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.
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 sen-
sors in your analyzer will need to be replaced periodically and calibra-
tion is recommended once every year. The 708 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 war-
ranted for two years. This warranty does not cover sensors damaged
through misuse of the analyzer.
You should keep the batteries of your 708 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 fil-
ter / water trap assembly prior to performing tests.
Always use the optional oil filter (p/n A773) when performing tests on
oil burning equipment.
