Good afternoon!
I have a Federal gas fired boiler, model number GSFA17, rated at 175000 BTU. It is used for heating purposes only. It is supposed to heat 3 floors. The thermostat is located on the 2nd of the 3. There are 4 rooms on the 3rd floor and 2 have not gotten heat in my time living here (over five years)! Lately, I have also been hearing a draining sound coming from the baseboard heaters on the 3rd floor.
I do NOT see any valves on the radiators that resemble a valve, much less a bleeder valve!
I will get some pics posted as soon as I can.
Any and all suggestions will be greatly appreciated! Thanks in advance.
