I have a new, never used DESA vented gas/propane fireplace insert.

　　It comes with the logs still wrapped.

　　DESA went out of business several years ago so replacement parts are not available.

　　The insert is missing the upper louver panel.

　　You may be able to have something made that will work.

　　It is a 36" model - model # T36EP

　　Max output rating 15,600 Btu/h

　　Color is black

　　Call

　　and ask for Bob.
