Propane Question

[zengirl]

Ok, I have a new hose and filled tank yesterday with propane. When the guy started to fill the tank I saw him release the valve with a screwdriver, however, I wasn't there when he finished filling the tank so I don't know if he closed the valve. My problem is my stove burner lights for 4 seconds and the flame goes out. I've never had a problem before and I'm only guessing it's air in the line. I've had air in the line before and it took very little time to dissipate. I've been trying since last night to light the burners. No luck. If I attempt to close the valve would air on top get released or would I lose propane? Any suggestions? Thanks for all your help.

If he didn't close the valve your tank would be empty. Why did you need a new hose? Your problem might be the solenoid.

Propane is heavier than air so it sits in the bottom of your tank. In order to get in down the lines it is pressurized inside the tank. The guy filling your tank will not be responsible for pressurizing your system as he doesn't know what was left turned on so the likelihood is that he has left the tank valve closed which is why you're not getting any propane.

Does your tank have a pressure gauge fitted ?(if not it would be wise to get one for leakage testing - not very expensive) When the tank is full and for most of the time it has propane it it the gauge will have a reading of over 100 - 150 psig with the valve open. If the gauge is registering propane at this level then you should get propane at the stove outlet, provided the stove itself has it's own valve open (not just the hob, but there may be one in the propane line before, or as, it enters the stove base.) If there is pressure registering at the tank and still no propane at the burner, you may have an inoperative solenoid, a blocked line or burner jet or worse still a big leak in the line before it gets to the burner - suggest you get a propane guy to fix it.

OR... try it on another appliance... a BBQ or something that takes propane..

I assume the valve that was opened with a screwdriver is at the top of the tank. This is the vent.Many operators fill the tanks this way. Once the propane comes out of the vent hole the tank is at its maximum capacity. They then screw in the vent screw and then shut the tank with the valve on top and remove the filler hose. In the US all tanks must have OPD's and using the vent method of filling ensures the tank is 80% filled. The maximum with an OPD.

Either the OP did not open the shut off valve when connecting to the hose, highly unlikely but possible or there is another problem, solenoid, or something else.

The excess flow safety valve probably shut off. Turn off the tank valve, maybe even raise the tank an inch or so and drop it, and then SLOWLY turn on the tank valve. If you hear a click, do it again. May have to activate the solenoid valve first.

Just going with the simply things first. Is the manual valve on top of the propane tank open? That caught me once.

The vent screw if left open would vent propane and you would I think notice the odor when reinstalling the tank or when transporting in the car.

I would check the gas soleniod / wiring to make sure nothing is corroded or not working.

There are two valves on top of your tank, the big knob opens the fill/supply valve and a screw driver opens the vent valve. You would know it if he haven’t closed the vent. You do not want to open the vent now that the tank is full.

Propane is a liquid as it goes into the tank. Just like filling a water tank, the propane tank needs to be vented to let vapor out as the liquid goes in.

Thanks to all for responses. It ended up being a faulty new hose. However, I did purchase a new solenoid, regulator and extra hose for backup. So I'm glad it all happened.
