How do I remove a BIS Traditional Zero Clearance?

[Ben311]

I am demoing to remove some rotted framing around and below my zero clearance fp. (https://www.hearth.com/talk/threads/iding-type-of-fireplace-and-potential-insulation-issues.182769/).

I need some help determining how to detach the unit so I can pull it out, as allowing me access to replace the rotting plywood and framing below. I can't for the life of me figure out how to detach it. The manual (https://www.google.com/url?sa=t&sou...FjAAegQIAhAB&usg=AOvVaw0oMYq0WcFpdLnGWcfqtugs) states that there are four mailing flanges to secure it to the floor. I don't see any. I can remove the heat ducts with a counterclockwise turn, but not the chimney pipe itself. Any ideas? Thanks!

Is unit replacement your intent? Or repair/reinstall? It seems it is a rather old unit. Might be the time to investigate option's? Tough season for diving into this project! God speed

My intention was to just reinstall this unit, so I would like to remove it an keep it intact. Thanks

Start by downloading the manual. That will show the order of installation that needs to be reversed.

Thanks. I did, but it doesn't detail how the chimney connects to the unit (and hence how to disconnect). I am probably overthinking it, and just need to be a bit more forceful with turning the pipe. I suppose it isn't attached to the framing/flooring any other way.

Typically the unit is screwed to the framing studs. The pipe is attached to an anchor plate that’s brand specific. Often times the pipe is screwed to the anchor plate to prevent it from turning as the rest of the pipe is installed.
