Im trying to meet min. Clearance for a freedom insert. My fireplace is in the corner with brick facing. I have 13" from the brick facing and 17" from the drywall. My understanding from the specs is i will need 15" from the bricks. I was thinking of removing the brick facing to gain the space i need. To remove brick and leave just drywall seems counterproductive to me but i guess it is all in the spacing. Does anyone have a suggestion or idea? I was also thinking of off centering the insert to gain the clearance. What do you think?
