Setup and Initial Seasoning
Before the first cook, remove all packing material and inspect grates, burners, and grease management for debris. A proper initial clean prevents off-flavors and helps the finish cure evenly.
Apply a light coat of high smoke point oil to grates and parts, then heat the unit to 350°F for an hour to set the seasoning and protect the surfaces from rust.
Temperature Control and Heat Zones
Creating Direct and Indirect Areas
On Q BBQ units with multiple burners allow one or two burners on high for direct sear and leave the others off for gentle indirect cooking. This setup gives you control over flare ups and steady low-and-slow temperature.
Using the Smoke Stack and Air Dampers
Open the smoke stack and bottom dampers fully when starting a cook to establish strong airflow. Adjust in small increments to hold consistent temps, especially in windy or cold conditions.
Fuel, Burners, and Safety
Propane Hookup and Pressure Settings
Use a certified propane regulator and check hose connections with soapy water for bubbles before igniting. On Q BBQ burners are designed for clean blue flames, so yellow tips signal improper pressure or blockage.
Leak Checks and Wind Management
Perform a leak test every few weeks by brushing a baking soda solution on valves and lines; fizzing indicates a leak. Shield the grill from heavy crosswinds with a cover or placement to maintain stable combustion.
Maintenance and Long-Term Performance
After each cook, brush grates while warm, empty the grease catch pan, and inspect heat shields for buildup. Regular cleaning keeps smoke production clean and prevents bitter tastes on future food.
Cover the unit when not in use and store regulators indoors to extend life. Periodic checks on burner ports and valve screens prevent clogs that can cause uneven heating or hard starts.
Best Practices for Consistent On Q BBQ Results
- Preheat the grill with all burners on high for 10 to 15 minutes before cooking
- Use a two-zone setup with one or two burners high for sear and the rest off for indirect cooking
- Keep a spray bottle and heat resistant gloves within reach for flare up control
- Monitor temperatures with a grill thermometer and adjust dampers in small steps
- Clean grates and grease traps after every use to preserve seasoning and flavor
- Store the grill covered and check valve connections seasonally for safety
FAQ
Reader questions
How do I know when my On Q BBQ is fully preheated?
Wait until all burner flames are steady and the grill grates reach around 400°F measured with an infrared thermometer or an oven thermometer placed near the cooking surface.
Can I sear with all burners on high and still control temperature?
Yes, but plan for a temporary spike in heat. After searing, move food to an unlit zone or reduce burners one at a time to stabilize temperature for finishing.
What is the best way to manage flare ups on an On Q BBQ?
Keep a spray bottle of water nearby, move food to a cooler part of the grill, and close the lid to temporarily snuff flames without starving the fire of oxygen.
How often should I replace the propane regulator and check connections?
Inspect the regulator and hoses at least once per grilling season and replace the regulator every few years or if you notice inconsistent flame patterns or pressure loss.
