chimney installation? before or after ceiling installation

[bergw]

I'm trying to work out the best time to call in the installers for my workshop.

The framing is complete, and it's 100% dried in.


Is it easier or better for the installers to handle the chimney/woodstove install before or after the ceiling and insulation goes up? (1/2" pine panels).

I won't be firing the stove until the ceiling is in. this is because of the ventilation system, i fear it'll cause huge draft problems, but i'd like to make this as easy as possible,
and it doesn't really matter to me when i start nailing the boards in.

I would install everything from the ceiling support box up now, and then the rest after everything is finished. Make sure to have an insulation shield installed and check everything out after ceiling insulation is finished to ensure someone didn't leave anything leaning against the pipe.
