Thanks for all the great information on wood stoves! I'm posting some pictures of my install to return the favor. My application is a masonry fireplace with full clay liner. Had it cleaned and inspected before the install. Stove is a Quadrafire Cumberland Gap. I decided to use the rear vent feature so I could exhaust through the existing fireplace. I extended the existing hearth by 24" to get the required clearances. My hearth extension is two pieces of flagstone floating on 1/2" Micore 300 mineral fiberboard. BTW I have a couple pieces of the Micore left if anyone near West Chester PA needs any. I got a stainless steel flexible chimney liner, insulation kit, and stove pipe from Chimney Liner Depot. I removed my fireplace damper plate and cut out a small section of the damper plate frame to let the liner pass through. Connected the tee and the tee cap to the flexible liner. I used some of the leftover Micore 300 to block off the damper opening around the liner. Then I added the snout and moved the stove into place. Moved the stove into its final position and made the connection to the stove pipe. Hope this helps someone!
