Checking/replacing the particle filter
Checking the particle filter:
Check the particle filter of the modular flue gas probe periodically
for contamination: check visually by looking through the window
of the filter chamber.
> If there is visible contamination or inadequate pump flow,
replace the filter.
Replacing the particle filter:
The filter chamber may contain condensate. This is not a
malfunction and will not cause wrong readings.
