Periodic Checks
Slowly close the outlet slam-shut and check line
pressure between it and regulator . A slight increase
in pressure should be detected: this results from
overload due to closing, and is followed by pressure
stabilization . If, however, outlet pressure continues
to rise, then seal is defective . Check if leak is coming
from regulator or pilot, and service .
