Here's the scenario. I have a friend with a hand fed coal boiler. The circulator needs to be replaced and he even has one ready to swap it with. The trouble seems to be, according to his wife, they can not find the air bleeder valves on the system. He's afraid to swap the circulators for fear of getting air in the system and not being able to bleed it.
So, first question. Is it even possible to not have bleeder valves on a boiler system?
Second question, where would the air bleeders be? Wouldn't they need to be at the highest point? Or doesn't it work that way?
Sorry for the boiler 101 questions lol. I don't have much experience in the hydronic department. They are currently burning the black liquid but would like to fire up the coal boiler, especially for this cold spell.

Thanks for your help, so it could be anywhere in between the boiler and last baseboard then. If there is no purge valve, I would look around the baseboards to find a bleeder valve? Do I have that right?
Where do people normally put these things?

It isn't a problem, no need to bleed. Change the pump and fire it up.
