Replace text menu items with custom icons

Hello

I’ve added a secondary menu to the top bar and created custom icons through Fontello, which I’ve imported via the import/export area of the site. The icons are available in the icon area of the advanced editor. All I’d like to do is replace certain navigation titles with the custom icons I’ve uploaded, but it doesn’t seem to work. In the navigation area of the menu item I’ve added

<i class=”xandari avia-font-entypo-fontello”></i> (I found from another tutorial)

in css I’ve added:

.xandari {
content:’\ue802′;
font-family: “fontello”;
}

I don’t want any text, just the icon. But it doesn’t seem to recognize the icon code I’ve used. I obtained the code from the advanced editor, inserting an icon and hovering over the custom icon I uploaded. I’m thinking I’m not calling the right font-family..what is the font family for custom icons?
