Coleman Grill Issues

[aosias]

I have a Coleman Signature Grill from REI- has a burner and the grill section. Runs great on the 1# bottles.

I purchase this:

And a Worthington 5# propane tank.

I connected all of them and turned on the gas- heard gas come out of the grill, burner lit and then it shut off. No gas out of the grill. No gas out of the line. Disconnected all of it and then re-connected it. Had gas for two seconds. Then nothing. When I disconnect the hose from the grill there is no gas. When I disconnect the hose from the tank there is gas.

The tank was filled today.

Am I missing something or is there an issue with my grill? Grill works with the 1# tanks.

Edit: Tried it with the 20# half full tank from the grill. Works great. So, the question now is why won't it work with the brand new 5# tank?


Thanks,
Alex

Is the larger tank sending too much pressure, and perhaps there is a valve that shuts on high pressure?

sounds like an issue with that line adapter if no gas comes out of it but does come out of the tank. Also, if no gas comes out of the line, I wouldnt blame the grill.

I thought the line too but it works with the larger 20# tank. Could the smaller 5# be overfilled and that is causing the issue? The 20# tank is half full.

do you have a traditional grill you could try the 5lb tank on?

Where is the regulator on the grill? Is it possible that, like you say, the 5lb is overfilled and providing too much pressure and the grill's regulator is shutting it down. Maybe just crack the valve on the tank and see if you limit how much pressure is being released (disconnecting the hose from the grill should allow the regulator to reset)

I just did that. Worked great with the grill. Hooked it up to the Coleman and it worked flawlessly. Seems it just needed to burn off some propane. I've also had a cup of coffee and seem to be thinking clearer now.

I had a similar problem with both of the five lb Worthington's I carried at one time and occasionally with a 'regular' twenty pound tank. When I mentioned it to a friend in the propane business, he suggested the problem was likely caused by the Overflow Protection Device (OPD) Valve mistakenly sensing a leak when the hand valve was opened quickly especially if the device being lit had a longer than normal hose. I found if I left the burner valve closed, slowly opened the tank hand valve, cracked the burner valve a bit and then lit it, I seldom had a failure. He didn't have any idea as to why it was more common on the smaller tanks. Sure glad Uncle Sam takes such good care of us with all these mandated safety features.

if that is the case, perhaps the valve works by sensing PSI (albeit in an unsophisticated way), and the smaller tanks lose more pressure per volume than a larger tank would. Speculation though.
