Alde Manual Bleeder Valves—T@B 400

JEB

Are there manual bleeder valves for the Alde on the T@B 400?  I know there is an automatic bleeder valve near the boiler and I’ve found it.  It vents directly through the floor. But are there manual bleeders in addition to the automatic one?  If so, where are they?  Thanks in advance.

The 320 has a single manual bleeder valve located near the rear fin-tube convector. This makes me think there has to be at least one on the 400 as well. However, getting to it will likely involve digging your way down to the fin-tubes themselves.

Why would you want to?

Read enough posts on Alde international forums that manual bleeding can be helpful to get rid of stubborn air pockets even if you have an automatic bleeder valve.  Yes, I am aware of the other techniques for purging.
