I'm installing a pellet stove insert in a masonry fireplace that is located in the center of my home (no access to an outside wall) and would like to add a outside air connection. I'm installing the exhaust flue (probably 4") inside of a 10 inch diameter SS re-lined chimney. Can I terminate the outside air connection inside of the chimney just above the damper blockoff plate, assuming that I run the exhaust flue all the way up the chimney to the cap (about 15 vertical feet)?
thanks in advance, snipped-for-privacy@verizon.net
