Stenner rookie. Injection point vertical vs horizontal?

I have Stenner coming and I have a question regarding the injection point. I had intended to remove an inline puck feeder and utilize it's tee as the injection point. Removing the feeder (Pentair 320) seemed simple enough but I had a hard time unscrewing it. It finally came off. However, I then found out why I had a hard time. There was a ridiculous set screw that was well hidden and it chewed up the threads on the tee. I was able to get the new reducer screwed on but it leaks. I gather the chewed up threads are to blame. At any rate, since I'm going to have to re-plumb now, is there a preference/requirement as to whether the injection point is vertical or horizontal?
