Weil-McLain boilers occasionally shut themselves down with an error E04 code after power outages. You can read more about the problem from this Weil-Mclain Technical Services Bulletin. The fix is quite simple, all you need to do is hit the reset button and your boiler should fire back up and work properly again.
If you own a Weil-McLain Ultra boilder you really should check it after each power outage. This will certainly save you from a very cold morning or shower the next day.

Wow, what a nice looking pex manifold I see mounted on the wall! Usually I have seen those look like a rats nest instead of a neat easy to look at manifold like that one!
I don't have a boiler, but thought I would comment on the manifold anyway.
