Using the modular flue gas probe

Checking the thermocouple
The thermocouple of the flue gas probe must not lie against the
probe cage.
> Check before use. Bend the thermocouple back if necessary.
Aligning the flue gas probe
The flue gas must be able to flow freely past the thermocouple.
> Align the probe by turning it as required.
When using the testofix® probe mount, the measuring
instrument is exposed to heat radiating from the flue gas duct
during the measurement. In order to prevent consequently
affecting the combustion air temperature a AT probe with
cable must be used for the measurement!
