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,
