I have a prefabed fireplace that can be either gas (current setup) or wood. I'd like to convert it to wood (gas assist), but am being told that I've got a severe downdraft, and would either need a chimney extension or a chimney fan.
Right now, the chimney extends ~4-5' above the roof, but is adjacent to a wall (I live in a converted factory, the fireplace is part of a one-story part of the house, adjacent to a 2-story part). Extending it to fit the 10' / 2' rule would mean something like a 10' vertical extension, which is probably expensive. Chimney fans are ridiculously expensive too (cheapest I've seen online is $1K, contractor quoted me $2.2K).
Are there other options?
