1.4 Sequence of Operation

Operational State

User Interface Display

Explanation

If flame detected before Gas Valve opens  

during ignition boiler will lockout.
Please refer to troubleshooting guide.

Gas Valve energized to deliver air/fuel to 

burner.

If flame undetected after 3 seconds boiler 

will de-energize Gas Valve and enter post 

purge mode for 30 seconds.
Ignition attempted 5 times before 

lockout.

Boiler will run provided all operational 

and safety devices are within limits
Refer to for more information.

Control module adjusts firing rate 

according to heating demand.  When 

Boiler detects demand met, will enter 

post purge mode then standby mode.

  

If simultaneous demand for Central Heat 

and DHW, boiler will enter DHW Priority 

Mode.
Priority mode limits amount of time 

boiler can run in DHW mode to meet CH 

demand.
Max DHW Priority Time setting 

determines maximum time allowed for 

DHW heating mode.
Please refer to section Appendix A section 

1.5 for more information.
