Janet,

Simple procedure. Remove the black plastic retainers at the top by pushing down turning to unlock. Tilt the top of the old grill out and pull it up and away from it's lower mountings. Place the foot tabs of the new grill in the slots in the lower sheet metal support with the top of the grill tilted out slightly ... once the tabs are seated tilt the top up into place and reinstall the plastic retainers by pushing them down and turning 45 degrees to lock. Just be careful. make sure everything's seated and lined up and don't force anything. A piece of cake. Hope this helps and your new grill makes your Brick look great.
