Wood stove pipe size VS draft

[ultrarunner]

I’ve seen wood stoves installed with the stove pipe to my mind reversed….

Instead of the lower slipping into the upper the lower slips over the upper.

I asked the sweep and he said it prevent liquid running down the inside of a section of pipe to daylight.

I then asked about smoke getting out and he said it won’t and that is the magic of draft…

That is the correct way to install from everything I've read. Male end points toward the wood stove.

yeah its all about keeping the creosote inside the pipe if not it leaks outside, drips on the pipe, on the floor and it is stinky/messy.

Backpuff on a stove is something that can happen. Snuff the fire too quickly, unburned fuel accumulates, when it does get air it can let off a flash of flame in the firebox and flue, and put momentary pressure in the pipe and stove instead of a vacuum. It did that once here, and the whole works looked like a cartoon with smoke blowing out of every orifice, ones you wouldn't think should be there.

The orientation of the pipe section connections will not change this. ;-)

On the Duravent DVL double wall pipe I am in the process of installing the female end points towards the stove. And regardless, if you have creosote liquifying with enough volume to actually run out the bottom of the pipe you are doing something way more wrong than having your pipes in the wrong orientation. Larry said it best above...

People who burn wet wood should not burn wood.

Tell me about that "wrongness" when it's 30 below, and the stove is running with all it's got just to keep the wife happy.

This was from two winters past, a cold snap...

Ouch!
Do you feel like your wood was seasoned adequate? Also maybe it has something with the horizontal section of pipe. The creosote that does accumulate runs to the bottom. Not sure.

it can happen very much with a stove that is over size for the area or when it is not very cold out and it runs choke even with dry wood and high ambient humidity and low atmospheric pressure it will generate creosote it might just be once or twice a year but every once in a while the stars aligned and it dose … I always make sure it is properly oriented because once it start leaking out it is not fun to turn around lol

There is seldom need to fire the stove hard enough to get the creosote running. But there is always "some" deposits in any flu pipe.

Heck, I cleaned the stuff out of the pellet stove pipe just before the weather turned. Yup, there was "some" build up even in there. (It's warned about in the operators information, so I don't take any blame for it. Creaosote JUST IS! ;-)
I've lived with it for over 40 years, and kind of like the aroma, Reminds me of a smoky Scotch/

Lagavulin anyone?
