Slant fin rough measurements

I have the piping all roughed. I'm gonna be combining 3 6 foot and one 4 foot slant fins for a total of 1 22 foot baseboard run. Now that I'm about to drywall what is the exact measurements I need to cut holes in the drywall for the pex piping to stick out? Would it be 22 feet or do I make it a little shorter?

You using the FineLine 30 ?

Mike, I think he's looking for the 'end to end' dimension.

Correct fineline30. Yea in looking for end to end dimensions so I know where I have to get the pex pipe through when I put up the drywall.

I looked for CAD drawings that give the dimensions and didn't find any. Find it strange that they don't give that, or it's not easily found.

Presume that the 22' is one straight run along one wall? Is the enclosure going wall to wall?

Make sure whatever you do that you leave room for expansion.

It's one run along the wall but won't take up the whole wall. There's like 1 foot to spare.

22ft then the pipe should 22ft apart.. From inside to inside edge on pipe...End caps will make up any screw ups...

But what about the elbows Mike? They add a little...

And are you certain that the pipe in an 8' element is exactly 8' ?

What happens then when the two pieces are put together? How long is the fitting on the end of the element? So two 8' elements then is slightly less than 16' ... then add another 6' element, slightly less than 22'... I THINK that the fittings are 3/4" long so the total length of the 3 together is an inch and a half less than 22'.

But then remember that one end has the swaged end... and you also need to know the dimensions of your PEX to copper adapters.

That's what I was wondering, when I put the 3 together does that change the length of it making it shorter than 22ft? When they connect to each other is a coupling used or do they just fit into each other? What about elbows?

One end of the element is normal pipe, the other end is 'swaged' so that the next element slides into it. You don't need couplers. I believe the length of the swage is 3/4" so you would subtract that each time you put two sections together.

Yes, what about the elbows, and how are you planning on connecting the PEX to the copper?

I'll attach the pex to copper the same way the builders did it when they built my house. They sell elbows pex to copper. So I should probably go 3-4 inches shorter than 22 ft from inside pex to other inside pex? I guess I could just pull the baseboards all out of the box and piece them together n measure before they drywall but that would be a hassle. And if I fit them into each other can I take them back apart?

Took out the baseboards and connected them all here are some numbers.
The actual length of the baseboard that gets nailed to the wall is 264 and a quarter inches. The size of all the piping connected is 3 inches less so 261 and a quarter inches. That's not counting the 3/4 of an inch on one end of the piping for a fitting or elbow to fit into. So I have about 1.5 inches to fill on each side (not sure if elbows will be enough to fill those gaps. So should I pull the pex through at 264 and a half from inside of pex to inside of pex? Or should I make it a little longer than 264 and fill the space with copper pipe?

I am trying to tell you. You pipe to the BB covers. 22 ft apart inside pipe to inside pipe.. The element is always shorter. When you reach the other end of the element its usually a coupling and a short piece of pipe..

You dont want shorter then 22 or you will need to cut the covers.. And who wants to do that...!!!
