Q6: Why do I still have a CO shutoff if I properly placed my generator outdoors with the exhaust pointing away?
A: Objects close to the generator may trap CO around the generator and cause it to shut off. Make sure there are no objects within 5 feet of the generator. Also, if the generator’s exhaust is facing into the wind, the exhaust may be blown back into the generator’s operating area, causing enough CO accumulation to trigger a shutoff. Try turning the generator 45° in either direction to allow the exhaust to blow away from the generator.
