OK, found it based on that article. For the archives--
The screw points towards the boilers, and is all brass with a brass locknut. The locknut is 14mm, the adjuster screw is 10mm. Clockwise/tighter gives more pressure, counter-clockwise/looser gives less pressure. About 1/4 turn is about 1/2 bar. You can just get a box end wrench or small socket on the adjuster. With the pump running, I was able to quickly set the pump to 9 bar with a blind pf, then I opened the OPV until water was flowing from the drain tube into the drip tray. I then slowly closed the OPV until the water stopped flowing, and then closed the OPV another 1/2 turn. This seems like it will give some protection for the boiler lines, i.e. OPV should open just above 9 bar should the pump ever malfunction.
