Presumably you have the proper test equipment to perform all the startup sequence?
Without knowing a lot about the rest of the system I wouldn't care to specify a pump speed…

which boiler do you have? Which circulator? What size boiler piping?
Some answers in this chart.
What temperature are you running the boiler? With a wider delta, slower pump speed, you may put the boiler in Condensing mode, return below 130. Which increases efficiency
The manual may indicate the widest delta, sometimes 30 35 degrees is allowed in fire tube boilers.
