This is the code for the comments area of the template
<?php comments_template(); ?>
<div class="hidden"><?php wp_list_comments(); ?></div>
<?php next_comments_link(); previous_comments_link(); ?>
<div class="hidden"><?php comment_form(); ?></div>
<?php do_action('comment_form_before'); ?>
<?php do_action('comment_form_after'); ?>
I also checked these
-- If checked, Facebook comments will be used instead of, or in addition to, regular WordPress comments.
-- By default, Facebook comments will appear in addition to WordPress comments.
Check this box if you wish to disable WordPress comments, but still allow Facebook Comments.
Note: if you enable this option, Facebook Comments will always appear, disregarding any WordPress settings.

Thanks
