You can embed the feed directly into a template file by using the WordPress do_shortcode function:
<?php echo do_shortcode('[custom-facebook-feed feed=1]'); ?>
Note: The feed number for your feed may be different than in this example. You can get the correct shortcode by navigating to WordPress Dashboard > Facebook Feed > All Feeds and checking the Shortcode column. The button to the right of the shortcode will copy it to your clipboard.
