the flue‑gas stream, and then allowing the
pump to run until the O

Turning OFF the Analyzer
11. Turn OFF the analyzer by pressing the I/O
button. There is a 5‑second delay before the
analyzer actually turns OFF, during which
time the unit can be turned back ON by
pressing the ENTER button.
A Fyrite Tech 60 will not turn OFF if a high
level of CO is still being detected. The pump
will remain running and the message “PurG
CO” is displayed until the detected CO level
drops below 50 ppm. This purge process can be
bypassed by again pressing the I/O button.
