You should find a new burner tech that knows how to set one up. Also explain to me the situations that it wouldn't work and your expertise on this subject if you want to call me out on it.

I had one on my MKII so I was guilty.
Here is why.
From NFPA 211 (the older free version, the new version may not have this phrase)
12.4.5 Connection to Masonry Fireplaces.
18.104.22.168 A natural draft solid fuel-burning appliance such as a stove or insert shall be permitted to use a masonry fireplace flue where the following conditions are met:
(7) Means shall be provided to prevent dilution of combustion products in the chimney flue with air from the habitable space.

Yes, but the baro is controlled air and will close if draft is low.
scalabro wrote:Yes, but they are NOT airtight, thus they can still leak either room air into the flue or much worse cause combustion gasses to leak into a living area.
It's my belief a strict inspector or zealous insurance claims adjuster would hang you on it.
