He's gotta be talking CO. CO2 should be 9.0-9.5%

the sprint has a ment if its to high all the bells and whistles ,could be fan,flue,co/co2 out of adjustment or heat exchanger gasket

start with basics check the flue if seal between inner and outer tubes on flue is damaged readings will be high as boiler is sucking in exhaust fumes instead of clean air
