Energy kinetics system 2000 input rates

I noticed on my new boiler that it lists four input rates from .68 to 1.00 gph of oil for the EK1,  is this input rate set by the installer or is the boiler matching the input rate to the demand?

    By the installer. They selects the proper nozzle before commissioning the boiler. That can be changed at any time

    After you make that expensive repair and you still have the same problem, What will you check next?

    Usually from the factory the boiler is equipped with a .75 70A nozzle at 130 PSI of pump pressure for a EK-1F Frontier.

    Like mentioned, the boiler came shipped with a .75 GPH nozzle. The lower firing rates require an inducer fan and sidewall venting for the EK-1.

    Thank you all for your posts. @H2OBandit603 , boiler models like the System 2000 Frontier have an Energy Manager control with thermal purge. This anticipates the end of the thermostat call and purges heat remaining in the boiler to the last zone(s) that called. The combination of thermal purge and low mass means that idle loss is virtually eliminated, and that means that oversizing is virutally eliminated as well. So your boiler will run at very near peak efficiency whether it's the spring or fall with low heating loads, or in the dead of winter.
    Another way to say that is there is no need to change nozzle sizes or downfire to try to substantially gain efficiency (at most is is 1% to 2% different).
    Best,
