Regular maintenance, including cleaning the JETFIRETM Ignition and burner ports using this care kit, makes it simple to maintain your Napoleon Grill operating effectively and starting reliably. On the JETFIRETM Ignition, use the brush to clean the electrode tip and the interior of the pilot bracket. For our stainless steel burners' blocked burner ports, use the drill bit. Use this device to gently remove any obstructions from ports using a small cordless drill, taking care not to bend the bit.
