We have a brownstone in Cobble Hill and want to install new flexible stainless steel chimney liners on two of the four fireplaces we have in the front of the house. We will have two additional flues that will be vacant, unused probably since the 1960′s, when they were covered. In one of them we would like to have an insert, with intake fresh air from the outside, to make it more efficient and avoid consuming heated air from the house.

Anybody has ever used one of these unused flues to actually bring fresh air, using one of the Fresh Air Inlet Kits for Fireplaces?

I do not see any problem doing that since the two working fireplaces will be completely sealed with the new liners and there is no chance to get any fumes from the two working fireplaces.

On the other fireplace, the one that won’t be a cast iron insert, we want to use a Rumford fireplace. We would also like to have a fresh air intake in this fireplace.

The photograph is from a renovation posted on the Brownstoner some time ago.

I would appreciate any educated opinion on the subject.
