IMPORTANT SAFETY WARNINGS
Read entire Safety Notes section regarding potential hazard and proper instructions before using this analyzer. In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument. This analyzer must only be used in well-ventilated locations by trained and competent persons after due consideration of all potential hazards.

To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

· Do not use this analyzer during electrical storms or in wet weather. · To avoid false readings, charge batteries if a low battery indicator appears. · Always adhere to national and local safety codes. Use proper personal protective equipment (PPE).
This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are exhausted from the back of the analyzer.
This analyzer is designed for trade professionals who are familiar with the hazards of their trade. Observe all recommended safety procedures that include proper lockout utilization and use of personal protective equipment that includes safety glasses, gloves and flame resistant clothing.
Users of portable gas detectors are recommended to conduct a “bump” check before relying on the unit to verify an atmosphere is free from hazard. A `bump” test is a means of verifying that an instrument is working within acceptable limits by briefly exposing to a known gas mixture formulated to change the output of all the sensors present. This is different from a calibration where the instrument is also exposed to a known gas mixture but is allowed to settle to a steady figure and the reading adjusted to the stated gas concentration of the test gas.

OVERVIEW
The direct measurement of CO2 is achieved using UEi’s own EOS technology sensor. CO2 is set to zero in fresh air automatically after the initial 60 second countdown.
If “ZERO CO2” is indicated, ensure the unit is in outside fresh air before selecting the “Purge” option. It is very important that re-zeroing is done in outside fresh air as indoor CO2 levels are affected by human breath.
The analyzer has a protective rubber boot with magnets for hands-free operation and is supplied with a probe with an integral temperature sensor.
A low flow detection system warns of a low flow and switches the pump off, this also helps prevent water condensate ingress from overfilled water traps.
A large 6 line display provides the user with relevant information based on current activity including instrument status via the new intelligent Status Bar. All data can be printed via an optional infrared printer.
The C161 uses a new data storage system allowing up to 30 logs of any combination of Combustion, AUX or Temperature tests, rather than be restricted to an allowance of particular logs.
10 characters can be added to Line 1 of the header, 6 characters to Line 2 of Header of the printouts.

PRE TEST CHECKLIST

· Clean particle filter · Water trap and probe line are empty of water · Power on and zero · All hose and thermocouple connections are properly secured

· Flue gas probe is sampling ambient FRESH air · Water trap is fitted correctly to the instrument · Flue temperature plug is connected · Ensure water trap plug is inserted correctly

SETTING INLET TEMPERATURE
· Turn on and zero the analyzer without the flue probe connected to use ambient temperature. · Connect flue probe thermocouple to T1 during zero countdown use for inlet ducted system. · Connect a thermocouple to T2 to measure second temp source.

ANALYZER CONNECTIONS
WARNING! Turning the pump off while the probe is in the flue will leave toxic gases inside the analyzer. Once data has been printed or copied, it is advisable to purge the unit with fresh air as soon as possible. To do this remove the probe from the flue and turn ON pump. Always allow the readings to return to zero (20.9% for O2) prior to shutting the unit off. The meter will not switch off until the CO reading is below 20 ppm.

T1

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.

NOTE: Take care when inserting the temperature probes as the pins are polarized. Insert with the smaller pin (+) to the right.

EMPTYING & CLEANING THE IN-LINE WATER TRAP · Remove the rubber plug · Allow the water to drain out · Re-insert the rubber plug
CHANGING THE PARTICLE FILTER · Remove the protective rubber boot · Slide the water trap unit from the analyzer · Remove the particle filter from its’ spigot and replace · Slide the water trap back into position and replace protective rubber boot
QUICK START Turn on the analyzer by pressing the On/Off Button for 2 seconds until the unit activates. As described the analyzer will perform a 60 second turn on purge. Once completed simply select the reading desired by the position of the rotary dial.
FRESH AIR PURGE Each time the analyzer is turned on it will perform a 60 second air purge, this is to clear the gas sampling path (including probe, if connected), and self calibrate the CO2 detection system. For these reasons it is very important that the analyzer be in outside fresh air when powered on.
WARNING When in the Rotary Dial positions AUX, Flue 1 or Flue 2 ; Press the Up or Down Buttons, scroll to CO2 Zero. On the Purge option, short press the Edit Button, and a 60 second Purge will begin.
MEASURING FLUE GASES After the initial countdown is finished and the analyzer is properly setup, put its’ flue probe in the appliance’s sampling point. The tip of the probe should be at the center of the flue. Use the flue probes depth stop cone to set the position. With balanced flues, make sure the probe is positioned into the flue so no air can “back flush” into the probe. NOTE: Ensure the flue probe handle does not get hot!

HEAT EXCHANGER TEST
NOTE: Test results; O2, CO and Excess Air will show on the printout. There are many methods to test heat exchanger integrity. One of these is to observe the Excess Air, O2 and CO readings both before and after the blower turns on. If the heat exchanger is sealed your O2 and CO readings should remain fairly stable. A breach in the heat exchanger may allow fresh air to be forced into the flue after the blower turns on due to a pressure increase in the plenum. The result may be a rise in the measured O2 in the stack gas and an increase in the Excess Air . In some sealed systems the fresh air drawn in through the breach may reduce the combustion air available leading to an increase in the CO reading. If either of these situations are present it is probable that there is a problem with the Heat Exchanger which may require additional testing and inspection.
NOTE: Many cracks are invisible to borescopes or the naked eye, and only open or separate from pressure or temperature changes during operations. Select the Exch Test rotary dial position. Call for heat on the system. Observe and wait for O2 readings to stabilize.

POWERING OFF When you power off the C161, there is a 10 second purge.
Make sure you do not exceed the analyzer’s operating specifications. In particular: · Do not exceed the flue probes maximum temperature (1112°F) · Do not exceed the analyzer’s internal temperature range · Do not put the analyzer on a hot surface · Do not exceed the water trap’s level · Do not let the particle filter become dirty and blocked
View the displayed data to ensure that the stable operating conditions have been achieved and the readings are within the expected range.
POST TEST
Remove the probe from the flue and allow analyzer to purge with fresh air until readings return to zero. O2 to 20.9%, CO to Zero (Be careful the probe tip will be HOT).
GENERAL MAINTENANCE · Re-certify your instrument annually to ensure it meets original performance specifications.
PERIODIC SERVICE 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.
· 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.
COLD WEATHER PRECAUTIONS It is important you keep your flue gas analyzer in a warm and dry place overnight
Electronic devices that become really cold, by being left in a vehicle overnight, suffer when taken into a warm room the next morning. Condensation may form which can affect the analyzer’s performance & cause permanent damage. See operating and storage temperature specifications.
Electrochemical sensors used in flue gas analyzers can be affected by condensation or water being sucked into the analyzer, as the small apertures on top of sensors can become blocked with water, stopping sensors seeing flue gas. When this happens, oxygen or carbon dioxide reading will display as “–” & sensors may be permanently damaged
If you think that your analyzer is affected by condensation or water ingress, it may be possible to rectify the problem yourself. Simply leave the analyzer running in a warm place, with the pump `ON’ sampling fresh air for a few hours (use mains adapter/battery charger if needed). If, after doing this, you still experience problems please contact our Service Center.

OTHER IMPORTANT FACTORS RELATING TO COMBUSTION
The three T’s of combustion · Time: Amount of time that the fuel and oxygen are together in the combustion chamber · Temperature: How high the temperature is determines the rate of oxidation, or spread of combustion · Turbulence: How well the fuel and air are mixed These three factors are all interrelated and will move your results along the combustion curves.
COMBUSTION MEASUREMENT TERMS
Other parameters measured include Nett temperature, draft and efficiency. Nett Temperature Nett temperature is the difference between the combustion air entering the combustion chamber and the flue gas temperature past the heat exchange. This is used to determine how efficient the system is extracting heat from the combustion process in addition to the performance of the combustion process. On sealed systems that have ducted inlet air for combustion air, the Nett temperature must compare this air stream temperature with the flue gases. If the appliance simply uses room air for the combustion air, our analyzers have an internal temperature sensor in the handset, so it will use this temperature when calculating Nett temperature. The most accurate results for efficiency are obtained when measuring flue gases at the point where flue temperature (not flame temperature) is the highest.
Draft Draft is the difference between the ambient pressure level and the pressure level in the flue. This is created either by the natural buoyancy of the hot gases created in combustion lifting, or by an inducer fan that assists the flow of flue gases up the stack. Most combustion equipment will specify the amount of draft that is required for proper operation. Draft helps draw combustion air into the combustion chamber, and also helps in mixing the fuel and oxygen. Without proper draft, the combustion process can spill poisonous by-products into the space where the appliance is located. This can be a risk to those in the area, or create a danger to residents or employees working near the combustion equipment.
Efficiency Efficiency is a measure of how well the fuel is burned to create heat, and how well the generated heat is captured for the intended use. The information used to create this value are based on the fuels heating value, the heat lost up the flue and the gas components in the flue gas. The original method to determine efficiency included many manual methods and lookup charts. 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. Combine this with a printout and you are able to provide a before and after comparison of the combustion equipment in relatively little time as part of normal servicing. Combustion efficiency is not the same as AFUE (annual fuel usage efficiency). AFUE is not measurable with any portable flue gas analyzer.
Combustion Efficiency Calculations This identifies three sources of loss associated with fuel burning:
· Losses due to flue gases: Dry Flue gas loss, Moisture and hydrogen, Sensible heat of water vapor, Unburned gas
· Losses due to refuse: Combustible in ash, riddling and dust
· Other losses: Radiation, convection, conduction other unmeasured losses
Nett efficiency calculations assume that the energy contained in the water vapor (formed as a product of combustion and from wet fuel) is recovered and the wet loss term is zero. Gross efficiency calculations assume that the energy contained in the water vapor is not recovered. Since the fuel air mixture is never consistent there is the possibility of unburned/partially unburned fuel passing through the flue. This is represented by the unburned carbon loss. Losses due to combustible matter in ashes, riddling, dust and grit, radiation, convection and conduction are not included.
CO Air Free Certain standards ( ANSI Z21 .1) for Carbon Monoxide are stated in terms of air-free . Air-free refers to the concentration of CO in combustion gases undiluted with flue, or other gases containing little CO . This value is computed using an equation that takes into account the O2 concentration of the flue gas .
· If 5% O2 is measured (O2m) in the flue then the CO gas value will be recalculated as if 0% were measured . The equation for air-free is as follows:: COaf = CO PPM x [(20 .9) / (20 .9 – O2m)] · In our example if a reading of 325 PPM were measured then the air-free value would be calculated as follows: COaf = 325 PPM x [(20 .9) / (20 .9 – 5)] COaf = 325 PPM x [(20 .9) / (15 .9)] COaf = 427
We may be given a limit on our gas range by the local authority, which stated that we must not emit more than 400-PPM Carbon Monoxide airfree . In the example we would be breaking the limit and corrective action should be taken to reduce the level of CO . Air-free values prevent false readings being submitted, e .g . allowing more air into the boiler will increase the oxygen level in the flue and dilute any toxic gas reading . Air-free referencing gives readings as if they were undiluted .
