WARNING!
Turning the pump off while the probe is in the flue will leave toxic
gases inside the analyzer. Once data has been read, it is advisable to
purge the unit with fresh air as soon as possible. To do this, with the
probe removed from the flue, turn ON the pump. Always allow the
readingstoreturntozero(00forCO)priortoshuttingtheunitoff.
WARNING!
The probe will be hot from flue gases. Remove the probe from the flue
