Preferred Pipe Joint Direction

Re-doing the pipe on my hitzer 50-93. I have decided I want the crimped end of each pipe to be installed away from the stove outlet however the outlet on the Hitzer will only accept a crimped end. An elbow needs to be in the stove outlet. I have 2 elbows and neither of them will fit the outlet using the plain or un crimped end. I have used a die grinder to chamfer the inside front edge of the outlet to eliminate any burrs.
Bottom line does assembly direction matter? My way of thinking is with the corrugated edge facing the flow of gasses they could possibly pass along the corrugating slots and leak out. Also the corrugated end could reduce flow when it faces into the flow direction.

DW, here ya got 6 of one, 1/2 dozen of the other. I've put mine down goin on 10 yrs with never a problem--just screw joints no matter which way.

Crimped end down is a holdover from wood burning. Creosote stayed in the pipe rather than running down the outside. With coal either way makes no difference. When assembled tightly the joints seal unless as sometimes happens the pipe is badly made, in which case just use a little furnace cement to seal. The corrugations probably do reduce flow a bit but I think so miniscule an amount that it would be very hard to measure.

Screws for sure.........3 to a joint.

Foil tape.

Screws!!!!! Lots easier to replace when needed.

The above posts are all good points. Like Fred said, In my mind it doesn't make any difference. My choice would be to keep it crimped end toward the stove like franco said in case condensation or rain water ran down the inside of the pipe. It makes a hell of a mess if it can get out thru a pipe joint, true story

Also, keep in mind that as long as there is ANY negative pressure in the pipe (and there always is unless there is a draft failure) exhaust will not be able to escape the joint no matter what direction its pointing.

Foil tape like mozz suggested will help keep your piece of mind and can even help make for better drafting, I use it too.

Don't fret over it too much..

Yup, I gave up fussin over it. What you see is what I got Tape might be a good idea, but two things I don't do well are saran wrap and any kind of tape. Wrinkles, crooked, you name it!
If Hitzer designed it this way who am I to argue?

Here it is, it's called a starter joint.

You could also get a crimping tool.

Indeed DW. Looks REAL good, safe & functional.

If the device can burn wood put the male end down. Sooner or later someone will burn wood in it.

That's what he did CS. Coal or wood.

Like others have said; It'd work either way. I prefer crimped ends facing the stove for same reasons lightning said. Water/condensation will make a mess. Oliver

Wait a minute, you guys saying it's better to let the water run all the way down into the stove body where it can NOT be seen other wise it will cause a mess on the pipe showing above the stove.

Dang, bet that's not a happy surprise when it gets discovered inside the stove after some months.

No condensation when the stoves out & it'll evaporate before it gets to the body when it's going.
