OPERATION EDR-SOLA-IOM-2022-0216 SECTION 3
11. Once nal eld combustion is completed at low and high re, the ignition
enrichment setting requires verication. Input the light o RPM into the
SOLA “manual ring rate” screen (Figure 33).
12. Connect an inches of water column measuring device (e.g., manometer)
to the enrichment gas valve test port (Figure 27). Insert a calibrated
combustion analyzer probe into the ue gas outlet port.
13. Open the front access door and locate the Enrichment test button located
at the top of the electrical box. Pushing the Enrichment test button
(Figure 29) activates a “1-shot relay,” allowing 30 seconds to measure the
Enrichment gas valve outlet pressure and stable O%. Use the factory test
re report to reference the Enrichment gas valve outlet pressure and O%.
(site conditions will ultimately determine specic settings).
For metal woven mesh burners only: Verify O percentage is within the
range listed in Table 9. Consult the factory for boilers operating with
ceramic mesh burners.
NOTE: Button should only be pushed ONCE during this exercise.
NOTE: The eld O% at low re impacts
the Enrichment O%. Always set eld
combustion at low and high re prior to
completing the above steps!
14. The enrichment gas regulator (Figure
28) may be used to increase or
decrease the valve outlet pressure as
required.
15. Once combustion is veried with a
combustion analyzer place the control
back into automatic mode and check
all boiler safeties.
