We live in an older home which has a fireplace that was originally wood-burning but had a pellet insert installed, since removed when we had geothermal heat installed. We love wood fires and are considering purchasing a Jotul Kennebec or Rockland wood insert, partly because the fireplace is beautiful stone with an arched opening and we were told we could have the unit recessed into the fireplace opening, keeping the existing stone arch. This requires installing trimmable steel surround, instead of the standard surround. I can't find any information on trimmable surround. 1. Does anyone know if there are any issues with having trimmable surround installed, and/or with final result? 2. One guy who is familiar with Jotul but not trimmable surround included 1 hour labour with his quote but said any additional would be on time & materials basis - is this reasonable? Thanks for any help..
