You first need to make it a fun place to be which after awhile he will know it is their safe haven and a great place to be. With mine I keep them in a crate when I can't keep my eye on them for the first year. During the day give him toys and things which he simply adores in the crate. I fed my guys in their crates each meal with the door closed and let them out to go to the bathroom and play for awhile afterwards. Then put him back in with a fun toy maybe a kong stuffed with chicken pieces and treats. Some people and I have also stuffed the Kong toy with his first meal and let him get it out if that works do it with the second meal also. Do this till he gets used to the crate. At night leave a radio and night light on....Good luck and hope it doesn't take too long. Takes time but well worth it. Take his bed away if he is peeing on it till he is trained. For some reason they pee on blankets and beds. LOL Just my opinions and what has worked for me.
