Ensure all parts are accounted for before beginning assembly. It is recommended to have a second person assist with assembly due to the size and weight of some components.
4.2 Connecting the Liquid Propane Tank
- Ensure all burner control knobs are in the OFF position.
- Open the cabinet doors located beneath the grill.
- Place the liquid propane tank securely in the designated tank holder.
- Connect the regulator hose from the grill to the propane tank valve. Hand-tighten the connection firmly.
- Slowly open the propane tank valve fully.
- Check for any gas leaks using a soapy water solution on all connections. Bubbles indicate a leak. If a leak is detected, close the tank valve, tighten connections, and re-test. If the leak persists, do not use the grill and contact customer service.

5.3 Using the Sear Zone
The extra-large sear zone is designed for high-heat searing to achieve perfect grill marks and lock in juices. To activate the sear zone, turn the dedicated sear zone burner knob to the HIGH position. Allow it to preheat for 5-10 minutes before placing food directly over it.
5.4 Using the Side Burner
The integrated side burner allows you to sauté vegetables, boil corn, or heat up sauces while grilling. To light the side burner, open its cover, turn the control knob to the START/HIGH position, and press the electronic ignition button until it ignites.

5.6 Cooking Techniques
- Direct Heat: Use direct heat for searing, grilling smaller items, or cooking foods that require quick cooking.
- Indirect Heat: For larger cuts of meat, poultry, or delicate items, use indirect heat. Turn off the burners directly beneath the food and use adjacent burners to maintain the desired temperature. The expandable top cooking grate provides additional space for indirect cooking.

6. Maintenance
6.1 Cleaning the Cooking Grates
After each use, while the grates are still warm, use a grill brush to scrape off any food residue. For a deeper clean, remove the grates and wash them with warm, soapy water.
6.2 Grease Management System
The improved grease management system simplifies cleaning. Simply pull the grease tray out from the front of the grill and scrape away accumulated grease and debris. Replace the disposable catch pan as needed.
