We have a Bell&Gossett Anti-Syphon reducing valve set, No. B8, set at 12 lbs according to the metal tag on it. I'm afraid to vent the radiators because I don't understand how to manually allow more water in if the value should happen to not open up. On our other system, we have the lever that folds over the top. Should I trust it to allow more water into the system after I vent air from the radiators? Is there a way to manually add water?

The factory setting of the valve can be easily changed in the field. All you need is a small open end wrench and a screw driver. See our manual #V55999 at our web site, www.bellgossett.com The lever that folds over the top is a quick fill handle. It holds the PRV wide open for quicker filling of new systems. Never leave the handle in the vertical position. Normal operation is in the horizontal position. You can vent air from the system while the PRV adds water to make up for the pressure lost in venting. After you're through, close the shut off valve.
