Operating Instructions
The TPI 712 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.
The TPI 712 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.
Keep the battery of the 712 charged so power is constantly being supplied to the sensors.
The following guidelines will help prevent damage to the 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.
- Never over saturate your sensors by performing tests on equipment with gas levels beyond the capability of you analyzer.
- Always keep the A762 water trap / filter assembly clean and replace the filter as necessary. Replacement filter part number is A762F.
Using TPI analyzers to determine combustion efficiency at the time of equipment set up minimizes call backs and can be used to verify to the home owner the value of service work by showing the increase in equipment efficiency after work is performed. Efficiency calculation can also be used to generate business by demonstrating the need to improve the efficiency of equipment or to show the benefit of purchasing new equipment with higher efficiency
The TPI 712 Flue Gas Analyzer has the following options available:
- PC Software for analysis of Data Logging results
- Infrared PC link for non compatible PCs

Tech Tips
Several factors affect combustion efficiency.
Dirty or clogged air filters reduce the amount of air available for combustion therefore reducing efficiency. Obstructions in the flue block exhaust gases and alter the air mixture in the combustion chamber which reduces efficiency. Air leaks in the combustion chamber also alter the mixture causing decreased efficiency.
The primary way to affect change in combustion efficiency when working with modern gas fired equipment is through gas manifold pressure adjustment.
Confirm manifold pressures are within manufacturers specifications prior to performing a combustion test. Once manifold pressures are within limits a combustion test can be performed to provide information regarding any adjustments that may be needed.
10,000ppm is equal to 1%.
The formula to convert percent to ppm is: ppm = %gas X 10,000. The formula to convert ppm to percent is: % = ppm / 10,000.
The 709, 712, and 714 incorporate a differential manometer.
Pressure applied to the (-) port is subtracted from the pressure applied to the (+) port. Examples of pressures being measured:
- (+) port = 10" H2O, (-) port = Not Connected, Displayed reading =10" H2O
- (+) port = 10" H2O, (-) port = 5"H2O, Displayed reading = 5"H2O
- (+) port = Not Connected, (-) port = 10" H2O, Displayed reading = -10" H2O
