Hello and welcome to Just Answer. If you have any questions after I give my answer just let me know
Yes you are on the right path but in order to get the air out you also have to increase the water pressure to around twenty five pounds. do one circute at a time. and yes the valve below the garden hose needs to be closed while doing this.

How do I increase the pressure? There must be a pressure valve I can adjust...???
Yes look at the fresh water supply to the boiler there is a bell shape control with either a handle on it or a bypass valve that goes around it . If the control has a handle on it just lift it up and it will put the control into bypass.try to keep the pressure up while bleeding the air out. after your done just dump some water ont to lower the pressure back to 12 lbs
Ok, I followed the feed line from the water supple and it does pass through a watts regulator bell shaped valve. The handle on the top has slight resistance when down and no resistance when stood verticle. Can I assume this is the bypass position? Ironically, since the boiler is not calling for heat or hot water, the pressure is at zero. Normal?
No shoud be at aroud twelve lbs
Thought so, boiler bleeding to zero didn't sound right. Ok, so the valve position straight up should be bypass? Almost last question, by purging, would this correct the zero pressure issue? If not, why would it bleed to zero?
If pressure doesnt hold possible cause would be a leak.
Then I should see water....everything is dry. We have heat, just noisy. Leak meaning water? Air?
Ok, you have been helpful and I thank you. The Watts valve we talked about, the lever up is bypass?
Ok, first experience with this site and you have been helpful. Thank you and have a great night!

I will, good night.
