Stop trying to talk like Burr . Be your own damn man <| sep |> Are the original grills made of cast iron ? If yes cover them in vegetable oil . Wipe the excess with a tissue and turn on the gas under it until they smoke . You want to reach the burning point of the oil . After every use wipe out any remaining liquid on the grills because they will eventually create rust , then put some other oil . Every two o three months burn again the oil . It will create a patina who will protect the cast iron that is slighty pourous . <| sep |> long story shortif you know routing and switching , with that setup , you can just feel your way through ASDM . Probably want to look at some access rule examples , but other than that , it ' s not complicated .
