Installing a new dishwasher, and the elbow fitting that connects the hot water hose to the dishwasher ends up facing the wrong direction when tightened as far as it will go by hand. How many more times should I turn it with a wrench?

I'm installing a new Bosch dishwasher to replace our old leaky one, and I'm feeling good about all of it except for this one part. The 90 degree fitting which connects the hot water line to the dishwasher only turns about 2 times around when screwed in by hand, and then ends up facing the wrong direction for the water hose. It needs to turn another 180 degrees to face the right way. I haven't taken a wrench to it yet, because in reading online, some people are saying that once it is finger tight, it should go another 2 rotations with a wrench. This seems like an awful lot to me. Initially I thought that turning it the 180 degrees with a wrench seemed like it might be too much, but now I'm not so sure. My main concern is that I don't want it to leak, since that was the problem before which caused me a lot of time and money to fix.
The part says it is an NPT fitting, and I believe they are brass.
So, am I OK to turn it the 180 degrees with a wrench? Should I be giving it an additional rotation? I don't want to break the dishwasher, but I also don't want any leaks. I will be using several rotations of teflon tape.
