houzz icon on social profiles

Hello,
I can’t get the houzz icon to work with social profiles, I downloaded and installed the zip file from fontello. I can use the houzz icon in an icon box.
I added the following with functionality plugin:

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘houzz’] = array( ‘font’ =>’fontello’, ‘icon’ => ‘ue801’);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘Houzz’] = ‘houzz’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);

I tried it with ‘font’=>’houzz’ instead fontello, but that didn’t work either. The link to my houzz page works, it’s at the bottom right end of the socket, but the icon is invisible.
