Question

TH 36 Trueheat
Dear James,

I am attaching a picture of my fireplace which is original from the time our house was built, we are the third owners. I know that this is a TRUEHEAT TH36 Fireplace. We are currently not using the unit, have removed the glass doors, and tiled over the existing brick.  It seems like this unit was designed to incorporate a gas burning log and blower system. As a result there are large vented cavities on either side of the fireplace opening as well as above and below. This allows quite a draft during the winter months since the unit sits in a vinyl sided Chimney that is cantilevered over dirt. We will eventually convert to a ventless gas-burning log, but the cavities will still be there providing a cold air draft while it is not in use. How would you recommend reducing/eliminating the draft both now and in the future?   Thanks   Mike  

Answer
Hello Mike, when building that "chase" over the dirt they did not insulate the outer walls, so air will get in. before you do the logs you should check the owners manual (If you have it I would love a copy)it might be time to remove this fireplace and install a direct vent gas fireplace and install it correctly, check your local wood/gas stove store and see what they have.

    CommentThanks James, Not necessarily what I wanted to hear - just logs would be cheaper -but it answers the questions regarding what can safely be done with the existing unit to reduce the draft. I get in touch with a local expert regarding putting in a unit. Thanks again. Mike
