Typical Test Results

Actual test results vary depending on the equipment under
test. TPI recommends you check with the manufacturer of the
equipment being tested to determine specific acceptable
results.

Oxygen

3% to 6%

Carbon Monoxide Less than 100ppm (air free)

Stack Temperature

300

°F

to 500

°F

Oxygen

4% to 7%

Carbon Monoxide Less than 100ppm (air free)

Stack Temperature

325

°F

to 625

°F

Power Burners (Gas Fired)

Power Burners (Oil Fired)

Oxygen

7% to 9%

Carbon Monoxide Less than 100ppm (air free)

Stack Temperature

325

°F

to 500

°F

Gas Fired Burners (Atmospheric / Fan Assist)

• 

Combustion Display 4

• Displays CO air free (-CF-)

CO air free takes into account excess air (make up air) and
factors this out of the displayed reading. Some systems
inject extra air to ensure complete combustion. This can
dilute the CO sample resulting in a low CO reading when the
standard CO display is being read. 

This display should be used if the manufacturer specifications are stated
as CO air free. If it is used on a system that is not specified in CO air free
the displayed reading may appear abnormally high as compared to the
manufacturer specification. 

The formula for CO air free is: COairfree = (20.9/20.9 - O2 meas.) x CO meas.

Pressing the Scroll Enter key changes the display:

• 

Combustion Display 5

• Displays Temperature reading of Channel 1 (T1) 
• Displays Temperature reading of Channel 2 (T2) 
• Displays the Differential Temperature (Diff.) between ch1

and ch2 

• 'oPEn' will be displayed if no 'K' type probe is connected to

the thermocouple socket

• Press the Up Arrow Key to switch between ºC and ºF

Pressing the Scroll Enter key again will make the display return to combus-
tion display 1 (Default display)

6. During a combustion test you can save, print, and recall datar. See pages
22 through 25. Allow readings to stabilize before saving or printing the data.
Refer to page 19 for typical test results.

7. After the test is complete, remove the flue probe from the test location and
allow the analyzer to purge in a fresh air environment with the probe
attached. Make sure the analyzer purges to below 15ppm. Never remove the
battery to turn the analyzer off before the purge is complete. Refer to page 9
for complete instructions.
