Propane question?

Thanks Itat, I appreciate the video.

But what has that have to do with saying the OP's tank was mounted wrong? Two entirely different scenarios. Oh, well, neither has anything to do with solving the OP's problem.

Certainly sounds like a gas supply issue. The Tee that the dealer installed might be defective or the actual line feeding the BBQ might be too small to allow it to run. The MH has a two stage regulator in the OP's picture. Some of those on the grill regulators need maximum pressure to operate as well. The best way to troubleshoot is to get a certified Propane technician to measure the pressure available at the output of the BBQ regulator and see if it dips when the stove turns on.

But where the T is, it should get full pressure directly out of the tank before anything in the unit gets any propane. It sure is a puzzle to me.

I have no expertise on LP tanks but I do know that LP tanks for residential use are horizontal with the valve on top. That's probably the type of tank that cgotto1204 is familiar with. In fact, the vast majority of LP tanks seem to have the valve on top but motorhome LP tanks seem to be the exception.

Maybe somebody who actually knows something about RV propane systems can help the OP.

[cgotto1204]

OldCoot, if the tank was mounted wrong and liquid propane was in the lines, then there wouldn't be enough space for the propane to vaporize properly. Thus resulting in not enough pressurized gas to sustain both the grill and the RV stove.


If the tank is mounted properly, then it may be that there is a faulty valve on the tank that is restricting the flow. I would tear apart the connections to ensure that there isn't any dirt or damage.

[cgotto1204]

From a technicians point of view, with-out physically examining the unit, I can only give advice as to the cause. You would think after 13+ years in the Navy and 15+ years after, I would learn to ignore questions.

[OldCoot]

cgotto1204, the tank mounting is not the problem and I am fully aware of the liquid/gas situation. Grill works fine until stove is lit is the problem, so the valve should still allow the first line to receive gas regardless unless the valve is not completely open or is defective. Could be a defective valve AND the grill hose is too small and the main line to the camper is much larger (generally 1/2" black pipe.

X2 on the hose as well.

[cgotto1204]

Itat is correct. With-out physically examining the system and checking the pressure and flow out of the tank or the psi at the grill and RV stove, I can't give an answer. The OP should have the system inspected by a qualified technician.

Where is the regulator for the grill? I can't tell, in the pictures. Does the 1-pound bottle screw directly into it?

Does your trailer have a quick-connect hose but you added a different one to get high pressure, rather than the low pressure supplied by the quick-connect?

Have a look at the tee off the tank, high pressure.

Now that I'm reading this on my laptop, not on my phone, I can see it's providing high pressure. Does the trailer have a low-pressure quick-connect gas hose on the awning side, as many do?

[Trail blazer]

Yes it is providing high pressure from the on board tank to the grill. At the grill, there is a regulator where the one pound bottle screws into. The line from the onboard tank screws in there.

The vapor outlet valve on Class C propane tanks are on the side. They have an internal tube that takes vapor from the top of the tank.


The original poster may have a problem with the excess flow valve. It's part of the vapor outlet. It shuts off flow if the flow is above a certain rate. This is intended to shut off the gas if a line breaks.

I will take to the dealer as the unit is still under warranty.

[Trail blazer]

Thank you everyone for your help and advice!!!!

[I]I would say that the most likely problem here is the regulator within the gas grill. Many gas grills that directly use the small gas cylinder have rather poor regulators. My thought is that the gas grill regulator is sensing the pressure drop and shutting off the propane flow. I would try a different grill ideally one with a large regulator built into the gas line of the grill before taking this to the dealer. If the problem turns out to be the added gas grill you may be charged by the dealer for the trouble shooting since the grill is not part of the coach and therefor not covered by the warranty. I]

[Trail blazer]

Ok. Will do. Thank you.

The 2013 3010DS came with an external hook up for the grill. Did they not put it in the newer model?
