Usage Features:

Getting Started:

LP Tank Installation: The manual provides detailed steps for safely installing the LP tank onto the tank scale inside the grill cabinet. It emphasizes checking the tank valve for proper mating with the regulator and inspecting for damage or debris. The hose retention clip must be secured to the tank scale to prevent damage.
Leak Checking: A crucial safety step, the manual outlines how to perform a leak check using a soap and water solution on all fittings (regulator to tank, gas hose to bulkhead, bulkhead to corrugated gas line). It describes how to identify a leak by observing bubbles and provides instructions on what to do if a leak is found, stressing that the grill should not be operated with a gas leak.
Refilling or Replacing an LP Tank: The grill features an easy-to-read fuel gauge to indicate the amount of fuel remaining. Instructions are provided for safely removing an empty tank and installing a refilled or new one, with additional leak check precautions for reinstalled tanks.

Operation:

Initial Burn-Off: Before first use, the grill should be preheated on the highest setting with the lid closed for at least 20 minutes to burn off any manufacturing residues.
Every Time You Grill (Meal-to-Meal Maintenance):
- Check for Grease: Before each use, the slide-out grease tray and catch pan must be checked for grease build-up and cleaned to prevent fires.
- Inspect the Hose: The fuel hose should be routinely inspected for cracks, abrasions, or cuts. A damaged hose must be replaced with a Weber-authorized part.
- Preheat the Grill: Preheating is essential for preventing food from sticking and achieving proper searing. The grill should be preheated with all burners on the start/high position for 15 minutes with the lid closed.
- Clean the Cooking Grate: After preheating, the cooking grates should be brushed with a stainless steel bristle grill brush to remove any food debris.
Igniting the Grill (Electronic Ignition System): Step-by-step instructions are provided for igniting the main burners, starting from the leftmost burner. The lid must be open during ignition, and the electronic ignition button should be pushed and held until the burner ignites. If a burner fails to ignite, the control knob should be turned off, and a five-minute wait period is required before reattempting.
Using the Sear Zone: The sear zone is designed for intense, direct heat to create sear marks. Instructions detail how to ignite the sear burner, preheat the grill, and use the sear zone in tandem with adjacent burners for optimal searing, followed by indirect cooking to finish the meal.
Igniting the Side Burner: Similar to the main burners, the side burner can be ignited using the electronic ignition system. The side burner lid must be open during ignition.
Extinguishing Burners: All burner control knobs should be turned to the off position, and the gas supply at the LP tank should be turned off.
