repair 2 layer drywall

[flatlander]

Hi,
I've been looking all over the net for the proper method to repair a 8 inch square hole in a 2 layer fire rated wall.
I know there must separation of seams but how much?

I thank you for any help.

This link will open a PDF or place it in your "download" files, you may have to look there after opening the link. It is showing fire rated drywall repair. Don't know if it will help or not.
