Since October 1998, propane tanks come with an ACME style safety discharge valve. With this valve, many customers experience a similar problem when the fuel level of the LP propane tank gets to the 25% range (25% full /75% empty). They get the burner(s) started, but no matter which setting they turn the burner knob to; they only get a flame that measures ¼ of an inch high or no flame at all. When this happens, customers incorrectly believe their propane tank is empty or low, so they unhook it and bring it to BAUER’S to be refilled with pro-pane. When we pick the tank up to refill it, there is often over 3 inches of Liquid Propane or about 105,000 BTU’s left in the propane tank. What happened is the “excess-flow-limit-device” (EFLD) inside the black plas-tic coupler was tripped. This coupler is attached to their grill regulator and screws onto their ACME valve pro-pane tank. The (EFLD) is the brass metal (hexagon shaped) device inside the black plastic coupler that has a small bebe inside of it. When the gas vapor flows at a normal discharge rate, the bebe stays in the resting posi-tion and allows the propane vapor to flow to the grill burners. If the propane flow discharge rate is too rapid or fast, the bebe is pushed against the decreasing passageway. When this happens, the bebe chokes off the regular flow of propane gas vapor. (This is similar to dropping a pool ball into a gas funnel while filling your lawn mower with gasoline. Only a small amount of gas can get “around” the ball that is impeding the normal flow). To prevent this from happening to you, please follow these instructions:
- Make sure all your grill burner knobs are in the “OFF” position and the propane tank valve is turned “OFF”.
- Slowly turn your ACME propane tank valve “ON” until the rubber hose going to your grill is pressurized.
- Turn “ON” only 1 burner knob and turn it FIRST to the “lowest” setting. After 2-3 seconds, turn it back up to the “high” or “start” setting.
- At this point “turn” or “push” your sparker to ignite the propane. The flame should be at a normal height and you can now select the burner setting of your choice. To add another burner, repeat steps 3 & 4.
Note: if you forget to follow these instructions and trip the (EFLD), you must turn ALL of the burner knobs to the OFF, position and momentarily wait for the gas vapor to equalize the pressure on both sides of the bebe. Once the pressure is equal, the restricted bebe will roll back to its normal resting spot. Repeat steps #3 & #4.
Remember, your “ACME” propane tank weighs 17-18 pounds when it is empty and 37-38 pounds when it is full (18+20=38). Use any bathroom scale to weigh it. Thank you for buying your propane gas from:
