being a scatterbrain and I run out of oil on a regular basis, I've bled my Carlen oil burner numerous times. But I'm trying to bleed my mom's Riello Mectron M5 and for the life of me nothing looks like a bleeder valve... and the manuals are no help. Any suggestions? Thanks!

(hope this isn't a repost. I got a blank page after I hit next)

Here's some more info:

The manual is worthless in that it shows NO such valve and the instructions I read here about an M3 burner just aren't clear enough given the warnings I read in other forums about the pressure regulator being in the same place. I uploaded some pics...

In this pic the only candidate I have is the silver bolt beneath the black one but it is described in the manual as Pressure Gage Fixing Point... not a bleeder valve. It's roughly at the location mentioned in the other post. But I want to be sure. Here's another view..
