installation of Mark I in existing chimney

Hi guys,

I'm ready to start thinking about installing the new to me Mark 1 I was blessed with last spring. I looked up in the chimney yesterday. The flu has a 4 inch opening, the stove 6 inch. I know I can remove the flu and get a steel plate with a 6 inch hole manufactured to replace it. If doing this I'd just run black pipe from the stove up through the hole up the chimney about 5 to 6 feet blocking any openings with "rockwall" fiber insulation

But... I was thinking - could I get a simple 6 inch thimble and fasten it to the chimney walls with steel straps or other bracket. I could run one 4 or 5 ft section of pipe from the thimble up the chimney and block off any open space with the "rockwall" fiber insulation. Then I could just use a section of regular black pipe from the stove to the thimble just like I do with my other stove and its steel chimney.

I'm open for ideas. Thanks, Lisa

Lisa, are we talking a masonry stack, w/ fireplace opening? I assume by flue you mean the vestal damper forms a 4"x ?? rectangle when open inside the throat of the fireplace. Based on your description, I'm not really getting a clear pic of what you're dealing with and what you want to do. If possible (usually is) I would recommend cutting in a thimble above the fireplace mantle and setting the stove in front of the fireplace, this gives you an excellent connection that's easy to clean, easy to revert to original fireplace, looks neat, and works great; the main downside is the stove would be further into the room than if it were inside the fireplace itself.

You could also get a 6" round to oval adapter to pass through the damper throat. Put a T on the bottom for a baro and a cap on the bottom for a cleanout. Stuff insulation around oval on both sides to seal the rest of the opening.

Any chance for a photo? I know...it's dark & upside down. By "flu" you mean damper? I guess....if that can lift out & a round to rectangle adapter made, I think I'd lean that way. One thing to give thought to.... you know how we always screw the stove pipes together so a puff back will not make them come apart? How will it be secured?

Thanks for the replies - I'll try to get some pictures this afternoon. Yes when I said flu I meant damper. Cutting an upper opening for the thimble won't work. We'd lose half the room to the stove. By using the existing chimney and taking the legs off the stove we can fit half the Mark 1 in the firebox and not have to add to the hearth or take space from the room. Thanks again, Lisa

Thanks for the input - this project is on hold while we wait to see how the government shutdown is going to last. Thankfully, this is a nice to have, not a necessary project. Take care, Lisa

Hi everyone,

I'm moving forward on this. I stuck my vacuum up the firebox and cleared out the spiders but the flash on my camera doesn't work so no pictures. Sorry . The damper is a 4 inch by 24 inch rectangle. It will be no problem to remove the damper flap and use an oval adapter to get the black pipe through to the chimney just at Terry suggested. As for securing it, I was thinking of using metal straps like they use to hang venting in new construction. I am thinking I could secured the straps with screws into the metal frame of the damper. I would connect the sections of the black pipe with screws and slide it in as a unit. Then I'd push the stove in and connect the pipes and use 3 screws to secure them. That's my idea anyway. I'm open to any and all input. Thanks, Lisa
