A frequently asked question from our Facebook and Twitter fans is which side of the cast iron grates should be facing up when grilling? This question would apply to fans that have a Genesis or Spirit series gas grill.
The wider, flat side of the cooking grates should be facing upwards for cast iron grates. The underside is more pointed like the top of a triangle. There are four small legs in each corner on the underside of the grate to ensure a level cooking surface. This will help stabilize the food. Additionally, the wider, flat side of the grates will be easier to clean after grilling.
