start here at the factory site

then snap a few pix of your gen set and post the serial number.

lots of versions of the gen sets for other countries
and it depends on the production run date.

most gens with C/O sensors post this in BIG letters on the gen panel.
and there will be a sensor window vent slits for the intake to the sensor.

 

Thank you.

Does the Champion 100520 8750-watt inverter generator have a co sensor?

No, the Champion 100520 doesn't have a CO sensor. The almost identical WEN model GN875i also does not have a CO sensor, but the GN875iX does have the sensor.

 

Thank you.
