Setup and Installation
Before beginning installation, ensure your grill is completely cool and disconnected from its fuel source. It is recommended to wear protective gloves.
- Remove Old Components: Open the grill lid and carefully remove the cooking grates and any existing heat plates. Then, detach the old burners and crossover tubes. Note their orientation for easier reassembly.
- Clean Grill Interior: While the grill is disassembled, take the opportunity to clean out any grease, debris, or rust from the firebox. This will improve performance and safety.
- Install New Burners: Carefully place the new stainless steel burners into their designated positions. Ensure the gas inlet end of each burner properly aligns with the gas valve orifices.
- Connect Crossover Tubes: Attach the adjustable crossover tubes between the burners. These tubes help distribute flame evenly. Adjust their length as needed to fit securely and use the provided pins to fasten them.
- Place Heat Plates: Position the new porcelain steel heat plates over the burners. Ensure they sit securely and cover the burners adequately to distribute heat and protect them from drippings.

Operating Your Grill with New Parts
After installation, perform a leak test on all gas connections before lighting the grill. Refer to your grill's original instruction manual for specific lighting procedures.
- Initial Burn-Off: Before cooking, preheat the grill on high for 10-15 minutes to burn off any manufacturing residues.
- Even Heat Distribution: The new heat plates and burners are designed to provide consistent heat across the cooking surface. Monitor your food closely during initial uses to familiarize yourself with the grill's renewed performance.
- Flame Appearance: Observe the flames. They should be primarily blue with yellow tips. Irregular or excessively yellow flames may indicate an issue with gas flow or burner alignment.
Maintenance
Regular maintenance will prolong the life of your replacement parts and ensure safe grilling.
- Cleaning Heat Plates: After each use, once the grill has cooled, scrape off any food debris or grease from the heat plates. Periodically, remove them and wash with warm, soapy water. Ensure they are completely dry before reinstalling.
- Cleaning Burners: Use a soft brush (not wire) to gently clean the burner ports to prevent clogging. Ensure all ports are clear for even flame distribution. Do not use abrasive cleaners on stainless steel.
- Inspect Crossover Tubes: Check crossover tubes for any blockages or corrosion during cleaning.
- Storage: If storing the grill for an extended period, ensure all components are clean and dry. Consider covering the grill to protect it from elements.
