Anyone know if this is possible or allowable and how it should be done? Customer of mine has a wood fireplace that he wants installed in his basement. But because it's not going in a chase I was thinking it could somehow get connected to a Class A wall outlet.
Having a difficult time getting a hold of the tech department of the manufacturer, rather not say who it is. Any feedback appreciated thanks guys.
 
Check the manual. It may not be allowable. Most, if not all, ZC fireplaces require a straight-up flue or close to it. Using stovepipe to connect a fireplace is also out of the question for any ZC I know of.
 
Yea there's no way I'm putting stovepipe behind a wall. And the fireplace came setup for chimney liner it looked like - there's some screws on the top already where I'd put an anchor plate, confused me. The manual isn't very helpful. Do you think insulated chimney liner might be an option? Doesn't seem to be anything I can do with Class A without a 90.
Pretty sure I'll have to tell the customer he's gotta put a freestanding stove down there just wanted to double check.

Without seeing the manual I can't say for sure but I seriously doubt it's possible. I have never seen a zc fireplace that allows this at all
 
Proceed with caution if the customer concedes but wants a freestander in an alcove with a mantel for a fireplace look. Magazine (and now AI) images show this and it's a popular look in the UK. Alcove installations of woodstoves have strict rules. It can be done though it usually requires the alcove and mantel to be made of entirely non-combustible construction. The second caveat is draft. Some basements are negative pressure zones due to competing appliances and exhaust fans including radon fans. It's a shame to see this when the homeowner has spent thousands for an installation that doesn't draft properly. Adding two 90º turns in the smoke path and a cold exterior chimney doesn't help.
 
Agreed. I didn't want to install a wall connection for the guy on a false premise that the fireplace could definitely get hooked up to it. Fortunately he's ok with everything. Thanks for the help.
