Exclude Page Code Fix

I don’t know PHP, and I want to exclude pages from the page list in my header. How do I do that? I read https://codex.www.ads-software.com/wp_list_pages#Exclude_Pages_from_List

but my title code is a bit different. And when I try to use this it gives me errors. Please some one make me the code to exclude pages (page ID 228) so that I can put it in my site.

The page list code is something like this in my theme:

<?php wp_list_pages ('sort_column=menu_order&depth=1&title_li='); ?>

Thanks,
