DISPLAY PARAMETERS ON UEI COMBUSTION ANALYZERS

• TF = Flue Temperature: Calculate net temperature in °F or °C.

- Shows ambient temp after fresh air calibration and ‘-OC-’ when probe is disconnected.

• T = N

∆

• T

• O2 = Oxygen: O2 percentage displayed

• CO = Carbon Monoxide: CO ppm (parts per million) displayed.

• CO2 = Carbon Dioxide:

X = Excess Air:

•

• EFF = Efficiency:

∆ = Loss:

•

CO a = Carbon Monoxide Air-Free: Referenced to an oxygen level of 0%.

•

AMB = Air Inlet:

•

CO/CO2 = CO/CO2 Ratio: The ratio of measured CO divided by CO2.

•

• D = D

• P = Pressure

• NO = Nitric Oxide:

• -PO- = P

• -O>- = High O2 level:

-OC- = Probe Not Connected:

•

et Temperature

- Differential of flue temperature minus ambient (or inlet) temperature

- Differential of T1 - T2

emperature Differential

= T

-‘- - - -’ or ‘- OC -’ is displayed if there is a fault with the CO sensor or

the instrument has not been zeroed correctly, switch off instrument and try again.

- EAGLE (C125 & C127) Calculated from the fuel selected and the measured O2 level

- EAGLE (C125 & C127) Will display ‘- - - -’ or ‘-O>-’ if the O2 level is too

high to calculate CO2 or in fresh air.

- Calculated value is only displayed during the combustion test.

- EAGLE X (C155 & C157) Direct measurement CO2 ppm (parts per million) displayed.

- Indicated as ‘XAIR %’ on the printout

- A calculated percentage of O2 above the theoretical level required for complete combustion.

- Is required to completely burn the fuel due to poor mixing and assisting in venting flue gases

- Only displays a reading during combustion test.

-‘- - - -’ or ‘-O>-’ is displayed in fresh air.

- Calculated based on gas readings, net temperature and fuel selected.

- Value is combustion efficiency, not appliance efficiency.

- Total losses calculated from Combustion Theory. A summation of the next three parameters

• Dry %: Calculated heat lost turning the Carbon in the fuel to Carbon Dioxide (CO2)

• Wet %: Calculated heat lost turning the Hydrogen in the fuel into water (H2O)

• CO Loss %: Calculated loss due to partially burnt Carbon.
Any CO in the flue has the potential to be turned into CO2 releasing and losing more
heat up the flue.

Do not confuse this reading with the actual CO reading as detailed above.

-

- See the Combustion Efficiency Calculation sections for more details.

- Temperature used to calculate the NET temperature.

- It gives an indication of:

• How good a gas sample the instrument is reading.

• How clean the boiler is running.

- Example: A new or clean domestic boiler will display a ratio of less than 0.004, a unit in need
of cleaning 0.004 - 0.008 and a unit needing a major overhaul will show at least 0.008.

- Only displays a reading during combustion test. ‘

SAFETY NOTES

efore using this meter, read all safety information carefully.

B

"WARNING" is used to indicate conditions or actions that may pose physical hazards to the user.
"CAUTION" is used to indicate conditions or actions that may damage this instrument.

ARNING!

W

This analyzer extracts combustion gases that may be toxic in relatively low concentrations. These gases are
exhausted from the back of the instrument. This instrument must only be used in well-ventilated locations.
It must only be used by trained and competent persons after due consideration of all the potential hazards.

PREFLIGHT CHECKLIST

Getting Started

• 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

• Inlet temperature probe is connected if required

ANALYZER CONNECTIONS

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

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. Use the GAS
ZERO function (Eagle X only) to purge the analyzer of excess gases. To do this on a standard Eagle 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.

• 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)
