5. Operating Instructions
5.1. Preparing the Grill
- Ensure the grill is clean and free of debris.
- Place the grill on a stable, non-combustible surface outdoors, away from any flammable materials.
- Open the lid and remove the cooking grids.
5.2. Lighting Charcoal
- Place charcoal briquettes or lump charcoal on the charcoal grate at the bottom of the grill. Do not overfill.
- Arrange charcoal in a pyramid shape for easier lighting.
- Apply a small amount of charcoal starter fluid (if using) evenly over the charcoal. Wait 30 seconds for the fluid to soak in.
- Carefully light the charcoal using a long-stemmed match or lighter.
- Allow charcoal to burn until covered with a light gray ash (approximately 15-20 minutes). Spread the coals evenly.
- Carefully place the cooking grids back into position using heat-resistant gloves.
5.3. Temperature Control
The adjustable chimney vent allows for precise control over airflow, which directly impacts the grill's temperature and smoke production.

- To Increase Temperature: Open the chimney vent further to allow more oxygen to reach the coals, increasing the burn rate and heat.
- To Decrease Temperature: Close the chimney vent partially to restrict oxygen flow, reducing the burn rate and heat.
- Adjust gradually and monitor the internal temperature if your grill has a thermometer.

6. Maintenance and Cleaning
Regular cleaning and maintenance will extend the life of your grill and ensure optimal performance.
- After Each Use: Allow the grill to cool completely.
- Cleaning Cooking Grids: Use a grill brush to scrape off food residue from the cast iron cooking grids. For stubborn residue, wash with warm soapy water, rinse thoroughly, and dry immediately to prevent rust. Lightly oil cast iron grates after cleaning to maintain seasoning.
- Ash Removal: Once cooled, remove the ash catcher and dispose of ash safely. Ensure no hot embers remain.
- Exterior Cleaning: Wipe down the exterior surfaces with a damp cloth and mild detergent. Dry thoroughly.
- Storage: Store the grill in a dry, protected area when not in use. Consider using a grill cover to protect it from the elements.
