Found a regency I1200 for practically nothing. Home owners bought the house and it was just set in the chimney and never used. It had no flu liner hooked up or anything. The new owner wants a open fireplace and wants it out of the way. I plan on getting a liner from chimney liner depot "flex king 6 in". I have never installed a insert but it does not look that difficult. Cut the damper out, put the liner down and hook up and install the cap. Im sure their is a little more but i think i can handle it. If any one has any input before I start the install let me know.
