today I did maintenance on my Lochinvar Noble 199. I flushed the fire tubes and flushed the domestic heat exchanger then set combustion.

One thing I’ve never done is flush the water on the boiler side. Does this also need to be done?

    Not if it's got the proper chemistry and there is no oxygen intrusion
