I have a new Vaillant F75-60 package boiler with the
Becket AFII. From the factory it is configured with a
1.10x45B nozzle @170psi. I bought this boiler with an increase in heat load in mind, until that expansion takes place can I down fire the burner? The steel boiler that was replaced was burning 1.00gph with the current load.
