To Flush or Not to Flush Oil Fired Steam Boiler

2 weeks ago had a new install of oil fired steam boiler (Williamson OSB-3 2 Series) What is the homeowner's responsibility to do to keep system functioning correctly and avoid problems with heat, hot water and warranty? Kind of afraid to touch anything. The manual does not clearly state if flushing is necessary or if so, how often or how to do.
It has VXT auto water feeder and , tankless coil and Probe type LWCO. Previous boiler was only 13 yrs old (New Yorker) and had manual water valve. Tank became corroded and leaked even though I had it serviced "tuned-up" each year.
Not sure what went wrong.

    What was the overall cause of failure on the previous boiler?
    Hopefully the boiler was sized and installed correctly.

    Very much agree with @EzzyT 's questions! But in a slightly more direct answer to yours, the three most important things you, as the homeowner, can and should do are to make sure that if there is a float type low water cutout that it is flushed occasionally, to make sure the float is free, and to keep track of the water usage -- and to have the boiler cleaned and serviced by a competent technician, with the necessary tools and instruments and the knowledge to use them, once a year.

    13 years is actually not an unusually short lifetime, but tracking the water usage will indicate whether or not you have some leaks -- which have to be addressed, as too much fresh water can cause a premature failure.
