Chimney pipe orientation

[svk]

Just read that the male end of the pipe should face downward towards the stove as to prevent ash build up in the joints. I've always seen it done opposite around here. What say you guys?

Yup,male end down and inside of the female end (male ,female ,pretty obvious).I never worried about ash build up much but runny creosote dripping to the outside of the joint-not good!

Male down creosote can drip down in liquid state and will leak out the joints if you Mount it backwards

The leaky creosote then catches fire... on the outside of the chimney...
Very good question, as I too have seen some installed improperly, and important to get it right.

A funny thing when I bought the house the 3 wood burners required replacing so I did 2 an 8 & a 14 kw I replaced with models From the "Godin" range the 3rd the place of purchase was including fitting at an all in price so I let them do it The 2 I did the flue male spigot I fitted facing down the suppliied stove flue the male spigot is up I diddn't notice for a couple of weeks as the stainless flue pipe has double "joggled rings & the pipe end fits right up to the "joggle" when I went to ask him to change he told me that his was correct & mine not so & wouldn't change it. I asked the fire prevention officer at the fire station he came & looked & said mine were correct & said he would get the guy to change it I said I would do it myself so he said OK give me a shout & I'll come & look & issue the paperwork a couple of months ater I had reason to pass the stove guys shop & it was all shut up asking the fire guy it seems the stove guy had fitted a lot of flues incorrectly & had refused to change them so the fire officer closed him down

The video in post 6 the stove flue pipe have very crude pipe joints compared to the ones we use with the double "joggle"& dont require ST screws to hold them in position&the edge of the outer pipe fits very close to the joggle so doesn't leave an open edge. Very little black pipe is used it" almost all either Stainless or Ceramic coated

Way back when my neighbor asked about that. His pipe was filthy with black streaks. I told him his pipe was upside down. "aw BS". Some old stoves did have the outlet fixture as a male pointed up and one had to get a doublended female joint to get the pipe run going the right way.

Idk in the hvac world we always do the male end up because that's the direction of flow. On a draft induced system it could push the flue gas out the crimp if the female end is up. With the male end pointing up that's not really possible. We also run the pipe seam down on flue pipe for the same reason the hot gasses will be at the top of the pipe.

I guess on a natural draft running it upside down wouldn't make it back draft out of the pipe but it still seems wrong to me.
