Just like WP-PageNavi, the WP-CommentNavi plugin adds advanced pagination for paginated comments.
The Graphene theme natively supports WP-CommentNavi, so all you have to do is install the plugin and activate it. The plugin will then work right away using its default configurations, but you can configure the settings yourself.
