Operating Instructions
The Primo Oval XL 400 is a versatile ceramic grill capable of grilling, baking, roasting, and smoking. Its superior heat retention allows for precise temperature control.
1. Adding Charcoal
Open the lid and the stainless steel draft door. Add a sufficient amount of lump charcoal to the firebox. Avoid using briquettes as they can produce more ash and chemicals.

2. Lighting the Charcoal
Use a natural charcoal starter or an electric starter to ignite the lump charcoal. Allow the charcoal to ignite fully and develop a small bed of embers before closing the lid.
3. Temperature Control
Adjust the temperature by controlling the airflow through the cast iron top vent and the stainless steel draft door. Opening both vents increases airflow and temperature, while closing them reduces airflow and temperature. Make small adjustments and allow time for the temperature to stabilize.
4. Cooking
Once the desired temperature is reached, place your food on the cooking grates. The oval shape allows for direct and indirect cooking simultaneously. Monitor the internal temperature using the lid thermometer.
Care and Maintenance
Proper care ensures the longevity and optimal performance of your Primo grill.
1. Ash Removal
After each use and once the grill has completely cooled, use the provided ash tool to remove excess ash from the firebox. Regular ash removal prevents airflow restriction and maintains cooking efficiency.

2. Cleaning Cooking Grates
The porcelain-coated cooking grates can be cleaned with a grill brush after each use while still warm. For deeper cleaning, remove the grates and wash with warm soapy water.
3. Exterior Cleaning
Wipe down the exterior ceramic surface with a damp cloth. Avoid abrasive cleaners that could damage the finish. For the metal components, use a mild detergent and water.
4. Gasket Inspection
Periodically inspect the high-temperature gasket around the lid for wear and tear. A damaged gasket can lead to heat loss and inefficient cooking. Replace if necessary.
Troubleshooting
This section addresses common issues you might encounter with your Primo Oval XL 400 grill.
Issue: Grill not reaching desired temperature.
- Solution: Ensure both the top vent and bottom draft door are sufficiently open to allow maximum airflow. Check for excessive ash buildup in the firebox, which can restrict airflow. Use dry lump charcoal.
Issue: Temperature is too high or difficult to control.
- Solution: Gradually close the top vent and bottom draft door to reduce airflow. Make small adjustments and wait a few minutes for the temperature to stabilize. Avoid opening the lid frequently, as this introduces oxygen and can cause temperature spikes.
Issue: Smoke leaking from the lid.
- Solution: Inspect the high-temperature gasket around the lid. If it appears worn, cracked, or compressed, it may need replacement to ensure a proper seal.
