Introduction
Thank you for purchasing TPI brand products. The TPI 709 Flue Gas
Analyzer is a state of the art, easy to use analyzer designed not only to display and calculate the required readings from a flue but also to cover most of the other measurements associated with combustion.
The instrument is ruggedly constructed and comes with a 3 Year unit and 2 Year sensor Guarantee.
General Overview
The TPI 709 combustion analyzer uses state of the art electrochemical sensors. This sensor technology provides the longest lasting, most accurate and reliable means for performing combustion tests. The sensors in your analyzer will need to be replaced periodically and calibration is recommended once every year. The 709 will remind you when calibration is due by flashing “CAL DUE Err” for three seconds at start up.
Electrochemical sensors by nature are always active. Therefore the time the analyzer is off and not being used must be taken into account when determining sensor life. The sensors in your analyzer are warranted for two years. This warranty does not cover sensors damaged through misuse of the analyzer.
You should keep the batteries of your 709 fresh so power is constantly being supplied to your sensors.
The following guidelines will help prevent damage to your sensors:
Always use the mini pump filter when testing flue gases.
Always periodically check and replace the mini pump filter as needed.
Always make sure the in-line filter / water trap is installed properly.
Always periodically check and replace the in-line filter as needed.
Always remove water or condensation from the inside of the in-line filter / water trap assembly prior to performing tests.
Always use the optional oil filter (p/n A773) when performing tests on oil burning equipment.

COMBUSTION ANALYSIS OVERVIEW
Performing combustion analysis is very important to the overall safety and efficiency of heating equipment. The following guidelines and descriptions are generic and meant to provide you with a basic understanding of combustion testing. TPI always recommends you contact the manufacturer of the device under test, obtain information specific to the device, and follow the procedures and safety guidelines for performing tests and affecting repairs.
In general, for most applications, flue gas samples should be taken prior to the draft diverter or any other opening that allows room air to enter the system. This prevents room air from mixing with gases in the flue and diluting the test sample. To ensure accurate and consistent combustion tests, it is important gas and temperature samples be taken at the same location. This is easy with the TPI flue probe because the temperature sensor is an integral part of the probe.
Prior to taking a sample, the device under test should be on and operating.
Putting the flue probe in the sample area prior to starting the device may cause saturation of the sensors due to the higher initial concentration of carbon monoxide that may be encountered upon start up. If this happens, allow your analyzer to purge in fresh air until the carbon monoxide level returns to
0 ppm and the oxygen level returns to 20.9%. This may take more than an hour depending on how saturated the sensors are.
The figures on pages 13 through 15 show locations for performing tests on commonly encountered equipment. Remember to consult with the manufacturer of the device under test for specific test information.
Pressing the Func Key enables access to the different functions available on the 712. The default function is Combustion Analyzer. Other available functions are: Thermometer, Manometer/Tightness Test, Combustible Gas Leak
Detector, and Date / Time display.
Refer to the Appendix G “Technical Notes” for additional information.

4. Insert the flue probe into the sample hole of the device under test. The probe tip should be in the middle of the flue pipe or exhaust stream.
Ensure the In-Line Filter / Water Trap hangs below the analyzer in the proper vertical position when readings are being taken. Failure to comply reduces the effectiveness of the water trap and may result in damage to the instrument. Refer to the pictures below for correct and incorrect use.
16
WARNING: - Should the CO reading rise above 2,000ppm a continuous series of Alarm Beeps will be heard. The Probe should immediately be disconnected from the instrument and the instrument returned to a clean air environment.
This Alarm alerts the user that there is a high concentration of CO, and this procedure will protect the sensors within the instrument. The alarm level can be changed. Please see Appendix D
Make sure to check the water trap periodically during testing to ensure it does not fill with condensate and empty it as necessary. If the filter begins to fill during a test, open the lid and empty out the condensate. After closing the lid, allow readings to stabilize again.
IMPORTANT: The water trap is fitted with a water block filter (p/n A794W) in the lid to prevent water from flowing down into the pump. If the water trap fills the water block filter will stop the flow to the analyzer and FLO ERR will display. The water trap should be emptied immediately if this happens. The water block filter may need to be dried out or replaced before testing can resume.

• Combustion Display 4
• Displays CO air free (-CF-)
CO air free takes into account excess air (make up air) and factors this out of the displayed reading. Some systems inject extra air to ensure complete combustion. This can dilute the CO sample resulting in a low CO reading when the standard CO display is being read.
This display should be used if the manufacturer specifications are stated as CO air free. If it is used on a system that is not specified in CO air free the displayed reading may appear abnormally high as compared to the manufacturer specification.
The formula for CO air free is: COairfree = (20.9/20.9 - O2 meas.) x CO meas.

Appendix A: General Maintenance
All combustion analyzers use consumable items such filters and probes. These items are user serviceable and can be taken care of by the operator.
The consumable items that will require operator attention are the water trap / filter assembly, flue probe, pump protection filter, and ambient temperature probe.
The recommended maintenance schedule for your analyzer is as follows:
Maintenance Performed
Water trap Check
Filter Check
Frequency
Once per week (Once per day for analyzers that see heavy use or are used in oil fired applications)
Pump Operation Check Once per month (More often for analyzers
Flue Probe Integrity Check that see heavy use or are used in oil fired
Thermocouple Probe Check applications)
Water Trap Check
Visually check the water trap for:
1. Cracks in the bowl.
2. Broken ears on the bowl where the lid locks on.
3. Broken ears on the lid.
4. Worn out o-ring on the lid.
5. Loose connection to the flue probe tubing.
Filter Check
Signs of dirty or water saturated filters are a slow pump, flow error displayed when the flue probe is connected, and measurements that take longer than normal.
TPI analyzers use three filters to protect the pump and sensors. The first filter to check is the A763 mini pump protection filter. (see picture below)
Strain Relief Spring Inspection Window
A763 Pump Protection Filter
Look in the inspection window to check the filter. When the filter material becomes dark, pull the black nose cone out of the tubing and replace the ball filter inside.
30
Appendix A: General Maintenance (continued)
Filter Check Continued
The other two filters are located in the water trap. The main filter is the A794F particle filter. This filter stops debris and dust from traveling down to the analyzer. The secondary filter is the A794W water block filter. This filter stops flow in the event the water trap fills with condensate. Refer to the picture below.

Water trap lid. O-ring is located in the lid recess
Open the water trap and look at the A794F particle filter. The filter will typically get dirty from the inside first. If the filter is dark on the inside a replacement filter should be installed.
If the A794F is clean but saturated with water a replacement should be installed to ensure proper flow. The saturated filter can be left to dry and reused later.
Pump Operation Check
1. Turn the analyzer on as outlined on page 8. Do not connect anything to the inlet. Wait until the analyzer has completed the initial purge and sensor check and is operating normally prior to proceeding to step 2.
2. Cover the analyzer inlet with your finger. The analyzer should display “FLO
ERR” and a rapid beeping should be heard.
If the analyzer does not beep and display “FLO ERR” this may be an indication the flow sensor requires calibration, the pump is faulty, or there is an internal leak. The analyzer should be returned for factory service.

Flue Probe Integrity Check
NOTE: Perform this check after performing the Pump Operation Check outlined on the previous page.
1. Turn the analyzer on as outlined on page 8. Do not connect anything to the inlet. Wait until the analyzer has completed the initial purge and sensor check and is operating normally prior to proceeding to step 2.
2. Connect the A763 mini pump protection filter and flue probe assembly to the inlet of the analyzer and the yellow thermocouple connector to input T1.
3. Repeatedly press the Scroll/Enter key until temperature is displayed. If the displayed temperature is approximately the ambient temperature the thermocouple is operating properly and you may proceed to the next step to continue the test. If the displayed temperature is “OL” the thermocouple is open and the probe is in need of factory service.
4. Cover the end of the flue probe with a small piece of tube and pinch the end close. After a short period of time the analyzer should display “FLO ERR” and a rapid beeping should be heard. If this happens the flue probe his operating properly and the integrity test is complete. If the analyzer does not display “FLO
ERR” this is an indication of a possible leak somewhere in the flue probe and you may proceed to the next step for further tests.
5. Pinch the hose below the handle of the flue probe. If the analyzer displays
“FLO ERR” there is a leak in the handle assembly and the probe needs to be factory serviced. If the analyzer does not display “FLO ERR” proceed to the next step for further tests.
6. Pinch the hose between the analyzer and the water trap. If “FLO ERR” still does not display there may be an internal leak, pump problem, or other issue and the analyzer needs to be factory serviced. If “FLO ERR” is displayed there is a leak in the water trap assembly and the water trap assembly should be checked as outlined on page 39 & 40.
Appendix B:
A773 SULFUR FILTER INSTALLATION & MAINTENANCE
When performing combustion tests on oil fired equipment it is important to use the optional A773 sulfur filter. Failure to do so can result in incorrect and readings. This filter also protects the sensors from the affects of sulfur. The
A773 does not have to be removed when working with other types of fuels.
PROCEDURE

Appendix G: Technical Notes
Note 1: When performing a pressure or draft test during a combustion test, the pump can be turned on to provide a continuous sample to the sensors. This enables pressure adjustments to be made and the affect to the combustion process can be seen by returning to combustion analyzer mode. Use the FUNC
Key to activate manometer mode. Press and hold the Up Arrow Key until the pump reactivates. Perform a pressure test and then use the FUNC key to activate combustion analyzer mode. Repeat this process until pressure adjustments are complete.
Note 2: Several factors affect combustion efficiency. Dirty or clogged air filters reduce the amount of air available for combustion therefore reducing efficiency.
Obstructions in the flue block exhaust gases and alter the air mixture in the combustion chamber which reduces efficiency. Air leaks in the combustion chamber also alter the mixture causing decreased efficiency.
Note 3: The primary way to affect change in combustion efficiency when working with modern gas fired equipment is through gas manifold pressure adjustment. Confirm manifold pressures are within maufacturers specifications prior to performing a combustion test. Once manifold pressures are within limits a combustion test can be performed to provide information regarding any adjustments that may be needed.
Appendix H: Testing for Carbon Monoxide in Ambient Air
The 712 can be used to test for carbon monoxide in ambient air. For example tests can be performed in work spaces and living areas like offices and houses to ensure safety.
1. Following the steps outlined on page 8, turn the analyzer on in a clean air environment away from the area to be tested,
2. After the purge cycle is complete combustion display 1 will be seen. This is the default start up display and is the display to use when performing this test.
Please see below.
The top display shows the carbon monoxide level.
For this test, ignore the middle and bottom displays.
3. Connect the Mini Pump Protection filter to the analyzer. See picture below.
40
4. Begin testing for carbon monoxide. Move from space to space to detect any
CO that may be present. The CO reading will be seen in the top part of the display.
5. If necessary, the flue probe can be attached to test in ducts and plenums.
6. Refer to the chart on page 42 for a list of exposure times and levels of carbon monoxide in ambient test applications
7. When testing is complete, turn the analyzer off as outlined on page 8.

Appendix I: Carbon Monoxide in Ambient Air Chart
This chart contains maximum exposure levels and times for carbon monoxide.
This is a general guidline only. It is recommended you check with your local government for guidelines in your area.
Appendix J: CARBON MONOXIDE FACTS
Carbon Monoxide (CO) is invisible, odorless, and tasteless. It is the byproduct of combustion and levels are elevated when there is incomplete combustion.
Sources of CO include:
Unvented kerosene and gas space heaters
Leaking chimneys & furnaces
Gas water heaters
Back drafting from furnaces
Wood stoves& fireplaces
Gas Stoves
Automobile exhaust
Tobacco smoke
Carbon Monoxide is picked up quickly in the body by red blood cells. At high levels of CO the body replaces oxygen with carbon monoxide.
The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. High levels of CO inhalation can cause loss of consciousness and death. Unless suspected, CO poisoning can be difficult to diagnose because the symptoms mimic other illnesses.
People who are sleeping or intoxicated can die from CO poisoning before ever experiencing symptoms.
Please see the next page for a list of exposure times and symptoms.
