Spigot Direction on stove pipe
[email protected]

On stove pipe installed for wood burning stoves, does the crimped spigot go up or down? A code reference would be greatly appreciated.
Thanks, Jigs.

In general, figure that crud will flow downhill. Put the smaller part into the bigger part so it doesn't leak.
Always point the crimped ends down. It sounds counter-intuitive from a smoke point of view, but that's not the issue, creosote (a liquid) is. As the smoke cools, especially if you're burning wet wood, creosote condenses on the walls of the chimney. When it runs downward you don't want an upward-facing lip to catch it.
This will not cause smoke to leak into the room, provided the pipes fit well.
BTW, it's nice to install a slip-joint section just above the stove to facilitate disconnecting the stove in case you need to move it for sweeping or any other reason.

I've always heard the crimped section is down ... to properly drain condensing material back to the stove rather than run out and soil the piping (or worse, catch fire during a hot flash in the flue).
