PROBLEM COMPONENTS SUGGESTIONS
The system will not open
and allow fuel to pass. Fittings and valve
connections Check pressure gauge on termination fitting to ensure the proper pressure
is being applied. If not pressurize and evaluate.
The system seems to be
losing nitrogen pressure. Fittings and valve
connections Pressurize the system and perform a soap test on all fittings and joints in
the system.
The system is holding
nitrogen pressure, however,
the fuel will not flow. Valve Check the manual valve located on the bottom of the LineGuardian valve
body and ensure it is in the open position. Ensure that the fuel system is
holding a vacuum. Check all external fittings and the fuel pump.
The system seems to be
loosing nitrogen pressure
slowly. Eventually the valve
closes and stops the fuel. All components This problem usually indicates there was a problem installing the polyamide
tubing during installation. You should verify with a soap test that no fittings or
joints are leaking. You may need to redo the polyamide connections at one
or both ends of the system.
The pressure gauge on the
termination fitting seems to
indicate different pressures
at different times. All components Although the pressure applied is enough to open the LineGuardian valve,
if the temperature drops, the pressure will drop as well. Check for leaks by
performing a soap test. If no issues are found after the soap test, then it
may simply be a symptom of the lower temperatures. If the LineGuardian
valve is closed, add more nitrogen to open.
The system will not charge
with nitrogen. All components Perform soap test. If need be, replace the Schrader valve on the
termination fitting.

COMMENTS/ACTION REQUIRED
1
Correct installation, system is fully operational
2
LineGuardian system is functioning correctly, but there is a vacuum
leak in one of the external fittings. Check fuel fittings at the tank
and burner, as well as the fuel pump for vacuum leaks (see #9 in
“Verifying the Installation”)
3
There is a nitrogen gas leak within the system. Check CSST and
fittings for leaks using a soap test. Retighten all fittings and if
necessary re-install to remedy the situation (see #7, in “Verifying the
Installation”).
4
There is an internal leak within the LineGuardian system. Check
the polyamide fuel line for damage or imperfections, as well as all
connection points to ensure a proper seal is made to both the valve
and termination fitting (see #8, in “Verifying the Installation”).
