Hello DIY,
I've searched high and low for this answer and need some help. I have a three story house, oil burner, hydronic baseboard heaters. all one zone. only have one bleeder on the third floor. the burner is in the basement. and i had to move around the baseboard heaters. (all that went well) I'm having an issue with removing the air from the system. i have tried several ways to remove the air. the heating system was ok before disconnected. the burner turns on and runs for a little bit and then will shut off. about 10 min. the bleeder on the third floor purges air and then steady stream of water, never hot when bled.

Turn off boiler. Close ball valve between circulator and where you have garden hose connected. Open valve to garden hose and feed fresh water to boiler to purge the lines. leave it run for 10 minutes. Longer if your still getting air out after 10 minutes. May want to look if you have isolation valves in your supply line to shut off the other levels that are heating.

Then after your done purging. Open ball valve and turn boiler back on, see if you have heat then.

Thanks been there. I tried this last night when I got home from work. Let it flow for a little while. I still heard some gurgling. I went up to the only bleeder on the top floor and purged the air while it was circulating. Then ran the heater. It got warm. Went to each radiator and they were all warm. Purged the little bit of air. And it's all set!!!
