What You Need to Know About Oxygen

Oxygen fuels your fire. More oxygen helps charcoal burn hotter and faster. Less oxygen slows the burn and lowers cooking temperatures.
Open vents to increase heat. More airflow means hotter coals.
Close vents to reduce heat. Limit oxygen to cool things down.
Pro Tip: Always leave vents partially open so the fire doesn’t suffocate completely.

How to Keep Your Charcoal Grill Hot

For high-heat grilling, open the vents wide to allow maximum airflow. This keeps your coals burning hotter and is ideal for searing meats or quick cooks.

How to Cool a Charcoal Grill Down

To slow cooking or lower the temperature:

Partially close the vents to restrict airflow.
Don't close vents completely — this can extinguish the fire.

How to Manage Flare-Ups

Flare-ups happen when fat drips onto hot coals. Avoid using water, as it creates ash and can cause a fire hazard. Instead:
Create a two-zone fire: one side with coals, the other empty.
Move food to the cooler side when flare ups occur until the flames subside.
Use long-handled tongs or a spatula for safe handling.

How to Increase Heat on a Grill

Need more heat mid-cook?

Add unlit Kingsford™ Original Charcoal Briquets on top of lit coals. In about 15 minutes, these coals will be ready, providing that extra heat.
Or light a chimney with fresh coals and add them when ready.
Important: Never add Match Light™ Charcoal to already lit coals, instead use Kingsford™ Original Charcoal. Match Light™ Charcoal should never be used in a chimney.

Frequently Asked Questions

To maintain high heat, keep the vents fully open and add fresh briquets as needed. This ensures a steady oxygen flow and a high temperature. If you’re planning a long cook, start with a full bed of Kingsford™ Original charcoal and have extra briquets ready to add during grilling.

Flare-ups are common when fat drips onto hot coals, but don’t panic. Move food to a coal-free zone and wait for flames to die down naturally. Avoid using water, as it can create ash and cause uneven cooking. A two-zone fire setup is the best way to manage flare-ups safely.

Yes. Your grill’s vents are the easiest way to control temperature without adding fuel. Opening vents increases airflow and heat, while closing them partially reduces oxygen and cools the coals. This method is perfect for fine-tuning temperature during longer cooks.
