If your puppy starts ringing the bell just to go out and play, you need to teach him that ringing the bell is only about potty training. When he rings the bell, put on his leash and take him to the place where you want him to relieve himself. Give him a few minutes, and if he relieves himself, praise and give him a treat. If he doesn't, take him straight back in. Over time, your dog will learn that ringing the bells means the door opens and they can go out to relieve themselves.
