HOW A QCC VALVE WORKS
There is a safety check valve inside our bright green QCC-1 fitting. Once the regulator is connected to the
propane tank and the main cylinder is “OPEN”, a minimal amount of gas is allowed to flow through the
check valve. If there are no downstream leaks, the pressure on both sides of the check valve will equalize
and the spring loaded stopper will open allowing maximum gas to flow. This only takes a few seconds to
complete and then you can start the lighting procedure.
IF THE QCC INDICATES FAILURE
If there is a downstream leak, or if you have started with a control valve “OPEN”, the pressure will not
equalize on both sides of the QCC check valve and it will fail. The only gas flow you will have is a small
amount that is designed to flow around the check-valve, the equivalent of 5,000 BTU’s. This may allow
you to light part of a burner, but not much more. When you open a control valve to light another burner,
you will not get any additional flame and may experience a blow out where none of the burners will light.
In case of a QCC failure, follow procedure below:
TO TROUBLESHOOT THE PROBLEM
CHECK:
1. Check that all of the control valves are in the “CLOSED” position.
2. Check that you are using at least a 30# propane tank
3. Check that you have lava rock in the grill
4. Check that the QCC is lime green - black or dark green will cause lighting problems.
If everything is correct, reset the system.
SOLUTION:
To reset:
Close all of the control valves on the grill & close propane tank valve.
Then start the lighting procedure from the beginning. If the problem persists, Check for
Leaks:
If you experience a QCC Failure, first check your system for leaks:
1. Turn off all control valves and turn off propane tank
2. Extinguish any remaining open flames
3. Let gas dissipate until odor is no longer detected
4. Make sure all control valves are closed and gas tank valve is off
5. In a spray bottle, mix together dish soap and water
6. Spray the following with soapy water mixture
a. Tank Valve to QCC (part that screws into tank from regulator)
b. QCC to Regulator
c. Regulator to Hose
d. Entire hose
e. Hose to Grill
f. Each Control Valve where it Connects to Manifold
g. Manifold end cap (opposite side from hose connection)
7. Turn on propane tank
8. Inspect each connection and length of hose for any bubbles being produced
9. If bubbles are detected (bubbles indicate gas is escaping), turn off propane tank
and call Big John Grills to order replacement parts. Do not go to your local
hardware store.
10. If no bubbles are detected, check to see if propane tank is empty.
11. If tank is not empty, please call Big John Grills for further assistance
