1. Introduction
2. General Overview
The TPI 714 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.
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 battery of your 714 charged 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.

4.1 Turning On
Always: - Before turning on please ensure that the Mini Pump Protection Filter
assembly and the Temperature Sampling Probe complete with In-Line Filter or the Tubing & In-Line Filter for Leak Detection are not connected to the Gas Sample Port (see 2.2 or 2.4)
Press and hold down the Power Key and the TPI 714 will start its 30 second countdown 'PURGE' will be displayed: - The instrument MUST be turned on in a clean air environment as the 30 second purge will set the Carbon Monoxide level to Zero and the Oxygen to 20.9%. The 714 may re-start the coutdown several
times before normal operation. This means the sensors are still initializing and is normal.
Ensure that the filters are clean and dry as dirty or wet filters will result in a loss of flow rate and 'Lo Flo' will be displayed to inform you that filters should be changed
During the last 20 seconds of the 30 second purge time the user can scroll through the following Fuels: - Natural Gas, LPG, Light Oil, Heavy Oil, OPT1 : Bituminous Coal, OPT 2 : Anthracite Coal, OPT 3: Coke, OPT 4: Butane, OPT 5: Wood (Dry), OPT 6: Bagasse by pressing the Up Arrow Key to select the Fuel they are working with. When desired fuel is displayed release the key, displayed fuel is now selected.
After the 30 second countdown the instrument is ready to take Flue, Temperature, Pressure or Leak Detection readings and Combustion Display 1 will be the first display.
The 714 will auto power off if no keys have been pressed for 10 minutes and the CO level is below 15ppm.
The Scroll/Enter Key allows you to scroll through the combustion displays as out­lined in section 5.3. The Func Key is used to select the 714 function mode and allows you to set it to be a combustion analyzer, manometer, thermometer, or combustible leak detector. In addition, the Func Key is used to access the date and time display. See section 6 for more information on the Func Key.
4.2 Turning Off
NOTE: When selecting oil as fuel be sure to use the optional
oil filter (A773) or readings could become erratic. See Appendix E for installation instructions.
4.2 Turning Off
Always: - Before turning off return the instrument to a clean air environment and
allow the Carbon Monoxide level to return to below 15ppm and the Oxygen level to return to 20.9% (± 0.3%) Press the Power Key to turn the instrument off:­NOTE Should you attempt to turn the instrument Off and the CO reading is above 15ppm then the instrument will remain On and a short Beep will be heard. The Instrument can only be switched off if the CO is below 15ppm
The instrument has an auto shut off after 10 minutes should no keys have been pressed for this period and as mentioned above that the CO is below 15ppm. Should the CO be above 15ppm then the 10 minute auto shut off countdown will not begin till the CO has gone below 15ppm
4.3 Charging
Plug the Charger supplied into the charger socket on the instrument (see 3.4). If
the instrument is turned on then a charging symbol will be displayed. Should the instrument then be turned off, turn off automatically or be turned off when the charger is plugged in then the charging symbol will not be displayed BUT the instrument will still be charging.
The instrument should be charged overnight for a period of 10 to 12 hours and
will give over 6 hours Operating Time. If a beeping noise is heard during charging disconnect the charger. This is an indication of something wrong in the charging circuit. Please contact TPI technical assistance at 800-368-5719.
Alternatively, the instrument can be used when plugged into the charger.
4.4 Activating the Backlight
The display backlight can be activated at any time by pressing and holding down

COMBUSTION ANALYSIS (Continued)
5. COMBUSTION ANALYSIS
5.1 Overview
Testing for carbon monoxide, oxygen, and stack temperature 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 included figures show locations for performing tests on commonly encoun­tered equipment. Remember to consult with the manufacturer of the device under test for specific test information.
NOTE: When selecting oil as fuel be sure to use the optional
oil filter (A773) or readings could become erratic. See Appendix E for installation instructions.

5.2 Procedure
1. Turn the 714 on as outlined in section 4.1. At any time you can activate the Backlight by holding down the Func/Backlight Key for 2 seconds. The back­light will automatically shut off after 20 seconds to preserve battery life.
2. Ensure you have connected the Mini Pump Protection Filter assembly and Temperature Sampling Probe complete with In-Line Filter to the Gas Sample Port (see 3.2 or 3.4) and the 'K' Type Thermocouple Plug into Thermocouple (T1) Socket (see 3.4). The GK11M ambient air temperature probe must be connected to the (T2) socket. (refer to figure below for correct hookup)
WARNING: - Ensure that the In-Line Filter hangs in a vertical position when readings are being taken, particularly if water is visible. Failure to comply may result in damage to the instrument.
WARNING: - There is ONLY one correct way to connect the 'K' type thermo­couple plug into the socket (see 2.4). Forcing the plug into the socket the wrong way round may result in damage to the instrument.
3. Insert the flue probe into the test location of the device under test. The probe tip should be in the middle of the flue pipe or exhaust stream. Refer to figures 1 through 3 for typical test locations.
