Quick help need on location for additional valve to bleed air

I am in the middle of a kitchen renovation and I need to drain the system to remove a baseboard. Since I was told previously that my system does not have a valve in the correct place to properly bleed it I wanted to add one while the system is down. I need your advice on where to add an additional bleed valve. Should I add one for each zone also? Any help you have to offer would be greatly appreciated.

The bleed

At the highest point of that loop or just before it goes down to the basement.
While it's open, put one on any other high spot preferably just before it goes down. Manuals are simpler, as you will only use them once or twice a year, or after maintenance.

Ken, what was the outcome of your previous thread?

Did you get that all sorted out?

Boiler filled?

Pressure OK?

Expansion tank OK?

Pressure reducing valve OK?

Verified that gauge is accurate?

How did you stop the noise? I didn't re-read everything, but I thought a little history of your system and the issues you were having would help:

As Sid has stated, where the elbows turn to go down, at the 'downstream' ends of the runs is the best spot for bleeders on the baseboards.

But, I think you may be talking about where on the boiler piping to install a "PURGE STATION", is that correct?

Here's where you would want to add a 'purge station' to be able to fill and purge air from the loops.



To purge loops, as always, turn boiler OFF and allow to cool to 100F or less.

CLOSE 7

HOSE ON 8

CLOSE 4 or 5 (first one, then repeat for the other)

OPEN 8

LIFT FAST FILL ON PRESSURE REDUCING VALVES till no more air exiting hose.

LOWER FAST FILL

CLOSE 8

OPEN 7

Water will come in green fill line, through boiler, up supply, through zone, down return, out drain.
