3.0Boiler Operation

3.1Boiler Operation

1.Switched Live On: When switched live is supplied to the boiler and the flow temperature is less than the set point the sequence below commences.

2.Flow Switch: After 10 seconds if the flow switch has made then fan pre-purge occurs. After 10 seconds if the flow switch has not made then anti-cycle occurs.

3.Fan Pre-Purge: The flow switch is made and the fan is on while the spark generator and gas valve are off. After 5 seconds ignition occurs.

4.Ignition: The flow switch is made, fan, spark generator and gas valve are on. If a flame is detected then burner on occurs. If a flame is not detected within

5seconds and less than 5 ignition attempts have been made then fan purge occurs. If a flame is not detected within 5 seconds and 5 ignition attempts have been made then ignition lockout occurs.

5.Burner On: The flow switch is made, fan and gas valve are on while the spark generator is off. Flow temperature is controlled by varying the fan speed (and thereby the gas rate) to achieve optimum operation. If the flow temperature is greater than the set point or the TRVs all shut down then fan post purge occurs.

6.Fan Post Purge: The fan is on while the spark generator and gas valve are off. After 5 seconds if the TRVs are shut down then anti-cycle occurs.

7.Anti-cycle: The fan, spark generator and gas valve are off.

8.Ignition Lockout: The fan, spark generator and gas valve are off. The boiler can only be reset by manually using the reset button.

9.Condensate Pump: Condensate accumulates in a reservoir within the pump assembly. The pump may run at any time, independent of boiler operation, to discharge the condensate to drain.
