remove leave a reply form from template

I am using business portfolio theme on and a few other sites. I do not want the leave a reply form to be on pages and posts that are made. I have been going through the code and am having a real problem finding what I need to change. Any help would be appreciated. I will not be allowing any comments on these sites at all so the code can be deleted completely. However, I may want to just remove it from certain templates on other sites.
