Stove Pipe Direction

Which is the proper way to point the stovepipe....male end towards the stove or away from the stove?

Crimped end to stove(male)

Yup, that's old school & been working for many, many years. More importantly, it's the way I do it.

so that if rain water runs down pipe,it won't seep thru pipe joint

That's why they make caps. As for the seams, notice the lil lip right above the male crimping.

whats the lip for?

Male end goes away from stove when buring coal

Male end goes away from stove when buring coal

Here we go!

I was taught male down, but thinking about coal and having no moisture running down the pipe, I can see that it might make no difference. Just if anything comes down the pipe, male down will keep it in the pipe easier. Draft wise, it makes no difference. Most guys seal the joints and then put a great big hole called a Barometric in it.

OK, I'll settle it. For wood, male end down, for coal male end up. It doesn't matter how someone was taught or how they've always done it. This is the correct way.

Just waiting for the acerbic Sting to weigh in!

Mine are male end toward the furnace outlet, only because thats the end that fit when I started assembling the pipe lol. I think this is the proper way for wood, so when condensation from moisture in the wood forms on the inside of the pipe, it won't seep out and run down the outside of the pipe which would make a huge ugly mess...

I don't know why you would need the male end the other way for coal.. As long as you maintain negative pressure in the pipe and seal the joints with high temp silicone or foil tape there shouldn't be any danger for leaking carbon monoxide. Hopefully somebody with more knowledge about this issue will chime in

I'm gonna take a stab at it and say its so rain can't run into the pipe joints, mix with fly ash and creat sulfuric acid to eat the pipe up lol. But, stove pipe shouldn't be exposed to the outside anyways hahaha...

For coal any way you want it, or sometimes the only way it will fit.

That's how my stove is.

My opinion is to have the stovepipe male end pointed towards the chimney thimble. Why? When there's a coal gas puff back or explosion having the male/female connection in this way will direct the expanding gases to the chimney rather than having some get caught in the connection joint if the pipe is reversed. Admittedly it a small benefit but that's what I do.

I've not burned wood, so I have no practical experience, but I don't understand the male end towards the stove recommendation. Yes, I understand the water or liquid comes from flue gas condensation. But wouldn't that occur in the colder chimney stack and just fall down to the chimney cleanout? I would expect and short stovepipe from the appliance to the chimney thimble to be two hot for condensation to occur.

No Yanche, that is not always the case. And some people run long lengths of pipe to squeeze all the heat out. My business partner had 28+ ft. runs straight up and the condensate ran right down to the elbows and dripped on the floor. A chimney does the same thing and I have seen it run out of the bottom either through the clean out door or under the first course of brick or block. A cap helps but does not prevent the whole issue.
