[C320-list] New Propane tank & now need new supply pig tail, regulator & gauge.

[Guy Smith]

Hey Frank,

The after action analysis was that the regulator failed and sent full
pressure to the solenoid. The old generation solenoid could not handle the
pressure and allowed full pressure to the stove (maybe 100 psi at that
point) go to the stove, even though the solenoid switch was in the off
position. The stove is designed for something like 3-4 psi, so the burner
valves seal blew. When I talked with the tech from catalina direct about
replacement parts, he said they recommend replacing the regulator every 15
years.
>From the CD website:
2) Industry norm for regulator replacement is every 15 years due to
degradation of internal components including the critical spring and rubber
diaphragm. Regulator must be replaced immediately if it has been underwater
or if you smell propane at the vent. Older regulators are potentially
hazardous, so if your regulator is more than 15 years old, replace it.
