Don't want "Home" to Display on Static site

We're using the Catch Box theme as a "landing page" of sorts. It will be a one page, static site. So we want to remove the word "Home" that appears in the header. I don't have a Primary menu (or any menu) enabled. I've tried a million things --css, functions.php edits, but cannot get rid of it! The fixes said to work in the WP forum don't seem to work for this theme. I only want to get rid of the word Home, and keep the wide "nav" bar that separates the header from the content. Please help!
