I’m an architect in Cincinnati, Ohio and have a problem I’m trying to resolve for a client. Their new home includes a large (as in 65″ wide by 50″ high) fireplace in a big central hall. The fireplace uses gas logs, has no doors or sealed enclosure, and an 8″ flue. The box is a concrete composite made by a company called Firecast out of Canada. The flue is as they recommended, but as one might suspect, we’re having a tough time getting enough draw to actually get the gasses produced by the logs up into the chimney. The chimney is plenty tall (about 30′), and the contractor even added a booster fan (300 c.f.m.) in the chimney, but we’re still not getting very good results. The client would prefer to not have to enclose or hood the opening. Any suggestions?
