What should flue gas Analyser readings be?
Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance. Generally when this level is below 0.004 the boiler is considered to be running efficiently. For oil or coal fired appliances the CO should not be above 200ppm.

How often should a combustion analyzer be calibrated?
every one to two years
Typically, you should send in your combustion analyzer for calibration every one to two years, depending on what sensors you have. After wear and tear, readings can stray from accuracy. Certain gas sensors have life spans of two years or less, and should then be replaced for accurate measurement readings.
How do you calibrate a Testo thermometer?
Ensure the sensor is completely clean. Before calibration or adjustment, warm the reference oil to approximately 122 °F in hot water. Adjust the measuring instrument with [▲] or [▼] to the TPM value on the reference oil bottle. Confirm with [Hold] to take over the set value.
How long do combustion analyzers last?
between 24 and 36 months
Residential combustion analyzers typically employ electrochemical cell technology sensors, which are used to detect O2 and CO. They usually last between 24 and 36 months.
How much does combustion analysis cost?
Once upon a time combustion analyzers were expensive and difficult to use. Now they are easy to use and can be priced reasonably. But with a range from $500 to over $5000, it is easy to get confused.
Do residential water heaters require a combustion analysis before putting them into operation?
Common home units that should be checked are any appliance that has a power burner (e.g. hot water heater, gas logs, stove, clothes dryer, etc.). A full energy audit should include a combustion analysis on the furnace, water heater, and stoves/ovens.
