Mounting 5Y3GT tubes

anonymousMounting 5Y3GT tubes
I have read that the 5Y3GT tube should be mounted  
vertically, or upright, as opposed to being mounted horizontally. And if it is mounted in a horizontal position, it says that pins 2 and 7 must be in a horizontal plane. Can someone explain to me why this tube , as well as others,  
have this limitation?  
 
Thanks for any help!
