Introduction
The Kamado Joe Classic Joe I is an 18-inch ceramic charcoal grill and smoker designed for versatile outdoor cooking. Its thick-walled, heat-resistant shell efficiently locks in smoke and moisture, allowing for precise temperature control across a wide range, from low-and-slow smoking at 225°F to high-heat searing at 750°F. This manual provides essential information for setting up, operating, maintaining, and troubleshooting your grill to ensure optimal performance and longevity.

Unpacking and Assembly

- Assemble the cart and attach the side shelves according to the included assembly instructions. Ensure all bolts are securely tightened.
- With assistance, lift the ceramic grill body and place it securely into the assembled cart.

Operating Instructions
The Kamado Joe Classic Joe I offers exceptional control over cooking temperatures, making it suitable for various culinary techniques.
Lighting the Charcoal
- Load the firebox with lump charcoal. Avoid using briquettes as they can impart undesirable flavors.
- Use a natural fire starter (e.g., fire starter cubes or electric starter) to ignite the charcoal. Allow it to burn for 10-15 minutes with the lid open until a small bed of embers is established.
Temperature Control
- Control Tower Top Vent: Adjust the top vent to control the airflow out of the grill. A wider opening increases temperature, while a smaller opening reduces it.
- Bottom Vent: The bottom vent controls the airflow into the firebox. Adjust this in conjunction with the top vent for precise temperature management.
- Built-in Thermometer: Monitor the internal temperature of the grill using the thermometer located on the lid.

Cooking System
The 2-Tier Divide & Conquer Flexible Cooking System allows you to cook different foods at various temperatures simultaneously. This system includes:
- Multi-level Rack: Position cooking grates at different heights for varied heat exposure.
- Half-Moon Heat Deflectors: Use these ceramic plates to create indirect cooking zones, ideal for smoking or roasting.
- Half-Moon Cooking Grates: Cook directly over the charcoal or over the heat deflectors.

Maintenance
Regular maintenance ensures your Kamado Joe Classic Joe I remains in excellent condition and performs optimally for years.
Ash Removal
The patented Slide-Out Ash Drawer makes cleanup simple. After the grill has completely cooled:
- Open the bottom vent.
- Slide out the ash drawer.
- Empty the ashes into a non-combustible container.
- Replace the ash drawer and close the bottom vent.

Cleaning and Care
- Cooking Grates: After each use, burn off any food residue by closing the lid and opening the vents to high heat for 10-15 minutes. Once cooled, brush the grates clean with a stiff wire brush.
- Ceramic Interior: The ceramic interior is self-cleaning at high temperatures. Do not use water or chemical cleaners inside the grill.
- Felt Gasket: Regularly inspect the felt gasket around the lid for wear and tear. A well-maintained gasket ensures an airtight seal for optimal heat and smoke retention. Replace if necessary.

Troubleshooting
Here are some common issues and their solutions:
- Difficulty Reaching High Temperatures: Ensure both top and bottom vents are fully open. Check for sufficient charcoal and that the ash drawer is not clogged.
- Difficulty Maintaining Low Temperatures: Ensure both top and bottom vents are adjusted to minimal openings. Check that the lid gasket is sealing properly. Too much charcoal can also make it difficult to maintain very low temperatures.
- Excessive Smoke: This is normal during the initial lighting phase. If excessive white smoke persists, ensure proper airflow and that only lump charcoal is being used.
