so I moved to a house a year ago with a night watch insert with a jammer install. I bought a liner kit and plan to install it in the next week or two. Problem is, I can’t figure out how to remove the surround to clean around the insert. See pics, the bolts in the pic just spun. Anyone know how to remove the surround or does it have to slide out with the entire insert? I installed a Vermont castings insert at our last house and the surround installed AFTER the insert was put in the fireplace. Any help or tips would be appreciated.
