Simple question. Why? I have a masonry fireplace, solid brick. I intend to build a solid steel damper/venting block at the elbow where it moves up into the chimney, and at the top to lock the chimney in place. Chimney=SS liner, Yes Elk, doublewall insulated. <grin> I like the looks of the fireplace. Why put surround panels on? Are they cosmetic, or is there a reason for them? I'm also thinking about an outside air pipe. Just musing. I think I've settled on what I want. I'm probably going to buy a Pacific Energy Summit Insert, nickel door and trim, and later down the road, a Snowflame 4100 corn fireplace insert. Between the two, I should be able to keep the whole house warm for a lot less money than the thrice be damned old oil boiler in the basement. Joshua "Censored" Apparently I piss people off. Sorry.
