4. Gas Connection (Natural Gas)
This grill requires a permanent natural gas supply line. Connection must be performed by a qualified gas technician in accordance with local codes and ordinances. Ensure the gas supply is turned off before making any connections. Use only approved gas supply hoses and fittings.
5. Leak Test
After connecting the gas supply, perform a leak test. Mix a solution of equal parts liquid dish soap and water. With the gas supply turned on, apply the solution to all gas connections. Bubbles indicate a leak. If a leak is detected, turn off the gas supply immediately, tighten the connection, and retest. Do not operate the grill if a leak persists.
Operating Instructions
1. Before Each Use
- Ensure the grill area is clear of flammable materials.
- Check all gas connections for leaks (refer to Leak Test in Setup section).

2. Lighting the Main Burners

Care and Maintenance
Regular cleaning and maintenance will extend the life of your grill and ensure optimal performance.
1. Cleaning the Cooking Grates
After each use, while the grates are still warm, brush off any food residue with a stiff wire brush. For deeper cleaning, remove the grates and wash with warm soapy water, then rinse and dry thoroughly.
2. Cleaning the Burners
Periodically inspect burner ports for blockages (e.g., from food debris or insects). Use a wire brush or a small wire to clear any obstructions. Ensure burner tubes are free of spider webs or insect nests, which can cause flashback fires.
3. Cleaning the Drip Tray
Empty and clean the drip tray regularly to prevent grease fires. Wash with warm soapy water and rinse thoroughly.
4. Exterior Cleaning
Wipe down stainless steel surfaces with a soft cloth and a stainless steel cleaner or mild soapy water. Always wipe in the direction of the grain to prevent scratching. Avoid abrasive cleaners or pads.
5. Storage
When not in use, cover the grill with a weather-resistant grill cover to protect it from the elements. If storing for an extended period, disconnect the natural gas supply and ensure the grill is clean and dry.
