If the meter does not indicate any CO in the flue, or the readings are unstable. Do not test in auto or vehicle tailpipes.

UEi recommends annual calibration for flue gas analyzers.

Particle filters need to be changed based on use and the type of fuel. Natural gas burns very clean and will not block the filter fast, while heavy oil and solid fuels will require more frequent changes. Most of our filters will plug from the inside core out, and must be inspected to determine if they need changing. If the inner surface is black from soot it needs to be changed.

This varies by model. Our newer models use IR based sensors with an expected life of 10 years or more. The CO sensors in these newer units have an expected 5 year life. Our traditional electrochemical sensor based analyzers have a one-year warranty on the sensors, with an expected life span of two years.

UEi includes typical test locations and target values as a general guide, but recommends consulting with equipment manufacturers for exact guidelines. We also have available a demonstration DVD that shows the Eagle/EagleX series in use on a variety of equipment. Some of the tests from this video are posted on You Tube.

If you have a second thermometer and water you can compare readings. Connect only the thermocouple connection from the probe, and submerse the tip of your probe in the water. Submerge the second thermometer and then compare readings between that thermometer and the gas analyzer. If the readings are off by 4 degrees or more please return to UEi for calibration. Small variances in flue temperature readings will have very little impact to calculated values of efficiency.

Check the water trap drain plug to veify it is place. Also test the pump flow by briefly blocking the tip of the flue probe or blocking the inlet on the water trap. When blocked you should be able to hear the pump speed change and feel suction from the pump.

When using the standard configuration on these models, the upper limit is 10,000 ppm. Options are available to use on internal compustion where the CO level is measured in percentage and can read to 4% or higher. Please contact UEi for details.

If the analyzer has been in for service to UEi there will be a calibration label with the next calibration due date.

Note - Do not test with automotive tailpipe exhaust. To perform a quick check of the CO use a paper or wood match or small piece of paper. Light the match or paper then extiguish it. Allow the analyzer to draw the smoke into the probe or bottom of the water trap. This should give you a reading of 50~100 ppm if you are able to draw in sufficient smoke. It should then return to zero within 3~5 minutes.

UEi recommends storing in a moderate temperature between 32~100F. If the temperature is expected to drop significantly below freezing or excessivly high it is recommended that the unit be brought inside.
