Summarize the following:
Turn the burners on a gas grill to medium. If you're using a charcoal grill, fill a chimney with briquettes and light them. Dump the hot briquettes on one half of the grill. Dumping the briquettes on one half of the grill will make a two-zone fire. This will give you an indirect source of heat when you grill the sausages.

Summary:
Heat a gas or charcoal grill to medium heat.
