Why Oxygen Trim Should Be Part of Your Boiler Room – The …

5/9/2019 · Should the oxygen level have a large deviation from setpoint, the control system will alarm and/or shut down the burner before something bad happens. Another safety function of O2 trim is if a very high CO condition is present, the CO will also make the O2 cell read a lower oxygen level and alarm/lockout the boiler.
