Designed for emergency home backup portable power use, RV and camping power needs, and as a power source on many DIY home projects, the EF2200iS is the first in Yamaha’s upcoming lineup of generators exclusively equipped with CO Sensor technology to meet the Portable Generator Manufacturers’ Association’s™ (PGMA®) ANSI/PGMA G300-2018 standard to monitor carbon monoxide emissions.

When the CO Sensor detects elevated levels of carbon monoxide, the EF2200iS automatically shuts off and will remain off for approximately five minutes, with indication that the generator needs to be moved to a well-ventilated space.

A new CO Sensor graphic and LED indicator lights on the control panel notify the user of carbon monoxide emission levels or system malfunctions.
