Genuine Weber 70397 burner assembly for Summit gas

Verify your grill model

The assembly fits 59 specific Summit model numbers produced between 2007 and 2009, including E-450, E-620, E-650, S-420, S-450, S-470, S-650 and S-670 variants. Confirm that your unit is a natural-gas version; this part is not suitable for propane-fuelled grills.
