The Weber Performer grill is a charcoal grill that uses a gas igniter to light the charcoal. This eliminates the need for lighter fluid. The performer grill uses small propane tanks, which are sometimes referred to as propane cylinders or LP (Liquefied Petroleum) gas cylinders. The Weber Performer grill can run on propane or LP gas, and these cylinders are available where camping and grill supplies are sold.
Purchase a 400gr. or 465gr. disposable propane cylinder. Read the label of the tank to ensure that it has a CGA #600 connection, which is necessary to attach it to the Weber grill.
Remove the cap from the top of the propane cylinder by twisting it off in a counter-clockwise motion.
Push the propane tank up into the regulator which is located on the right side of the grill in front of the charcoal storage container. Screw the tank onto the regulator by turning it clockwise until it is tightly secured.
Mix a solution of equal parts dish soap and water in an empty spray bottle.
Turn on the gas supply by turning the gas control counter-clockwise one full turn.
Spray the solution onto the propane cylinder where it attaches to the regulator and along the hose which connects the regulator to the grill. Look for any bubbles which indicate a gas leak. Turn the gas supply off using the gas control knob.
Wipe the area with a wet rag to remove the soap if there is no gas leak. If bubbles did appear and indicate a leak, remove the tank and carefully reattach it to the regulator securely. Check for gas leaks again before you attempt to use the grill.
Contact a Weber Customer Service Representative through the Weber website if you discover a leak in the regulator hose or if leaks around the regulator persist after you have repeatedly attempted to correctly attach the propane cylinder.
