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 717 will start its 30 second countdown 'Purging...' will be displayed. -
Page 11: Turning The Analyzer Off
Temperature, and Pressure readings and the default combustion display will be displayed. The 717 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 717 on in fresh air as outlined on page 8. After the initial purge cycle the 717 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.

User / Factory Replaceable A760 **Sensor replacement requires calibration gas. Sensors for the 717 can be replaced in the field. Please see appendix # for the replacement procedure. WARRANTY Your TPI 717 Flue Gas Analyzer is guaranteed free from defects in materials and workmanship for 3 Years from the date of purchase. -
Page 34: 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 35 Appendix A: General Maintenance (continued) Filter Check Continued The other two filters are located in the water trap (p/n A796). The main filter is the A762F 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.
- Page 36 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 37: 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 38 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.
