To start using the grill, pour wood pellets into a hopper (pellets are usually are made from compressed sawdust). Press the start button to ignite the pellets, which are fed into the fire box with an auger, where a controlled number of pellets are lit and burned (depending on the temperature setting selected). The auger adjusts the number of pellets entering the fire box to maintain the desired temperature.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
