You can do the following guide.

1. Go to cPanel -> File Manager -> public_html -> {publish_folder}/

        Sample::

domainname.com, should be in public_html

        domainname.com/myname, should be public_html/myname (if your public_html doesn’t have this folder, just feel free to create it)

2. Create a new file under the folder in number 1. with the name such as; feed.html

and insert your RSS FEED code to the file.

3. Back to RVsitebuilder -> Pages, on Page Editor of the page you want, place mouse on the block you want to insert Feed, and click on “html mode” icon on TEXT Properties toolbar. Then insert the following code:

 <object type="text/html" data="feed.html" width="100%"></object>

*feed.html is the file you created in number 2.

4. Republish again.
