Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.
This error is not relaated to your new install. Try this, turn the power off to the boiler wait a couple minutes then turn it back on again. Tell me what happens. Does the boiler fire up then go out? Do you have the manual?
It's likely either the igniter or the flame sensor. If the burner fires up then goes out you need to clean or replace the flame sensor. If it doesn't fire up then do you have a spark? The electrode gap shuld be checked and reset according to the specs in the manual (1/4" gap). cleaning the electrode is also a good idea. If you have a spark but no ignition then they should check for 24 volts at the gas valve while the igniter is sparking.
Do you have more questions?
