2 GENERAL

2.1 Keypad & Display

The tactile keyboard allows the operator to enter the main operative mode and all other complementary or auxiliary modes following the menu driven instructions. The high contrast graphic LCD (40x56 mm), equipped with an automatic back-light device, displays the measured and/or calculated parameters in the preferred format (Zoom function). The above parameters can be also displayed in a graphic mode.

2.2 Built-in printer

EGA4 can be equipped with a built-in, rugged, impact type printer. It uses a low cost common roll of paper (58 mm large, 18

meters long) , more readable, long time and heat resistant better than the thermal printout on chemical paper. One key instruction is enough to obtain one, two or more copies of the analysis report with header and company reference data.

2.3 Gas sampling probe

Flue gas sampling probes with different length, shape and max. operating are available to match the requirement of different applications. The sampling probe is connected to the instrument with a rubber hose through a combined module of water trap and suspended particle filter.

2.4 Measuring sensors

EGA4 uses long life sensors for O2, CO (H2 compensated), NO, NO2 and SO2. An automatic internal device diluted the CO

concentration when a high level of CO is identified by the instrument. Dilution system allows to extend the measuring range of the CO sensor up to 10%. The optional Autozero valve for quick start-up allows the operator to switch the instrument with the gas probe in the stack. Four acoustic and visual alarms can be set on four programmable parameters.

2.5 Temperature probes

A thermocouple type K is incorporated on the tip of the gas sampling probe to measure the flue gas temperature. This thermocouple is suitable for measurements up to 800°C (max 1000°C for few seconds). Temperature measurement and gas sampling from the flue gas pipe are thus always performed in the same site. The probe is connected to the instrument with the appropriate compensated cable and connector. A Pt100 resistance thermometer (local jig or remote sensor) is used for the air temperature measurement and best efficiency calculation.

2.6 Pressure sensor

The instrument is equipped with an internal sensor for pressure and stack draught. One key instruction move the operative mode to and from this function to gas analysis and viceversa. The instrument has, as standard feature, a differential pressure sensor.

2.7 Fuel technical data

The instrument includes as standard the technical data for 4 of the most common fuels. Using the optional GasConfig software, it is possible to modify or add data of up to 10 different fuels.

Page 10

Instruction Manual MM850481 ed. 03a

2.8 Smoke measurement

Smoke index measurement is done by using a hand pump (supplied as an accessory), the results cam be memory stored and printed in the report.

2.9 Remote temperature probe

A remote Pt100 probe is available for combustion air temperature measurement from –10°C to 100°C. This probe is strongly recommended mainly in forced air boiler to obtain an accurate calculation of the efficiency.

2.10 Ambient CO probe

Optional probe to monitor CO concentration and therefore safety condition in the boiler room. The instrument gives acoustic and visual alarm if the set limit (according to the OSHA recommendation) are exceeded.

2.11 Natural gas probe

Optional probe to monitor CH4 and natural gas concentration and detect and locate the position of a gas leak into the domestic pipe network.

2.12 Leak test procedure

To check gas network tightness using a pressure decay method at programmable interval time. It uses the internal pressure sensor and a Eclipse leakage procedure.

2.13 Burner pressure probe

A 1 meter 8x4mm silicon hose (cat. EE300088) is used to check the pressure inside the burner when you are installing the heating system.

2.14 Pitot tube

The EGA4 analyzer can be connected to a Pitot tube for gas speed measurements.

2.15 CO Dilution

This feature helps you to measuring high concentrations of the CO gas and to protect the CO sensor, even for highly polluted environmental. The process dilute the CO concentration that goes on the CO sensor with fresh air, breathed in by a little built-in pump. (see par. 7.2)

2.16 Calibration certificate

Each EGA4 portable gas analyzer, is factory calibrated and certified against Eclipse Standards, that are periodically certified by an International recognized Laboratory, and shipped with a Report of Calibration stating the nominal and actual values and the deviation errors.

Instruction Manual MM850481 ed. 03a

3 PHYSICAL DESCRIPTION

The EGA4 portable analyzer consists of a rugged and compact case, a mother board with all base function circuits, 2, 3 or 4 electrochemical cells, a gas pump, a keyboard, an LCD backlighted display, a Li-Ion rechargeable battery pack and, optionally an impact printer. The 2 pieces of the case are jointed by 8 screws. The batteries, the pneumatic circuit and the cells are positioned in the rear of the analyzer and 2 screws locked the lid. A pressure lid allows to remove the paper roll.

4.1 Measurement principle

The gas is sampled and aspirated through the probe with a primary pump powered at constant voltage. To position the sampling probe in the exhaust gas pathway a hole of 11mm, up to 16mm, should be drilled and the retaining cone of the sampling probe firmly screwed in it. The retaining screw in the cone enables the probe to be easily moved to locate the core flow, normally correspondent to the center of the section of the smoke tube. The flue gas and exhaust gas pathway, should be checked for gas-tightness before carrying out a measurement and, if necessary, non gas-tight points should be sealed.

sensor is essentially an electrochemical cell, with two electrodes and electrolyte solution. The behavior is similar to a

The O

normal battery and therefore the sensitivity decreases with time. The expected life does not relate to the operative time and is lost after approximately 24 months. The toxic gas measurements (CO, SO

The electrochemical cell grants accurate results for time intervals of approximately 60 minutes. The zero drift is automatically corrected by the instrument every time the instrument is switched-on, using fresh ambient air as reference. This operation should be made with the sampling probe not inserted in the chimney or with the sampling probe pneumatic connector disconnected from the analyzer gas inlet. When a long time analysis has to be made, a new autozero procedure should be performed. The pressure/draught sensor is based on the principle of the extension metric measuring bridge. When the instrument is switched-on, a zero calibration of the draught/pressure circuit is also executed. Leave open the “'P” connector during this phase. Measured and calculated parameters are indicated on a LCD alphanumeric display (40x56 mm), equipped with a automatic back light device for easy readings, also in poor light conditions.

, NO and NO2) use electrochemical cells, with an expected operative life of 3 years.

Instruction Manual MM850481 ed. 03a

4.1.1 Gas sampling probe

The sampling probe consists of a steel tube and a handle of thermoinsulating material. A positioning cone allows to place the probe in holes with a diameter from 11 to 16 mm. The gas temperature is acquired using a thermocouple type K with the junction placed on the top of the tip.

4.1.2 Water trap & line filter

The gas flows through an external combined water trap and line filter to avoid the presence of condensation and suspended solid particles in the analysis section of the instrument. A cylinder is positioned at 15 cm from the instrument gas inlet it is divided into two parts: the water trap and the line filter.

The water trap works using the expansion principle: the gas flow decreases its speed inside the cylinder and it will cool; the humidity will condense and the solid particles fall down. The section of the water trap must be periodically drained off to avoid water from entering the analysis section. Pull the rubber plug and shake slowly the trap to drain the water. Push the rubber plug to close the trap hole.

The line filter is positioned after the water trap and before the electrochemical cell. Its function is to stop the smallest solid particles before the analysis. Remember to change the filter every time it is dirty.

Rubber plug cat. EE650081

WARNING

THE WATER TRAP MUST BE KEPT IN VERTICAL POSITION DURING GAS SAMPLING.AN INCORRECT POSITIONING OF THE TRAP CAN ALLOW

THE WATER TO ENTER INSIDE THE ANALIZER AND DAMAGE THE ELECTROCHEMICAL SENSORS.

NEVER MAKE ANY ANALYSIS WITHOUT THE DRAINING RUBBER PLUG. THE MEASUREMENTS WILL BE INCORRECT.

WHEN YOU FINISH THE ANALYSIS, REMEMBER TO DRAIN THE WATER TRAP.BEFORE PUTING THE GAS PROBE IN THE CARRYING CASE,

REMUVE THE CONDENSATE WATER FROM THE PROBE HOSE.

THE LINE FILTER SHOULD BE REPLACED WHEN DIRTY.NEVER MAKE ANY ANALYSIS WITHOUT LINE FILTER AND/OR WATER TRAP, AS IT

CAUSES AN IRREVERSIBLE DAMAGE TO THE ELECTROCHEMICAL SENSOR.

4.1.3 Gas sensors

The analyzer uses long life sensors for O2, CO (H2 compensated), NO, NO2 and SO2. The sensor do not need special maintenance but must be replaced after the expected lifetime. However a full maintenance and certification of the instrument is recommended at one year interval. The gas sensors are electrochemical cells composed by two electrodes (anode and cathode) and an electrolyte solution. The sampled gas goes trough a selective diffusion membrane.

Page 14

Instruction Manual MM850481 ed. 03a

The oxidation process produces an output electrical signal proportional to the gas concentration. The signal is evaluated by the electronics, converted to digital, processed by the microprocessor, displayed and printed with a 0.1% volume resolution. The flue gas must not be at a pressure that could damage or destroy the sensor. Measurements are always carried out under "pressureless" conditions. The maximum permissible excess/reduced pressure is ±100 mbar. Each sensor has a different response time:

CO (H

comp.) = 50s to 90% of reading

20s to 90% of reading

CO = 50s to 90% of reading NO = 40s to 90% of reading NO

OTE:TO OBTAIN AN ACCURATE MEASURE IT IS RECOMMENDED TO WAIT 3/5 MINUTES.

50s to 90% of reading

= 40s to 90% of reading

Toxic gas sensor can be present a ±2% drift and a long resuming time it an excessive (>150% of F.S.) gas concentration is applied. In that case it is recommended to wait for a measured value lower than 20ppm, by sucking fresh air before switch the analyzer off. An optional Electro-valve can be installed inside the instrument to exclude/include manually or automatically the CO cell when the CO concentration is too high (e.g. when the burner is starting) Four acoustic and visual alarm levels can be set on four programmable parameters.

4.2 Auxiliary measurements

4.2.1 Temperature measurements

The instrument is equipped with two temperature inputs to measure exhaust gas and the burner air input temperatures (combustion gas).

i A thermocouple type K (nickel-nickel chromium) is included in the tip of the gas sampling probe to measure the flue

gas/exhaust gas temperature. This thermocouple is suitable for permanent measurements at temperatures up to 800°C

and for short-term measurements up to 1000°C. Temperature measurement and gas sampling from the flue gas pathway are thus always performed at the same site. The probe is connected to the apparatus with compensated cable and connector. An internal Pt100 resistance thermometer is used for cold junction compensation.

i The same Tc K input can be used to measure the flow and return temperature

in water circuit. If you have to measure

the water temperature measuring the pipe temperature, use an arch-model thermocouple with an appropriate diameter.

i A remote Pt100 sensor, can be supplied on request with a 2 or 5 meter cable to measure the air inlet temperature

forced air boiler. This option is very important for an accurate efficiency calculation.

4.2.2 Pressure and Draft

The analyzer can be equipped with a temperature compensated pressure sensor to measure the chimney draft or pressure. The pressure range is from -40 hPa to +200.0 hPa)

The sensor is factory calibrated and does not require manual adjustment. The zero drift, caused by ambient air temperature variation, is automatically cancelled at each instrument start-up. In addition, for more accurate readings the operator can reset, using the pertinent key, the zero if required. The instrument sensor is differential type and, if connected to a Pitot tube, it can be used to measure gas speed.

OTE: WE SUGGEST TO EXECUTE THE AUTOZERO PROCEDURE FOR MORE ACCURACY BEFORE PERFORM THE MEASUREMENT.

CAUTION

4.2.3 Smoke index measurement

This method consists of taking a gas sample from the center of the gas pipe behind the heat exchanger and crossing it through a special filter paper. The color of the spot on the filter is compared with a graduated (from 0 to 9) reference scale and it is called “smoke index”. You can type in the instrument up to 3 smoke index values; the analyzer calculate the average value and can print these values on the report. Normative and laws about the air pollution, describe the procedure: DIN51402, 2116, 2117 and 2297 VDI directives, ASTM D 2156-63 T, etc.

4.2.3.1 Measuring instruments (option)

1. Smoke pump: it should suck 5.75 litres r0.25 l (normalized to 0°C, 760mmHg) through a 1 cm2 filter.

2. Smoke index reference table: it is a grey scale sheet with 10 different areas numbered from 0 to 9. The number 0

corresponds to a 85% r2.5% reflection. Every area reflects 10% less than the previous one. The scale is used to compare the scale with the paper filter and to calculate the smoke index.

3. Paper filter: When it is clean it has a reflection corresponding to the 0 scale index. It also has 3 litres per cm

(normalized to 0°C, 760mmHg) with a 200/800 mmwc resistance to the air flux.

5 RECOMMENDATIONS

 The analyzer should be used in environments where the temperature is between -5°C and +45°C.  When the analysis are completed, before switch the instrument off, remove the probe from the gas pathway and wait

about 30 seconds cleaning the pneumatic circuit from gas.

 Do not use the analyzer with clogged filters or filled with humidity.  Before placing the probe in the case, be sure that the probe, the water trap and the hose are clean and cold.  If you have ordered a double hose sampling probe, insert both connectors to the instrument during the gas analysis (pay

attention to color correspondence).

 To empty the water trap from the condensate water, remove the draining plug. DO NOT OPEN the water trap. DO NOT

leave the water trap without the draining rubber plug.

 For the best efficiency and accuracy, we suggest to calibrate the instrument every year.

WARNING

IF THE EGA4 IS STORED AT TEMPERATURE EXCEEDING THE OPERATIVE LIMITS, THE ANALYZER NEEDS SOME MINUTES TO WARM-UP TO

THE ACTUAL AMBIENT TEMPERATURE, BEFORE STARTING THE OPERATION.

6.2 Gas probe positioning

The measurement site should be arranged at a distance of 2xD behind the exhaust gas connection pipe, where D = diameter of the exhaust gas connection pipe. To position the sampling probe in the exhaust gas pathway a hole of 11/16mm should be drilled and the retaining cone of the sampling probe firmly screwed in it. The retaining screw in the cone enables the probe to be easily moved in order to locate the core flow, normally correspondent to the center of the section of the stack. The flue gas and exhaust gas pathways, must be checked for gas-tightness before carrying out a measurement and, if necessary, non gas-tight points should be sealed. To locate the gas core flow, insert progressively the sampling probe and read the maximum value of temperature.

7.3 Pressure/Draft measurement

If the internal pressure sensor is installed (Table E=2 on ordering code), you can execute the pressure/draft measurements using or the standard probe or the special probe.

Standard probe (TG models):

The standard probe has a single gas collector for gas sampling. Usually you have the hose terminal connected to the instrument gas inlet; when you have to do the draft measurements you have to move the connector to pressure inlet (P IN) connector.

CAUTION

IF A SINGLE TUBE GAS SAMPLING PROBE (TG MODEL) IS USED FOR PRESSURE/DRAFT MEASUREMENTS, BE SURE THAT PROBE AND HOSE

ARE CLEAN AND DRY BEFORE CONNECTION TO THE PRESSURE INPUT.

Special draft probe (TGD models):

This special probe model has a double gas collector: one for the flue gas analysis and one for the draft measurement. When you connect the probe to the analyzer you have to insert both gas inlet and pressure inlet connectors. Connect the hose with line filter to gas inlet connector.

 The pressure measurement requires the instrument in normal operating conditions indicating one of the measured or

Using the burner pressure probe, it is possible to measure the pressure on the burner. Connect the probe to the instrument pressure input and connect to the burner plug. Follow the procedure described in paragraph 8.4 to read the pressure.

7.4 Smoke measurement

To avoid condensation inside the smoke pump, it should aspirate ambient air before the gas sample. This can be obtained aspirating the air by the fireside (not in the exhaust gas connection pipe) without using the paper filter. Introduce now the filter in the pump. The gas sample should be drawn to the center of the combustion gas flux. The correct gas volume is sampled with 10 uniform shoots by the pump. Compare the darkening of the filter with the smoke index table. The smoke index found does not exceed the ones defined by the current normative. We suggested to use a retaining cone during gas sampling.

COPY

It is important to measure the true combustion air temperature to have a correct boiler efficiency computation. The EGA4 has a auxiliary Rtd input to measure simultaneously the air temperature. A Pt100 with a 6 meters long cable can be connected on the right side of the analyzer. Insert the Rtd inside the air combustion aspiration tube and near the boiler. Follow the standard procedure to make measurements. The instrument will show the temperature on the display and the efficiency will be calculated using this value. If no external Rtd is connected, the analyzer will measure the instrument temperature (ambient) using the internal sensor.

7.6 Flow/Return temperature measurement

10 MAINTENANCE

The EGA4 analyzer has been developed and manufactured using high quality components. A correct, systematic maintenance will prevent damage and will increase substantially the life of the instrument, giving excellent results. Anomalous conditions that require extraordinary maintenance interventions are promptly displayed, either clearly or with an information code.

10.1 Water trap

Always keep in vertical position the water trap to avoid that the water condensation inside the trap could flow to the measuring sensors. For the same reason remember to periodically empty the trap and always at the end of the measurement. To empty the expansion vase remove the cap (code EE650081) and gently shake it. Please be sure to

reinsert the cap before the measurements.

Just after the trap you can find a replaceable low porosity line filter (code EE650074). It hold le solid particles of the gas. We recommend you to replace this filter is it's dirty. To replace the paper filter open the trap gently rotating the two trap parts.

Line Filter cat. EE650074

Cap cat. EE650081

!! ATTENTION !!

DON'T MAKE MEASUREMENTS WITHOUT THE TRAP CAP.IF THE CAP IS NOT MOUNTED ON THE TRAP YOU WILL HAVE AN AMBIENT AIR INPUT

INTO THE PNEUMATIC CIRCUIT THAT WILL GIVE YOU WRONG MEASUREMENT VALUES,

CONTROL AND EMPTY, AT EACH MEASUREMENT, THE WATER IN THE TRAP IF PRESENT.PUT THE TRAP IN HIS CASE AFTER EMPTYING THE

CONDENSATION FROM BOTH THE TUBE AND THE EXPANSION VASE ONLY.

TO OPEN THE TRAP GENTLY ROTATE THE TWO PARTS. DON'T PULL. DON'T TWIST.

REPLACE THE FILTER IF IT'S DIRTY OR HUMID. DON'T MAKE MEASUREMENTS WITHOUT THE FILTER OR WITH A DIRTY FILTER: THIS WILL

DAMAGE THE SENSORS IN A IRREVERSIBLE WAY.

CLOSE WITH CAUTION THE WATER TRAP TO AVOID THE FILTER DAMAGING.

10.2 Error messages

The instrument performs the autodiagnostic procedure when switched on. When measuring it checks also for anomalous conditions. If analyzer founds trouble, it display a message on LCD. Sometime these messages corresponds to a unrecoverable problem and it is necessary to return the instrument to Eclipse for maintenance. Frequently these message are referred to a recoverable trouble and can be solved by yourself. The following table show the possible instrument error messages:

10.5 Smoke pump maintenance

Gas-tight checking

To have a correct measurement the pump should be gas-tight. Turn the screw and close the probe with your finger. Pull the plunger for 3 cm and verify that the gasket does not leak the vacuum. If a leak is found the gasket needs to be lubricated. When you push the plunger the valve must close immediately to have a 1.9/2.0 litres of air with 10 shoots. The correct smoke index can be obtained only if the pump works correctly.

Service

1. Clean and lubricate the cylinder, the stem and the gasket every 30 measurements.

2. Wash using alcohol if the valve is not gas-tight

3. Clean the probe and the paper support

4. Check the pump for gas-tight

5. Use only clean paper filters and a readable scale index table
