We installed several PF850 boilers on different projects, and are experiencing high gas pressure switch tripping out.
One of the projects we have installed a lockup gas regulator and set for 6"WC. The high gas pressure switch factory set for 13.5" WC will trip randomly sometimes will work for several weeks, before the next time it trips out.
Another project is on a Low pressure gas service only has incoming gas pressure of 5"WC and the High gas pressure switches trip out on this installation as well.
Anyone else having these issues, what have you done?
