[Amps] Question on installing new Amp tube

[w4foa at comcast.net]

Please forgive my ignorance. 
I am going to install a new (old stock) 3-500Z in my amp. Are there procedures that I must follow. I've read and heard about "getting" but I don't have a clue what that means. I think it means "burning in" but not clear what the procedure should be. 
Anyone help? 
Thanks in advance!
