MEASURING FLUE GASES
After the countdown is finished and the analyzer is correctly set up, put its’ flue probe into the
appliance’s sampling point. The ideal sampling point is at least two flue diameters
downstream of any bend.
Put the probe tip in the flue center. With balanced flues, make sure the probe is positioned far
enough into the flue so no air can ‘back flush’ into the probe.
Use the probe’s depth stop cone to fix it in flue diameters from
1
/
4
to
4
/
5
inch, 6 to 21 mm. Its
maximum operating temperature is 1112
°F / 600°C.
Make sure you do not exceed the analyzer’s operating specifications. In particular:
• Do not exceed the flue probe’s maximum temperature
• Do not exceed the analyzer’s internal temperature operating range
• Do not put the analyzer on a hot surface
• Do not exceed the water trap’s levels
• Do not let the analyzer’s particle filter become dirty and blocked
View the displayed data to ensure that stable operating conditions have been achieved and the
readings are within the expected range.
