    Gas does not pass through the regulator.

  • dmanuel May 26, 2008

    There is a small (vent?) hole in the face of the regulator. Propane gas escaping from this hole self ignighted when its gas reached the open flame from the burners positioned in the grill above. I was able to turn the valve off and extinguish the flame. 25 May 2008

    My Weber Spirit 500 regulator was blowing propane out the vent hole also. I am amazed by the ninnies posting inane comments about this being normal or don't get the facts right.

    I had the burner on and my son walked by and smelled the propane. The regulator was blowing it out the regulator's vent hole big time. Ok, so people reading this: IT WAS THE REGULATOR"S VENT HOLE, not the tank, not the manifold, not the burner, the REGULATOR. LOOK at your own regulator: IT WAS A SMALL VENT HOLE!

    Weber quick disconnect regulator started leaking throught the vent when I replaced my tank. I found that if I turned the burners on and covered the vent hole, I could hear propane really gushing out of the burners. Fortunatley I did not ignite the burners. Got a new one from Amazon as Weber had them back ordered.

    Same issue with gas coming out the vent hole of the regulator. Tapping on the regulator lightly with a plastic object seemed to stop the leak at least temporarily but looks like I'll need to find one somewhere. Found one online but it included the hoses and was $46. Would like to find one for 1/2 that.

I went to Lowe's and bought a replacement regulator (I am not at home so I can not cite the model number - but drop me a note if you need it) and using the adapter off the original regulator, it works like new.

Replace the regulator as this is typically an issue where the diaphragm has separated from between the body and bonnet. This is not repairable. There is no recall for this as was in the case of the 450 regulator as it is a manufacturing variance that happens with all products. It passed initial QC, but in time the diaphragm moved.

Marshall valvestate 8040 - how to change the valve?

Hi chagzuki, you are right, but only when the valves are used as outputs, You amp has transistorised outputs, and a single tube used for distortion/gain. You will get a very long life out of this tube also because its supply voltage that is is used in the valvestate preamps is really quite low. Just enough for it to work really, so the tubes life can be expected to be much longer than normal. It is also a preamp tube, not an output tube, so they rarely need changing. If you ever did want to change it(dont bother), it is located on the PCB inside the unit. You have to slide the sleeve off to get at it. Get yourself a JCM800=the best guitar amp ever built(imho), then yo got pure Marshall tone, and output tubes that need changing every 6 months or so. Now go RIFF OUT and dont worry about your valvestates' "valve"

Since 1995 all regulators (the part that attaches to the gas tank to regulate the flow of gas) have included a safety device that restricts the flow of gas in the event of a gas leak. This safety device can be inadvertently activated in two ways, putting the grill into what is commonly called “bypass”. The first way for the device to be activated is to leave one or more burner control knobs in the “ON” position when the LP cylinder valve is opened. The second is not to wait long enough to “start” the grill after opening the LP cylinder valve. The safety device in the regulator is activated each time that the LP cylinder valve is opened. The device resets itself when the gas pressure equalizes between the closed burner control valve and the regulator, through the hose. If a burner control knob is turned on before the gas pressure can equalize, the device will remain in “bypass”. The length of time necessary to wait to “start” the grill after turning on the LP cylinder valve is dependent on the length of the hose and outside air temperature. It is always good practice to wait a few seconds after opening the LP cylinder valve before turning on the burner control knob to start the grill.
Keep in mind that the safety device reacts to a gas leak. If a grill is in bypass, the gas connections and hose should be tested for leaks with a soap and water solution.
If the grill is in bypass, after checking for gas leaks do the following to get the grill out of bypass:
To reset the gas safety device:
Open the barbecue lid.
1. Close the LP tank valve.
2. Turn your burner control knob to the OFF position.
3. Wait at least 5 minutes if the barbecue had been lit, then
4. Disconnect the hose from the LP tank.
5. Turn your burner control knob to the HIGH position.
6. Wait at least 2 minutes, and then turn the burner control knob to the OFF position.
7. Re-connect the hose to the LP tank.
Re-lighting the barbecue:
1. Open the barbecue lid.
2. SLOWLY open the LP tank valve all the way and wait 1 minute.
3. With the lid open, turn the burner control knob to the HIGH position.
4. Ignite the grill by pushing the crossover ignition button.
5. Close the barbecue lid.
6. The barbecue should reach 500 to 550 degrees in 10-15 minutes.
When you are done grilling:
1. Turn all burner control knobs to the OFF position
2. Turn off the LP tank valve last.
* Always follow the re-lighting instructions whenever you use the adapter hose and larger tank.
