At the very least, you want to plumb the amal valve back in.

If the amal valve is still present, plumb it into the mains, plumb the inlet manifold into one side of the amal valve, and the actuator into the other side. The Escos has a different amal valve to a Sierra, so make sure you get one of those.

Then send the bleed valve to one of those pikey metal merchants on TV like wewantyourgold.com.
