Operation
4. You can now begin burner-service procedures. The analyzer readings
will change quickly to show changes in burner performance.
CAUTION: Position the Water Trap with its gas-flow arrow
pointing upward. Do not let water condensate go above the tip
of the riser tube. The sensors could be damaged if water would
enter the analyzer. Empty the Water Trap after every combus-
tion test (refer to Section 4.9)
5. Pressing the RUN/HOLD button freezes all readings, stops the pump and
displays the Combustion-Test HOLD screen. Press the ENT button to view
all test values at the moment the RUN/HOLD button was pressed. Press-
ing RUN/HOLD again restarts the pump and resumes testing.
