GENERAL MAINTENANCE
• Re-certify 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
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
SETTING INLET TEMPERATURE
• Turn on and zero the analyzer with out the flue probe connected to use ambient temperature
• Connect flue probe thermocouple to T1 during zero countdown to store probe tip temperature as inlet (ducted system)
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 the 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.
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 hold down “On/Off”
and switch off the analyzer. The instrument will count down from 30 to switch
off. If you pressed “On/Off“ by mistake, pressing “Send“ will return you to normal
operation.
EMPTYING & CLEANING THE IN-LINE WATER TRAP
The in-line water trap should be checked and emptied on a regular basis. Water vapor will condense in
the probe line, which may cause the water trap to fill suddenly if the probe is moved. Care should be
taken at all times.
Carefully remove the rubber plug from the bottom of the water-trap housing. Dispose of the condensate
in a suitable drain, care must be taken as it could be acidic. If condensate spills onto the skin or clothing,
clean off immediately using fresh water, seek medical advice if problems occur. Ensure plug is replaced
before performing combustion tests. Note: O2 reading will be high if the Water Trap Plug is not in place.
CHANGING THE PARTICLE FILTER
This is a very important part of the analyzer and should be changed regularly. It prevents dust and dirt
particles from entering the pump and sensors that will cause damage. The filter MUST be changed when
it appears discolored on the inner surface.
NOTE: Take care when inserting
the temperature probes as the
pins are polarized. Insert with the
smaller pin (+) to the right.
NOTE: Do not insert anything
into programming port.
Remove water-trap assembly from the analyzer as shown above. Remove the filter and plastic holder
from the housing. Discard the filter element but keep the holder to fit to the new filter. Clean the inside
of the filter housing with a suitable soft cloth. Fit the holder onto the new filter element and then insert
into the housing. Refit the housing onto the analyzer.

Page 13
REPLACING THE BATTERIES
This meter has been designed for use with both alkaline and rechargeable Nickel Metal Hydride (NiMH) batteries. No other types are
recommended. The analyzer is supplied with 4 “AA” size alkaline batteries. These should be installed into the instrument as shown in the diagram
indicated on the back of the unit.
CAUTION!
Take great care when installing the batteries to observe correct polarity.
Always check the meter for operation immediately after installing
new batteries.
Using Re-Chargeable Batteries
The battery charger must only be used when NiMH batteries are fitted. Alkaline batteries are not re-chargeable. Attempting to recharge alkaline
batteries may result in damage to the product and may create a fire risk.
Battery Charging
Ensure that you use the correct charger. This unit uses a 9V DC regulated charger. Ensure that the batteries are fitted in the correct manner, and
then charge for at least 16 hours. Subsequent charges should be overnight. NiMH batteries may be charged at any time, even for short periods
to conduct testing.
WARNING!
Under NO circumstance should you expose batteries to extreme heat or fire as they may explode and cause injury. Always
dispose of old batteries promptly in a manner consistent with local disposal regulations.
POST TEST
O2% 20.9
COa -0>-
Remove the probe from the flue and allow the analyzer to purge
with fresh air until readings return to zero. - O2 to 20.9%, CO to
Zero (Be careful as the probe tip will be HOT)
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.
ANNUAL RE-CERTIFICATION
Drain water trap by unplugging
the drain plug and shake to
get excess water out.
Check particle filter for dirt
and any other sediment and
replace if necessary.
While the CO sensor has an expected life of more than five years in normal use it is recommended that the analyzer is re-certified 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 they comply with relevant guidelines.
CLEANING
Periodically clean your instruments case using a damp cloth. DO NOT use abrasive, flammable liquids, cleaning solvents, or strong detergents as
they may damage the finish, impair safety, or effect the reliability of the structural components.

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 speed of the 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 in the handset, 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.

ELECTROMAGNETIC COMPATIBILITY (EMC)
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 (January 2015) 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.

available or when recertification is due.We manufacture industry-leading products for professionals like you; please help us to ensure your product is always
fit for purpose by registering your new purchase online - it only takes a few minutes.
IMPORTANT: RE-CERTIFICATION
While the CO sensor has an expected life of more than 5 years in normal use, it is recommended that the analyzer is recertified annually. The C85 analyzer
typically requires an annual recertification each of the first four years and full recertification on the 5th year pending use. This eliminates long term drifting of
the sensor and electronics. Local regulations may require more frequent calibration and users should check with appropriate authorities to ensure compliance.
UEi Test Instruments offers 2 kinds of recertification services.
Annual: Calibration of all installed sensors
Full: Replacement of all applicable sensors
Both services offer:
Full system, 30-point inspection with replacement of any failed parts.
Firmware and/or software upgrades as needed.
Certificate of calibration provided for record keeping.
Recertification work report to document work completed.
Units returned cleaned with paid return freight.
All units are recertified by trained professionals, which eliminate the legal liability of self-installed sensors. In the USA we have two recertification locations, one in Indianapolis, IN the second in Portland, OR. For Canadian customers we have a recertification service center in Vancouver, BC, which is ISO/IEC
17025:2005 accredited and offers NIST certification services for select products. All recertification services are warranted for one year.
