Received a call that the second floor baseboard heat was not operating, upon arrival we found that the baseboards were cold but the pump is operating. There are no bleeder valves downstairs to be able to purge air from the system, I was able to access several air vents between the second floor and the attic and between increasing the water pressure in the system and getting the air vents to manually bleed out we were able to get water flow. There is still a significant amount of air that will need to be bled through a proper removal system, but for now the heat is running and operating.
