How to tie in a bathroom vent to a cookstove vent?

[timmyg123]

The bathroom pipe is 3"

The stove pipe is 6" and comes down in an elbow.

The 3" is heading straight toward outside of elbow of 6"

How do I put the 3" into the 6"?

I assume I need some sort of valve so the
bathroom air doesn't go up toward the kitchen
and the kitchen fumes don't go toward the bath?

If you check with code you cant do that. Also you dont want to do it. Vent the bath out the roof or the over hang.

I don't think I have much choice. it's 30+ feet to wall
with siding, this fan is right next to wall with brick.
It's already running 20 feet with a couple bends to
the stove vent.

If I go against code, how would it be done?

You just can get a 3" pipe into the outside bend of a 6" L90o. The air bloweing up will stop the air from the bath and would try to go out the 3" pipe. It wont work

So get a 6" L 90o lay out a 3" circle center on the first section. Cut it out. Now get a small piece of 3" pipe cut up on the edge about 1/2" every 1/2". Bend every other tab out 90o put into the hole and bend the tabs inside over 90o and yoou have it made

God luck :wall:
