Shut down unsafe equipment immediately
If occupants report symptoms, evacuate the area and advise emergency medical evaluation
Recommend use of functioning UL-listed carbon monoxide alarms
Verify proper venting and chimney draft
Check combustion air settings and smoke
Inspect heat exchanger and flue passages
Never leave an appliance operating with unsafe CO levels
