Help Bleeding Convector Radiator

Hi Community! I could use some help figuring out how to bleed this convector radiator in my house. We just moved in and all of the other radiators in the home are baseboard type. This one in the basement looks very different and doesn't have a bleeder valve that I can find. There is a nozzle at the bottom, which looks like can be connected to a hose. Could this be used to bleed the unit? It's currently not heating up, but we can hear the water trying to make its' way through the pipes.

Note: When we first moved in none of the radiators were working, as the water had been turned off by the previous owners when the started renovating. Bleeding all of the baseboard radiators immediately warmed them up. Thanks in advance for any help you can provide!

It doesn't have a bleed valve because the HW line comes in from above and goes out the same way. Air bubbles will rise out of the convector.

If that unit isn't heating, you might try connecting a hose to the valve so as to flush out accumulated rust and other debris that may be impeding the water flow. As a worst case, you may need to remove the convector, after depressurizing and draining the system, so it can be disassembled and have hard caked debris cleaned out.

Thank you so much! I connected a hose and drained about 2.5 gallons of nasty looking dirty black water before it started to clear up. Kicked the thermostat back on it's heating up very nicely.

I'm glad it wasn't more difficult. It'd probably be a good idea to flush it annually at the start of the heating season.
