What are the symptoms of over-firing? The boiler is an SGO-4 with the 1.10 gpm nozzle that came with the package. Would the next step down be a 1.0?

    Vaporstat Setting

    I just installed a Vaporstat on my new one-pipe steam system to lower the pressure to reduce vent whistling.

    I had it set with a 4-oz cut-in and 10-oz cut-out. At this setting, the system heated all the radiators, but there was some whistling at the last moments of the steam cycle.

    I dropped the cut-out to 8-oz and there was no whistling, but the system cuts-out on pressure and then cuts back in three times in just a few minutes before the thermostat is satisfied.

    Should I be raising the cut-out or lowering the cut-in pressure. The radiators are all hot before the steam cuts off, it's just that the thermostat is not satisfied.

    Thanks,

    Steve

    The boiler

    may be slightly oversized for the system. Try having a pro down-fire it a bit.
