Building a Chimney for a Kb8 Boiler

Your Keystoker is a long ways from the oil converted coal boiler that my parents had, but I think they went thru every couple weeks or so and used the key to bleed the air out of the radiators. They would get real hot after that.

I'll keep bleeding

Slope the radiator towards the air vent, see if the top of the radiator is as hot as the bottom. If not, it definitely has air in it.

Got a little more air out this morning.

I tried tipping it both ways, and bleeding it, but didn't find any more.

I'll bleed again tonight.

I can't imagine what it weights now that it's full of water!

Can I just add a elbow, and automatic bleeder, Like the one on my air scoop?

In your picture, we see the side of the radiator that does not have the bleeder. That is the supply side right? The bleeder needs to be on the return side.

I have mine sitting with the bleeder side/return side slightly higher than the supply side. All the air came out of it with no problem in a few minutes.

I did. Return and bleeder should be on the same end, and that end of the radiator should be slightly higher than the opposite end.

Yup, bleeder is on the return side. I got lucky I guess.

I'll shim it up.

Thank you.
