Make sure you are installing your Flat Top on the right-hand side of your grill. With the burners off and the grill cool to the touch, remove the grate on the right.
Place your WEBER CRAFTED frame in the right-hand side of the grill. It should be positioned with the curved portions of the wire facing down. The WEBER logo should be toward the front of the grill and facing up.
Place your Flat Top over the frame.
Place the spacer between the Flat Top and the front of the grill. Make sure that the spacer’s two large tabs are positioned toward the inside of the grill, closest to the grillware.
If you are still experiencing issues with the fit of your Flat Top, please contact customer support.
