Propane tanks equipped with the Q.C.C. {quick coupling connector} have an internal excess-flow valve
safety feature to prevent propane from escaping at full pressure if a gas hose is severed.
If the hand wheel on the propane tank is opened too quickly, the excess flow valve could close causing
the propane flow to slow down or stop. The heater will appear to 'burn' properly for a few minutes, the
flame will diminish and finally extinguish. Attempts to relight the heater will fail.
If this occurs: Close the hand wheel on the propane tank and let sit for a few minutes. The excess flow
valve will then reset . Now turn the hand wheel on the propane tank very slowly to prevent
the excess flow valve from closing again. After one complete turn, open hand wheel on propane tank
all the way at normal speed. Heater should now be OK for normal operation.
