Description

AUTHORIZED DISTRIBUTOR
Combustion Efficiency Analyzer w/ Differential Manometer.
The carbon monoxide sensor used in TPI combustion efficiency analyzers feature an on-board filter capable of filtering NO (nitric oxide), NO2 (nitrogen dioxide) and NOX (combination of NO and NO2) to prevent cross sensitivity errors.
Use TPI analyzers to test flue gases in gas and oil fired equipment including high efficiency furnaces and condensing boilers. Measure CO, O2, and stack temperature.
Determine combustion efficiency, CO2, and CO air free. Built-in differential manometer, combustible gas detection, PC communication, data logging, and can measure NO / NOX.

Frequently Asked Questions
When should I use the optional A773 oil filter?
If your analyzer is used in an oil fuel application the A773 filter should be used. This filter does not have to be removed for other fuel types.
Should I set my analyzer to net or gross efficiency?
Gross efficiency is the correct choice for applications in the United States.
Can I use any of the TPI analyzers to test for the presence of combustible gas in the flue?
Yes, the 712 has the ability to test for combustible gases in the flue.
Can I log and send test data to a computer?
Yes, the 712 and 714 have the ability to communicate to a computer by using the optional A767 infrared adapter.
Can I test for CO in ambient air?
Yes, the 708, 709, 712, and 714 can all test for carbon monoxide in ambient air.
Do any of the TPI analyzers have a built in manometer?
Yes, the 709, 712, and 714 have built in differential manometers.
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
Sensor Calibration
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.
