Questions about this item

How do I install the Weber 67728 cookbox on my Genesis 300 series grill from 2007?

Remove the old cookbox by detaching the burner tubes, heat deflectors and cooking grates; then lower the new WEB67728 cookbox into the cart frame, re-attach the burner tubes to the manifold, reposition the heat deflectors and grates, and verify all fasteners are secure before first use.

What maintenance will the Weber 67728 cookbox need over time?

Brush the porcelain-enamelled interior after each cook while it is still warm, empty the grease tray regularly, and inspect the burner ports annually for blockages that could affect flame pattern.

What is the first limit I will hit when running the Genesis 300 at high heat for long periods?

The porcelain enamel finish can discolour or craze if temperatures exceed the grill's design range for extended sessions, so avoid sustained maximum output beyond normal pre-heat and searing cycles.
