Pellet grills work off of electricity, so they need an outlet to supply their power. That electricity allows the grill to move pellets into the hopper and funnel them down to a firepot using a rotating auger and motor. Once the pellets hit the firepot an igniter rod sparks a flame and smoke is produced. The electricity powers a fan that blows that smoke and heat upwards which then provides smoky, convection cooking throughout the grill. All of this is taken care of by your Alpha Connect controller, so you don’t have to worry about anything but eating!
