I will run the gen at night if it is extremely hot or my 2 Fantastic fans and inside fan don’t cut it. It will be located at least 10′ away. If there is a predictable prevailing wind then I may run it off my external camper location, that a sepatate sunject! It is very noisey.
Where I live, north of Toronto, it is not really an issue. We only get 2 seasons, winter and August.
