This is a before picture, the wall was removed to expose the chimney.  This client has a chimney containing three flues, one of which is used to vent her heating appliance, the other two are inert.  Dana will turn this into a raised hearth, wood burning fireplace with stone veneer.  It will vent into the two inert flues which are clay tile lined.  Dana is using the two flues in order to create a taller, wider fireplace.  Please check back here to see the progress on this project.  For other fireplace/firebox construction and restoration projects http://www.dmstorrschimney.com/our-soot-stories/firebox-reconstruction-reading, you may also check under the Firebox Construction category on Our Soot Stories Blog.
