not have airspeed losses or heat lost through the ducting. Plus more insulation on the wall.
