2.3 Propane Tank Connection
Connect a standard 20 lb propane tank (not included) to the griddle's regulator. Ensure all connections are tight and check for leaks using a soapy water solution before first use. Refer to the propane tank manufacturer's instructions for safe handling.
2.4 Initial Seasoning
Before first use, the griddle surface must be seasoned. This process creates a non-stick surface and protects against rust. Apply a thin layer of cooking oil (e.g., flaxseed, vegetable, or Blackstone seasoning blend) to the entire griddle surface. Heat the griddle on medium-high until the oil smokes and turns dark. Repeat this process 3-4 times, allowing the griddle to cool slightly between layers.
3. Operating Instructions
3.1 Ignition
- Ensure the propane tank valve is fully open.
- Turn all burner control knobs to the 'OFF' position.
- Push and turn one burner control knob to the 'LOW' position.
- Press the igniter button repeatedly until the burner lights.
- Once lit, adjust the flame to the desired cooking temperature.
- Repeat for additional burners as needed.
3.2 Temperature Control
The griddle features two independently controlled burners, allowing for dual cooking zones. Each burner has multiple power levels, providing precise temperature management across the 527 square inches of cooking surface. Adjust the control knobs to achieve different heat zones for various foods.

3.4 Grease Management System
The griddle is equipped with a rear grease management system. Excess grease is channeled through an opening at the back of the griddle surface into a removable grease cup. This design helps keep the cooking area clean and simplifies cleanup.
3.5 Side Shelf and Tool Hooks
A convenient side shelf provides ample space for food preparation and serving. Integrated hooks are included for hanging cooking tools, keeping them accessible while cooking.
4. Maintenance
4.1 Cleaning the Griddle Surface
- After each use, while the griddle is still warm, scrape off food debris with a griddle scraper.
- Wipe the surface clean with paper towels.
- Apply a thin layer of cooking oil to re-season and protect the surface.
- Do not use soap or harsh chemicals on the griddle surface, as this can remove the seasoning.
4.2 Cleaning the Grease Management System
Regularly empty and clean the grease cup located at the rear of the griddle. Wash the grease cup with warm, soapy water and rinse thoroughly.
4.3 Griddle Cover
The included Blackstone Patio Series 28” Griddle Cover is made from robust 600D polyester fabric, offering weather resistance and UV protection. Use the cover to protect your griddle from the elements when not in use. Secure the cover with the side buckles for a snug fit. The front zipper allows for easy access without full removal.
4.4 General Care and Storage
Store the griddle in a dry, protected area when not in use for extended periods. Periodically check all connections and components for wear or damage. Keep the griddle clean to ensure longevity and optimal performance.
5. Troubleshooting
5.1 Common Issues
- Burner Not Lighting: Check propane tank level, ensure gas flow, verify igniter spark. Clean burner ports if clogged.
- Uneven Heating: Ensure griddle is level. Allow sufficient preheating time. Clean burner tubes if partially blocked.
- Low Flame: Check propane tank for low fuel. Ensure regulator is properly connected and not in bypass mode.
- Excessive Smoke: This may occur during initial seasoning or if too much oil is used. Ensure proper ventilation.
