Appendix A: General Maintenance (continued)
Flue Probe Integrity Check
NOTE: Perform this check
AFTER
performing the Pump Operation Check outlined on
the previous page.
1. Turn the analyser on as outlined on page 9. Wait until the analyser has completed
the initial purge and sensor check and is operating normally prior to proceeding to
step 2.
2. Connect the flue probe assembly to the in-line pump protection filter which should
be connected to the analyser and the yellow thermocouple connector to input T1.
3. Navigate to “Flue Gas” screen and start the pump running as outlined in pages 11
to 14. Press the down arrow key so that temperature is displayed. If the displayed
temperature is approximately the ambient temperature the thermocouple is operating
properly and you may proceed to the next step to continue the test. If the displayed
temperature is “OL” the thermocouple is open and the probe may be in need of
factory service. Please call the Technical Helpline on 01293 530196 opt. 1
4. Cover the end of the flue probe with a small piece of tube and pinch the end
closed. After a short period of time the analyser should display “Flow Error” and a
rapid beeping should be heard. If this happens the flue probe his operating properly
and the integrity test is complete. If the analyser does not display “Flow Error” this is
an indication of a possible leak somewhere in the flue probe and you may proceed to
the next step for further tests.
5. Pinch the hose below the handle of the flue probe. If the analyzer displays “Flow
Error” there is a leak in the handle assembly and the probe may need to be factory
serviced. If the analyser does not display “Flow Error” proceed to the next step for
further tests.
6. Pinch the hose between the analyzer and the water trap. If “Flow Error” still does
not display there may be an internal leak, pump problem, or other issue and the
analyser may need to be factory serviced. If “Flow Error” is displayed there is a leak
in the water trap assembly and the water trap assembly should be checked as
outlined on page 34.
