1. Introduction

Thank you for purchasing TPI brand products. The TPI 708 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.

2. General Overview

The TPI 708 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 708 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. Turning On & Off

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 708 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%.

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 708 will auto power off if no keys have been pressed for 10 minutes and the

CO level is below 15ppm. This feature can be disabled see Appendix F.

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 708 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

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 Activating the Backlight

The display backlight can be activated at any time by pressing and holding down the Func Key for approximately 2 seconds. The backlight will automatically shut off after approximately 20 seconds to preserve battery life.

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. 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.



COMBUSTION ANALYSIS (Continued)

5.2 Procedure

1. Turn the 708 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.
