We have a timtex prefab fireplace in the house that we bought a year ago. Recently we pulled out the wood burning insert and want to use it as a regular fireplace. We discovered that there is no damper, looks like it was never installed.

We have called all over and tried to come up with a solution but nothing. It's tough since the company is out of business. Anyone have any idea where I could find a damper for this fireplace. It is a TBF36-2RS.

Also, are there any other solutions aside from adding glass doors? That looks like our only option at this point.
