I layed all the pipes out when I got them and I only have one pipe with the two 45 degree bends. I thought it was odd but figured maybe there was something I didnt know. I have not seen the install doc you posted, so ill go back and look at it and try to straighten it out. Ill double check to make sure I have the correct pipes. If not Ill just call the vendor back, and Im sure he will be more than willing to correct the problem.
