the measurement cells. This is also the reason why it is important to periodically drain the trap, anyhow at the
end of each test (see chapter 'MAINTENANCE').
A replaceable low-porosity line filter is placed after the condensate trap aimed at keeping the solid particles
suspended in the gases. It is recommended to replace the filter whenever visibly dirty (see chapter
'MAINTENANCE').
4.5 Connecting the combustion air temperature probe
Should you need to measure the actual
combustion air temperature
and the analyser is not in the place where
the combustion air is to be taken (important for a correct calculation of the burner efficiency), you shall use the
remote probe.
The remote probe is made up of a Pt100 thermal resistance equipped with cable (available 3 meters long) and
connector for its connection to the analyser.
4.6 Connecting the TcK probe
Using the same input as for the K thermocouple (the same used for fumes temperature), it is possible to measure
the water delivery and return temperature by connecting some
special probes
. If temperature is taken on the
pipe, it is suggested to use arc probes with a suitable diameter.

KEEP THE CONDENSATE TRAP IN THE VERTICAL POSITION DURING THE ANALYSIS; A
WRONG POSITIONING MAY CAUSE CONDENSATE SEEPAGES IN THE INSTRUMENT AND
DAMAGE SENSORS.
AFTER EACH ANALYSIS, CHECK FOR ANY PRESENCE OF WATER IN THE CONDENSATE
COLLECTION BOWL AND ELIMINATE IT, IF ANY. PUT THE PROBE BACK IN THE CASE ONLY AFTER
YOU HAVE ELIMINATED CONDENSATE FROM THE TUBE AND THE EXPANSION TANK (SEE CHAPTER
'MAINTENANCE').
REPLACE THE FINE DUST FILTER IF IT IS VISIBLY DIRTY OR WET (SEE CHAPTER 'MAINTENANCE').
DO NOT PERFORM ANY MEASUREMENT WHEN THE FILTER IS REMOVED OR DIRTY IN ORDER TO
AVOID ANY RISK OF IRREVERSIBLE DAMAGES ON SENSORS.
