    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.
  • Page 4 Always keep the A794 water trap / filter assembly clean and replace the filter as necessary. Replacement filter part number is A794F. This manual will guide you through the functions of the TPI 709 which will give you many years of reliable service.

    The instrument MUST be turned on in a clean air environment as the initial purge will set the Carbon Monoxide level to Zero and the Oxygen to 20.9%. Press and hold down the Power Key and the TPI 709 will start its 30 second countdown 'PURGE' will be displayed.

  • Page 11: Turning The Analyzer Off

    Temperature, Pressure or Leak Detection readings and the default combus- tion display will be displayed. The 709 will auto power off if no keys have been pressed for 10 minutes and the CO level is below 15ppm. Auto off can be disabled (see Appendix D). The auto power off feature is always enabled upon power up.

  • Page 12: Combustion Analysis Overview

    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.

  • Page 13: Combustion Analyzer Mode

    Please refer to Appendix A for general maintenance schedule and function tests. 1. Turn the 709 on in fresh air as outlined on page 8. After the initial purge cycle the 709 will default to combustion analyzer mode and combustion dis- play 1 will be seen.
  • Page 14 IMPORTANT: Prior to taking a sample, the device under test should be on and at operating temperature. 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.

    5. Allow the readings to stabilize. Multiple combustion analysis displays are available to provide the various test results. Use the Scroll/Enter Key to move through the various combustion displays. • Combustion Display 1 (Default Start Up Display) • Displays Carbon Monoxide (CO) reading in parts per million (ppm) •...
  • Page 20 • 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.

    Typical Test Results Actual test results vary depending on the equipment under test. TPI recommends you check with the manufacturer of the equipment being tested to determine specific acceptable results. Power Burners (Gas Fired) Oxygen 3% to 6% Carbon Monoxide Less than 100ppm (air free)

    The 709 incorporates a differential manometer. This means when a single hose is connected to the (+) port and pressure is applied, the 709 will read positive pressure. If a single hose is connected to the (-) port and pressure is applied, the 709 will read a negative pressure.

    **Sensor replacement requires calibration gas. WARRANTY Your TPI 709 Flue Gas Analyzer is guaranteed free from defects in materials and workmanship for 3 Years from the date of purchase. This guarantee does not affect your statuary rights. For additional information please refer to the included warranty card or contact TPI at 800-368-5719.

  • Page 32: Appendix A General Maintenance & Function Tests

    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)
  • Page 33 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 analyz- er. The secondary filter is the A794W water block filter. This filter stops flow in the event the water trap fills with condensate.
  • Page 34 Appendix A: General Maintenance (continued) 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.

  • Page 35: Appendix B A773 Sulfur Filter Installation & Maintenance

    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.
  • Page 36 Appendix B: A773 SULFUR FILTER INSTALLATION & MAINTENANCE 4. Beginning on the “Flue Probe” side of the A773 sulfur filter, pull the yellow thermocouple cord out of the channel of the flue probe tube. Pull out approx- imately the length of the water trap that was removed. 5.
