Module Positions
There are 40 module positions with this template that are collapsible (if no modules are published to the position, it will not appear).
Logo & Toolbar are conditional positions. There are other elements which occupy these areas, such as the logo image for Logo and the fusion menu for Toolbar. When you publish a module to these positions, it will collapse the theme element and replace with your module. If you wish to disable everything, hide the various elements in Extensions → Template Manager → rt_iridium_j15. Such an example would be setting Show Logo to No.
View all module positions live by appending ?tp=1 or &tp=1 to the end of your URL such as http://yoursite.com/index.php?tp=1.
The below diagram is of the Module Variations page.
