• To verify that equipment is operating as the manufacture designed it to work. This includes installation
tests for CO, CO2, O2, Excess Air and stack temperatures
- A properly tuned combustion appliance will perform better, and reduce the likelihood of
call-backs for no-heat
• To verify that the maintenance work performed has corrected the problem
- A print-out documents the before-after improvement in performance
• To detect any defects early – possibly at installation
- Higher efficiency equipment is running at peak only when properly adjusted. As the complexity
of a system increases, so does the importance of proper adjustment of the combustion process.
• Improperly adjusted equipment not only fails to meet expected performance but could lead to future failures
- High CO readings throughout the burner operation could be from a burner that isn’t aligned or
a flame impingement problem
• To check that the equipment is supplied with enough combustion air, make-up air and has proper
venting to exhaust the combustion by-products
• To determine if emissions are within acceptable levels. Governing organizations such as the AGA have
various requirements such as a 400 ppm CO Air Free reading on gas range oven vents
• To check heat exchangers for cracks.
- A breach in the heat exchange may result in CO, O2 and Excess Air values that change after the
blower turns on. This is due to an introduction of additional fresh air into the stack gases from
the positive pressure pushing fresh air into the flue. The Eagle II and III have a test procedure
programmed into the instrument that allow you to capture these values and printout a
comparison of the before and after levels. A change in these values warrants a further look
into the problem
• To monitor the operation during start-up and shutdown.
- Many problems with burners may show an increase in CO at these points earlier than when the
equipment is at operating temperature. A slight rise in CO during these times may be typical,
but anything over 400 would indicate a problem.
• To establish a base-line of desired performance
- By tracking the performance over time you are able to see changes before they lead to
equipment failure.

• Equipment that is not properly adjusted, or that has insufficient draft to vent combustion gases could
produce carbon monoxide in deadly quantities. The UEi Eagle Series test both flue gas and ambient
levels of carbon monoxide. A specific test is programmed into the Eagle II and Eagle III to measure
CO levels over a 30-minute period, and provides a printout to document your test results.
• When customers complain about fumes it is usually an indication of improper operation. CO is a
colorless, odorless gas so the fumes are not the CO, but an indication that a problem may exist.

• The UEi Eagle combustion analyzers give a quick, continuous readout of the combustion process.
Readings change in real-time as adjustments are made to help zero in on the proper setting. Compare
this to spot tests or other methods, and you will see your productivity rise.
• Proper testing with documented results will help you provide the proper service or equipment replacement
recommendations, and have the data to support this. Sales will increase because you are no longer
guessing, and the work provided is proper for the needs of the customer.
• Customers on a service contract will be provided excellent service, and you will quickly diagnose failures
and help keep the equipment up for the season.
