Per the Weil- McLain EG55 Boiler manual the recommended voltage and breaker size is 120v at 15amps. If you apply Ohms Law, Volts * Amps = Watts or 120*15= 1,800 Watts. If you look at the boiler data plate it may list LRA (Line Running Amps) which may be higher, usually at start up. Also consider what the heater has in addition such as motors that also draw additional power at startup. You should also look at the breaker size on the generator and make sure it is not less than 15amps and I doubt you would be able to run much more with the heater operating.
