Changing a burner on your Char-Broil gas grill is not a difficult project. Before purchasing a replacement, remove the old burner and take it to the store. Char-Broil grills have different size burners depending on which model you own. The burner secures to the grill with a cotter pin. There are one or two tubes that slip into the gas valve inside the grill. Once you remove the cotter pin the burner will slip out of the gas valve, and you can take the burner with you to purchase your replacement.
Turn off the gas supply valve on the tank. Remove the fuel line from the fuel tank by turning the connection nut counter-clockwise with your hand.
Open the Char-Broil gas grill and remove the main cooking grate. You do not need to remove the upper warming racks to change the burners.
Remove the lava rocks from the grill and pull the rock grate out. Unhook the flame spreader from each end where the spreader attaches to the inside body of the grill. The spreader is the angled piece that sits over the burner.
Locate the cotter pin that secures the front of the burner to the grill body. Remove the cotter pin with a pair of needle nose pliers. Lift the burner up and pull the burner venturi tubes out of the gas valve.
Set the new burner inside the grill with the venturi tubes inside the gas valve opening. Install the cotter pin to secure the burner to the grill body. Place the flame spreader back inside the grill and hook the ends to the grill body.
Place the rock grate, lava rocks and cooking grate back inside the grill. Reattach the fuel line to the fuel tank.
