Deck ledger installation

In the process of installing a new deck, 40ft x14ft. I plan to install the 40ft 2x10 PT ledger board (multiple 2x10 board lengths) to the house, and not sure if the crown should be installed "UP" or "DOWN"?

I would go crown up since your joists will also be oriented that way, but I think it's mostly a moot point. You hopefully picked ledger boards that are mostly straight. You're going to be fastening them to existing structure with lag screws located along the length of the board, before any load is put on them. Thus the board will not have the opportunity to deflect--the main reason for going crown UP on joists.

crown up always. but where your talking about the ledger find the straightest wood in the pile for the ledger. it should get anchored every 32 " max which eliminate deflection..

its harder to put a badly crowned ledger on than it is to do with something thats straight. with the latter you just tack it to the level chalk line then bolt it on

And it needs to be flashed if it's attched to the rim joist of the house.
I space my ledgers out with 1 X 6 vinly lumber sitting vertical as shims so the water can not lay there and rot out the ledgers.

Or go steel and you won't have to think about crown.
