Page 4: Overview
Nalyzer oNNeCtioNS CoNt WARNING! The probe will be hot from flue gases. Remove the probe from the flue and allow it to cool naturally. Do not immerse the probe in water, as this will be drawn into the analyzer and damage the pump and sensors. Once the probe is removed from the flue and the readings have returned to ambient levels rotate the selector to “OFF”and switch off the analyzer. The instrument will count down from 30 to switch off. -
Page 5: General Maintenance
eNeral aiNteNaNCe • Check calibration of your instrument annually to ensure it meets original performance specifications • Keep your instrument dry. If it gets wet, wipe dry immediately. Liquids can degrade electronic circuits • Whenever practical, keep the instrument away from dust and dirt that can cause premature wear • Although your instrument is built to withstand the rigors of daily use, it can be damaged by severe impacts. Use reasonable caution when using and storing the meter eriodiC erviCe WARNING! Repair and service of this instrument is to be performed by qualified personnel only. Improper repair or service could result in physical degradation of the instrument. This could alter the protection from personal injury this meter provides to the operator. Perform only those maintenance tasks that you are qualified to do. NNual aliBratioN While the sensor has an expected life of more than five years in normal use it is recommended that the analyzer is re-calibrated at least annually, This is so that long-term drift on the sensor and electronics can be eliminated. Local regulations may require more frequent re-calibration and users should check with appropriate authorities to ensure the comply with relevant guidelines. -

This product has been tested for compliance with the following generic standards: EN 50081-1, EN 50082-1 and is certified to be compliant. The European Council Directive 89/336/EEC requires that electronic equipment does not generate electromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. Since there are many electrical products in use that pre-date this Directive and may emit electromagnetic radiation in excess of the standards defined in the Directive there may be occasions where it would be appropriate to check the analyzer prior to use. The following procedure should be adopted. • Go through the normal start up sequence in the location where the equipment is to be used • Switch on all localized electrical equipment that might be capable of causing interference • Check that all readings are as expected (a level of disturbance in the readings is acceptable) • If not, adjust the position of the instrument to minimize interference or switch off, if possible, the offending equipment for the duration of the test At the time of writing this manual (July 2008) UEi is not aware of any field based situation where such interference has ever occurred and this advice is only given to satisfy the requirements of the Directive. -

Page 10: Combustion Basics
COMBUSTION BASICS NtroduCtioN UEi combustion analyzers provide real time data that provides information on the condition of the combus- tion process of your equipment. This information is needed for proper setup and maintenance to verify proper operation. Benefits of combustion analysis are to increase efficiency thus reducing fuel costs, verification of proper combustion to reduce future problems, and to check for safe operation. A combustion process out of balance can increase maintenance needs, create excess emissions, lead to safety concerns or waste fuel and money. -
Page 11: Ideal Vs. Real World Combustion
deal omBuStioN This is When we burn pure hydro- gen in the air. Our atmosphere is 20.9% oxy- gen with the remaining 79.1% nitrogen. This is nearly as desirable as the example for ideal combustion with the only added loss being the heat that is carried away from your target with the nitrogen. Because nitrogen isn’t part of the combustion process, it enters the combustion chamber at the inlet temperature and leaves with some of the heat created by the combustion. If this isn’t recovered at the heat... -

form SO2. There would be no additional air to carry heat away from the fire, and no undesirable byproducts would be created. In practice this isn’t possible due to the inability to completely mix the fuel and air, so an additional amount of air is used to completely burn the fuel. The chart in figure 4 illustrates the relationship between the main flue gas components that provide an indication of the performance of the combustion process. As you move left to right you are going from a rich to lean condition. The term Air rich is equivalent to fuel lean, and simply indicates a situation where the excess air is much higher. To adjust the combustion process you are given the best overall picture of the condition by measuring all three parameters. -
Page 13: Measurment Terms
As an example you would measure the CO2 level and the stack temperature and then reference a slide scale that would give you the relative efficiency number. UEi’s electronic combustion analyzers perform the measurements on a continuous basis, and can calculate the efficiency as adjustments are being made. With this information you are able to provide a before and after comparison of the combustion equipment in relatively little time as part of normal servicing. -

GLOSSARY eleCtor aNd iSPlay arameterS mart “ZeRO” – Analyzer is performing the initial zero setting CO2 (Carbon Dioxide) – Direct reading of the carbon dioxide sensor displayed in percentage Eff (Efficiciency) – Calculated combustion (not appliance) efficiency based on measurements of CO2, Flue Temperature and fuel selected. The SmartBell calculates gross combustion efficiency and automatically determines if the combustion is in the condensing mode to make appropriate corrections. X-Air (Excess Air) – Excess Air is calculated for each fuel type from the CO2 measure- ment. It assumes that the combustion process is running fuel lean. It is important to make other measurements to confirm that this assumption is always correct. -
