What is the ideal O2 content of flue gas?
In residential furnaces, optimum fuel-air ratio results in the oxygen level being reduced from 21\% (fresh air) to between 8.5-10\% oxygen by volume after combustion. To test the oxygen level, a tool called a combustion analyzer is used to measures the amount of oxygen remaining in the flue exhaust gas.
How does an O2 analyzer work?
An oxygen analyzer measures the para-magnetism of air. The air being measured for oxygen is filtered by passing it through a diffuser before. Then it is passed through the two chambers. One chamber attracts oxygen via its magnetic field, while the other chamber attracts air.
How do I control my O2 boiler?
An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply.
What is O2 boiler?
Oxygen trim (O2 Trim) is a system that constantly monitors your boiler’s combustion. Unlike your car, your boiler has the ability to run properly without it, so what are the upsides to it?

How does a CO2 analyzer work?
The CO2 Analyzer use multi-component analysis by using Non Dispersive Infrared (NDIR) sensor technology for consistent, precise process gas measurement. The detector measures these two signals and their difference is proportional to the amount of absorbing gas in the sample cell . i.e. CO2 gas.
How do you calibrate an oxygen analyzer?
Press and hold the Cal button on the Oxygen Analyzer for at least 3 seconds to activate calibration. The Analyzer will detect a stable Sensor signal. When obtained, the Analyzer will display the assumed calibration gas on the LCD.
What is meant by the term oxygen trim control in boiler operation how it is performed?
Oxygen trim (O2 Trim) is a system that constantly monitors your boiler’s combustion. This system can adjust your air fuel ratio based on what it’s supposed to be and triggers alarms or lockouts should the combustion deviate from proper levels. It also helps end users save on operational and maintenance costs.
What causes high CO readings?
Possible Causes of High Carbon Monoxide (CO) Emissions Fuel can only come from three sources: the crankcase vapor control system, the evaporative control system, or the actual fuel delivery system.
