It’s easy to keep your Napoleon Grill working efficiently and starting reliably by performing regular maintenance, which includes cleaning the JETFIRE? Ignition and burner ports by using this maintenance kit. Use the brush to clean the electrode tip, and inside the pilot bracket on the JETFIRE? Ignition. The drill bit is for clearing clogged burner ports on our stainless steel burners. Gently, using a small cordless drill, use this tool to remove any debris blocking ports, being careful not to flex the bit.
