boiler water

I will drain and refill on start up after the boiler cycles a few times to clear the existing rust, any flux that may have been left behind in the system and just to see the condition of the water on a new installation. I might repete this again in about 5 to 10 years depending on what I see during a PM check.

If this is a steam heater, I'd drain it only enough to ensure that the low-water cutoff switch is working properly and has not been obstructed by sediment (if applicable). My neighbors steamer dry-fired itself to death because its switch did not trip...
