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.

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

  • WARNING

    • 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)
  • WARNING

    • 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 must only be used in well-ventilated locations by trained and competent persons after due consideration of all
      potential hazards.

    • 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.

  • NOTE: 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 gas of the test gas.

OVERVIEW

  • The C165+ Combustion Analyzer measures CO, CO2, differential temperature and differential pressure.

  • CO2 is set to zero in fresh air automatically after the initial countdown.

  • It is important that re-zeroing is done in outside fresh air as indoor CO2 levels are affected by human breath.

  • It calculates oxygen (O2), CO/CO2 ratio, Losses, Combustion Efficiency (Gross, Nett, Gross Condensing, or Nett Condensing).

  • The C165+ Combustion Analyzer can also measure CO levels in ambient air – useful when a CO Alarm is triggered. It can also perform a Room CO Test for 30 minute duration.

  • A low flow detection system warns of low flow and switches the pump off. This also helps to prevent water ingress from overfilled water traps.

  • 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 large 6 line display provides the user with relevant information. All data can be printed via the infrared printer or Wireless Printer App.

  • The C165+ uses a new data storage system allowing the user to store the maximum number of logs of interest to them, rather than be restricted to
    an allowance of particular logs.

  • The memory can store up to 45 logs of any combination of Combustion, AUX, Temperature, Heat Exchange, Room CO.

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 the 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.

CAUTION
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 flue probe and 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 the 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

NOTE
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). For these reasons it is very important that the analyzer be in outside fresh air when powered on.

CO OVER-RANGE PROTECTION PUMP

The analyzer’s intelligent protection system will automatically activate the protection pump once an over-gas condition is detected (see specification table for detection limits). When activated the main sampling pump will be shut down, allowing the sample system to be purged with fresh air. Once readings have returned to a safe level, the protection pump will shut down and the main pump will reactivate.

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.
CAUTION!: Ensure the flue probe handle does not get hot!

HEAT EXCHANGE INTEGRITY TEST

There are many methods to test heat exchange 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 pressure increase in the plenum. The result may be a rise in the measured O2 in the stack gas and an increase in 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 there is a problem with the Heat Exchanger which may require additional testing and inspections.
NOTE: Many cracks are invisible to borescopes or the naked eye, and only open or separate from pressure or temperature changes
during operations. Rotate dial to “EXCH TEST” Rotate test selector to “EXCH TEST”. Call for heat on the system. Observe and wait for
O2 readings to stabilize.

ELECTROMAGNETIC COMPATIBILITY

European Council Directive 89/336/EEC requires electronic equipment not to generate electromagnetic disturbances exceeding defined levels and
have adequate immunity levels for normal operation. Specific standards applicable to this analyzer are stated below.
As there are electrical products in use pre-dating this Directive, they may emit excess electromagnetic radiation levels and, occasionally, it may be
appropriate to check the analyzer before use by:
Use the normal start up sequence in the location where the analyzer will be used.
Switch on all localized electrical equipment capable of causing interference.
Check all readings are as expected. A level of disturbance is acceptable.
If not acceptable, adjust the analyzer’s position to minimize interference or switch off, if possible, the offending equipment during your test.
At the time of writing this manual (November 2020) UEi Test Instruments is not aware of any field-based situation where such interference has
occurred, and this advice is only given to satisfy the requirements of the Directive. This product has been tested for compliance with the following
generic standards and is certified to be compliant.

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

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 Net temperature, draft and efficiency.
  • Net Temperature
    Net 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 Net 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, so it will use this temperature when calculating Net 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
      Net 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 air-free. 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
