Due to temperature issues, I’m moving my whole Forge operation to a basement room, forcing me to rethink the venting plan. (no, I haven’t even plugged my Forge in yet; don’t get me started…) Long term, I’ll be running a real vent through the wall, but for now I want to just do it through one of the windows. These are basement well-windows (I’m sure there’s a real name) with the wells capped with clear plastic rain-caps, a necessity (kind of looks like a half-igloo).
So the plan is a little more complicated than just pulling out the window and replacing with a (short term) sheet of plywood or (medium term) plexiglass with a 4" hole and the vent connecting through that. That’s all well covered in other posts.
What I’m noodling is the well-cap. Again, I need it or rain will definitely pool in the window well (bad). So two options I see: #1, ignore it and just vent right into the covered well. I seriously doubt it’s airtight… but I really am uncomfortable with the idea of filling that little space with exhaust. I also suspect I’d get back pressure on the line to some extent, limiting the effectiveness of the venting.
#2 is to cut a hole in the cap and run the vent through it, vertically up a little ways, and then end it with a right angle and one of the standard vent hoods to keep water out. I can secure the vertical run to the house wall, and would have no worries for back pressure etc. The trick is that the cap is basically a quarter-sphere of somewhat flimsy clear plastic, and so cutting the hole for the venting to run through and then sealing it against rain getting in the well has to be done right.
I’m leaning toward #2. But I’m very interested if anyone has done anything similar and has suggestions? And pictures?
