=== Low Air Pressure === | === Low Air Pressure === | ||
The <b>Low Air Pressure</b> switch closes when the positive air pressure differential formed in the combustion chamber meets a minimum threshold. Assuming the blower is operating, insufficient air pressure may be the result of: | |||
* Excessive air leakage. Tighten enclosure bolts and an adequate seal is present. Sometimes, pushing on the boiler's combustion chamber enclosure panel may be enough to force marginal pressure over the threshold. | |||
* Improper airflow adjustments. Consult a qualified technician; blower airflow may need to be adjusted. | |||
* A failed air pressure switch, or an electrical issue. Repair may be necessary. | |||
This fault may be identified by the [[Pool Systems Automation#Boiler Status|boiler status]] indicated the LCD on the automation system PLC. | |||
