First use and burn-off

20 minutes on high, lid closed

The manual: heat the grill on its highest setting, lid closed, for at least 20 minutes before you grill for the first time. Weber gives no other seasoning step.

1. Peel the protective film off the stainless parts (the assembly guide).
2. Check every part is fitted and all hardware is tight (the assembly guide).
3. Do the leak test first.
4. Light all the burners, the Sear Zone too.
5. Close the lid and leave every knob on high for at least 20 minutes.
6. Turn it off: knobs, then the cylinder.
