What to do when a Lyemance damper is a good option, but the opening is a bit too large.....

and you like metal fabrication.

I got it done this weekend, and it looks great!  Thanks for your help. Kevin L Hastings, NE

This custom welded steel "box" made it possible to install a 13x13 Lyemance original damper to a larger liner-less brick flue opening.

*NOTE:  The fireplace was tested to draft with a smaller flue opening to be sure that the Lyemance damper would cause no restrictions or smoke issues.

The use of a Lyemance damper in this installation was that of the home owner/installer.  The "cap-less" design and low profile of the damper were wanted and pleasing features.

Another alternative would have been the Chim-a-lator. These are at: http://www.chimalators.com
