Solenoid Valve Leak Test
1) Shut off the outlet isolation valve. The inlet isolation valve should be
open. Start the vaporizer and allow it to heat up until the heaters shut off.
This allows any accumulated liquid in the vaporizer to be forced back
toward the supply tank.
2) Disconnect the vaporizer by shutting off the power at the disconnect.
Shut off the inlet isolation valve. Cautiously bleed off any LPG pressure
in the vaporizer and outlet supply piping. When the pressure reaches no
pressure in the vaporizer, remove and then reinstall pressure gauge and
verify 0 pressure.
3) Turn on the inlet isolation valve. The solenoid valve is closed and you
should not have any pressure build up in the vaporizer. If pressure
increases, the solenoid valve is leaking and needs to be repaired or
replaced.
