Weber 41455 20 Pound Tank Adapter Hose for Use with Weber Q and Go-Anywhere Gas Grill

Works great. Be sure to wait the prescribed time (~ 1 minute) after opening the valves - otherwise the supply is reduced to pilot lite strength. I speak from experience. Duh.

the small screw on tanks work very well. But when using the adapter hose on a 20 lB tank the flame is too weak to grill, especially when the outside temp is in the 40s or lower.

I've tried slowly turning on the tank valve waiting a bit before lighting the grill, but the flame is still too low. I'll have to wait til summer before I can use the 20# tank with adapter hose again.

EDIT: After trying the procedure below I'm up and cooking again with full force even with it being 35 degress outside.

BYPASS INSTRUCTIONS
GAS GO ANYWHERE, WEBER Q + BABY Q
Since 1995, all regulators on gas barbecues have a safety device which restricts the gas flow in the event of a gas leak. You can inadvertently activate the safety device without having a gas leak. Typically, this occurs if you open the LP tank valve too rapidly, or if the valve + regulator assembly is in a slightly open position when opening the LP tank valve.
Your must remember when you are grilling you should always do the tank valve first and then the valve + regulator assembly when you start grilling or stop grilling. Never turn off the valve + regulator assembly before the tank. Gas is trapped in the valve + regulator assembly and adapter hose and the next time you turn on the tank, that residual gas in the line will back up and trigger the safety device.

Also, when you start grilling, you should open the tank valve V-E-R-Y S-L-O-W-L-Y, about ¼ turn at a time until it is all the way open before you turn on your valve + regulator assembly to light the grill even is it takes 30 seconds to a full minute. If you've just had your tank refilled, it has a lot more pressure in it at first than after you use it for awhile. That may trigger the safety device sometimes, too. These conditions can be recurring. If it happens again, then you will need to go through the reset procedure again.

If you do activate the gas regulator safety device, the barbecue will only reach temperatures between 250 and 300 degrees, even with the valve + regulator assembly on the HIGH setting.

TO RESET THE GAS REGULATOR SAFETY DEVICE:

Open the barbecue lid.
1. Close the LP tank valve.
2. Turn valve + regulator assembly to the OFF position.
3. Wait at least 5 minutes if the barbecue had been lit
4. Disconnect the adapter hose from the LP tank.
5. Turn valve + regulator assembly to the HIGH position.
6. Wait at least 2 minutes, then turn valve + regulator assembly to the OFF position.
7. Re-connect the adapter hose to the LP tank.

RE-LIGHTING THE BARBECUE:

Open the barbecue lid.
1. SLOWLY open the LP tank valve 1/4 turns at a time all the way open.
2. With the lid open, turn valve + regulator assembly to the HIGH position.
3. Ignite the grill by pushing the crossover ignition button.
4. After the burner is lit, close the lid.
5. The barbecue should reach 500 to 550 degrees in 10-15 minutes.
WHEN YOU ARE DONE GRILLING:
Turn off the LP tank valve first
Turn valve + regulator assembly to the OFF position.

I purchased two of these Weber hoses to connect a 20lb propane tank to my Weber BabyQ. Both hoses worked for about a day or two and then failed (stopped flowing gas). I even replaced the propane tank to see if that was to blame but the problem persisted. The BabyQ works fine with the small screw in camping tanks. Finally I went down to the local BBQ shop and the sales person indicated that the problem with these hoses may be a known issue and that I should contact Weber (of course there is no way to know if this is true, but two failed with me so I am inclined to believe it). I purchased one of their hookup lines and have been grilling happily ever since.

Good adapter ... Save yourself from buying the small propane canisters and hook up your Q to a porpane tank.

This hose is invaluable as it connects to a 20lb Propane tank and probably will last throughout the grilling season. This is my 2nd hose as the first one was chewed thru by chipmonks after one use. I have purchased 2-2 foot stainless steel spring hose protectors and hope they will be able to stop those little critters from gnawing.
