    I had a smoke hood built at a sheet metal shop and I am in the process of installing it above my eko. I really can't go out the roof because of space and need to go through the wall. I can find 8" wall vent caps for dryers and range hoods but I am concerned that they would cause the siding on my building to get stained from soot. They direct the smoke down and not out and up. I also need a backdraft flap built into it. Any ideas?

    Reduce to 6" before you go out - to give you more options?

    My old cobbled one was just 6", seemed to be lots.

    I don't think you're going to have soot/stain issues with a smoke "hood". You're not going to be venting that much smoke, at least I wouldn't think.

    I have my "exhaust vent" vented through a louvered cap that directs the air down along a section of siding on the back of my house. I only run my blower once in a while when I know I'm loading at a bad time but I've never had any staining issues.

    I use a 4" in-line "Hurricane Fan". Rating on the side says 200cfm. I vented to the outside with a 4" fully stainless steel dryer vent kit. Vent kit has a damper built in. Seal the seams with foil tape. It will suck a piece of paper through the opening in my hood.

    Haven't used it yet for reloading but it works well for venting soldering fumes!
