Cross Over Burners Allow Flames To Ignite Other Burners.

Cross over burners install perpendicular to the main barbecue grill burners because cross-over burners are not designed to augment heat while grilling or barbecuing. Crossover burners are part of the gas BBQ ignitor. As the ignition lights the fuel in one burner the flames are able to use the cross-over burner to jump to the next burner because of the fuel emitted from the ports of the next burner. As long as naked ports are leaking fuel without flame, the fire will crossover to the fuel and use the ross-over burner between each main grilling burner to ensiure full ignition.
