Boiler Pressure Reading Too High — Heating Help:

The second thing I noticed was a high pressure reading on the boilers pressure gauge (8 psi). So I changed the 2 main air vents assuming they weren't getting enough air out of the system and set their subtractive Honeywell pressuretrol for a cut-in of .5 psi and cut-out of 2 psi. But the pressuretrol never actually shuts the boiler off.
