If that's the way your tool reds CSV I suggest you find fome other tool, but as per your question, you may append dummy lines in the following way: Suppose you have a list of names and their phone numbers, returned by this fictious query:
Select PersonName, Phone From MyPhoneBook
You could add your 2 dummy lines in the following way:
Select '' AS PersonName, '' AS Phone
UNION ALL
Select '', ''
UNION ALL
Select PersonName, Phone From MyPhoneBook
