Should I screw each section of stack pipe, rivet each section, or only worry about securing each section of pipe that extends above the roof? It's stainless stack pipe if it makes a difference. Thanks! Ted

I would use stainless screws. It’s how we did ours and if you need to take it apart is easier then rivets to take apart.
Thanks Paul VT. Stainless sheet metal screws?
Yup. Any hardware store will have them.
You may find it hard to drill a hole in SS unless you use a cobalt drill bit, others dull very quickly in SS. Pick the bit that is the diameter of the screw shank not the threads. Cobalt is far better than cobalt coated.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
Thanks for the replies. Another question: can I use regular caulk under and around the roof jack or is there something special (high temp) i should use? Ted
Hey Ted: if your worried about heat migrating to the caulking joint on the jack check out this stuff Z-Vent Sealant we used it for medium temp joints on things like stainless "B" vent chimney it sticks like crazy to clean metal and stands up to heat well. Jay

Thanks Zucker Lager, I'll check it out. Ted
Drilling holes in stainless sheet requires 4 things.
1- A sharp bit (I often use a step bit
2- Tapping or cutting lubricant
3- Steady-firm pressure
4 ..And most important...Low RPMs.. Run the bit too fast and you'll just burn it up.
Dip the bit into some tapping lube, start with it just barely turning, keep the pressure on it, slowly increase rpms and you'll soon see chips or a spiral of stainless. Hold that bit speed and you'll be good.
