My Dunkirk Boiler is not igniting. The pilot is on and when the thermostat calls for heat the furnace circulates, dampers opens, fan starts but the burners do not ignite. Help!

If the PV stands for power vent check the pressure control.0

The pvwb I looked up has a spark ignition. Try cleaning the flame sensor and pilot0

I would make sure the flue damper is opening all the way. If it is you should check for 24 at the B1 and B2 on the aquastat.0
