    retrofit gas insert that is see through

    I have a gas burning fireplace built in about 1978. It can be wood burning or gas, (masonry construction) but it was fitted with gas logs and looks to have never been used for wood. It is a "see through" fireplace, open on front and back. We would like to put an insert in that is direct vent, but the handful of local (Chicago area) companies we have contacted indicate that there are no "see through" inserts. (Or that you cannot retrofit a fireplace with a see through insert without opening up the chimney, etc)

    We would like the fireplace to be more efficient, but more importantly, we would like to use outside air for combustion. Is an insert the only way to do this? Are we stuck with what we have? help!

    There are no efficient see-through inserts. The only way to get efficiency is to put in a normal single sided insert on one side.

    Cool

    From a mfrs perspective, there is no way to make an insert that is adjustable in depth as a ST so one size could never fit all. You only option as I see it is to close off one side to where it meets the code as a single sided fireplace then install ONE DV insert on the side or choice. Doing two inserts back to back is not recognized but your AHJ may sign off on it. With a stone facing, you might have enough depth.
