enerjet 14,000 btu gas furnace
I just removed all the air from 2 upper zones in the furnace. I changed the the expansion tank, as well the air release valve. All air problem are gone. The furnace is 16 years old, and has 5 zones on it, that only 4 are on all the time, with the 5th being the basement, used rarely. Now when the furnace turns on, I hear a sound of boiling , rumbling from the furnace. I cannot contact enerjet, they are out of business. I keep the temp of the furnace@ 180. Can anyone help me fix this problem, PLEASE
