Setup
Assembly
Assembly of the Blackstone griddle is required. Follow the detailed instructions provided in the separate assembly guide that came with your product. Ensure all parts are present and securely fastened before proceeding to the next steps.
Propane Tank Connection
- Ensure the griddle control knobs are in the "OFF" position.
- Connect the regulator hose from the griddle to the propane tank valve. Hand-tighten securely.
- Open the propane tank valve slowly to allow gas flow.
- Perform a leak test: Apply a soapy water solution to all connections. Bubbles indicate a leak. If a leak is detected, close the tank valve, tighten connections, and retest. Do not operate if leaks persist.
Initial Seasoning of the Griddle Top
Before first use, the griddle top must be seasoned to create a non-stick surface and protect against rust. This process involves applying a thin layer of cooking oil and heating the griddle until the oil smokes and darkens. Repeat this process several times.
- Clean the griddle surface thoroughly with hot, soapy water to remove any manufacturing residues. Rinse and dry completely.
- Apply a thin, even layer of high smoke point cooking oil (e.g., flaxseed, avocado, or Blackstone Griddle Seasoning) to the entire cooking surface.
- Turn the griddle burners to medium-high heat. The oil will begin to smoke.
- Continue heating until the griddle stops smoking and the surface turns dark brown or black.
- Turn off the burners and allow the griddle to cool.
- Repeat steps 2-5 at least 3-4 times, or until a dark, even seasoning layer is achieved.

Operating Instructions
Ignition

- Push and turn a control knob to the "HIGH" position.
- Press the electronic igniter button repeatedly until the burner ignites. You should hear a clicking sound and see a flame.

Maintenance
Cleaning the Griddle Top
Proper cleaning and re-seasoning after each use are crucial for maintaining your griddle's performance and preventing rust.
- While the griddle is still warm (but not hot), scrape off any food debris using a griddle scraper.
- Push excess grease and food particles into the rear grease management system.
- For stubborn residue, pour a small amount of water onto the griddle surface while it's still warm to deglaze, then scrape clean.
- Wipe the surface clean with paper towels.
- Apply a very thin layer of cooking oil to the entire griddle surface to maintain the seasoning and prevent rust.
