Be very careful leaving the compartment door open as well. I can attest to the fact that things in the wind can find their way into the bottom side of the generator and take out the cooling fan. I had a rag get caught up in my from somewhere last summer while setup with the compartment door open, sitting inside when generator shut off, code showed unexpected shut down. Onan dealer found rag in generator. $650.00 dollar lesson. They are designed to stay closed, the generator is a combination air and oil cooled, high heat does not hurt them.
