Hello, am looking to get some information here on how to hook up a wood stove to an existing masonry chimney. In recent years, the home was heated with a fuel oil furnace in the basement of a 3 level home. The fuel furnace is broken and I have chosen to switch to wood heat for this year. I would like to install a Fisher Grandpa bear in my house on the main level. See attached pictures the chimney is located between the blue doors. Also need to know the best location of the hole, do I run horizontal from the rear of the stove into the wall or do I put some elbows in and go farther up the wall to enter the chimney. Any feedback would be appreciated mainly wanted to know if you think this would work for installation and how to cut a hole in the chimney and any other details that I may have missed. thanks.
