Portable Camping Stove Design Issue

First post the OP stated..

So I have a popup camper too, with a stove that moves from inside to outside. How nice since there are gas lines in both spots.

I hook the stove up, push the button down to lite, and try to light the burner. Nothing. Check that all valves are open, gas tank full, furnace works great. Nothing.

So, the OP has a popup trailer.

They are using a stove that the builder of said popup installed into that popup.

That stove is deigned to be usable inside or outside the same popup.

Manufacturer of said popup also plumbed in the gas lines, installed quick disconnects to allow the said purpose of being able to move and use that stove from the inside to outside.

At one point in time before or shortly after that popup left the manufacturers facility that stove had to have worked..

As far as I am able to determine, OP has not modified the stove or gas plumbing but now the said stove is not working inside or outside.

Common parts are stove, pigtail from stove to quick disconnect and inside and outside quick disconnects..

OPs furnace works ruling out tanks and high pressure regulator.

Quick disconnects can and do fail as they are pretty much a similar design as quick disconnects you use on shop air lines which tend to fail often.. Doug gave good advice on how to check the quick disconnects.

Is the outside low or high pressure? What does the fitting look like, quick connect or screw on?

If that is a regulator where the copper line is attached, you cannot have two regulators, one at the tank and another in the stove. Possibly the wrong stove was supplied.

Not necessarly true
The RV has a primary regulator 11" of water is the pressure
And the stove often has a secondary regulator at a LOWER pressure.

To the original poster
First follow the lines to insure that both are low pressure ports (I suspect they are but check to be sure) also inspect the lines to the non-working port.

Then it is possible the external port has an issue.

1. You DO HAVE a regulator. Period. While you see the Tank hose at the tank, there IS a regulator connected to that hose.
2. The Gas line at the pic of the Range, that silver thing is the Range Regulator and it is there to drop the RV LP pressure from 11.5 inches to 10 inches which is what most RV Range/Ovens operate at.
3. Clarify, IF the Range is inside the RV in its mount hole does it operate and light OK?
4. It only fails to operate correctly when mounted outside?
5. If mounted outside, can you light the burners with a match?
6. Last, from your pic, there does NOT appear to be a Piezo or auto ignitor system. Your Range must be manually lit with a match or flame. Doug

3. Inside or outside, the gas does not make it to the burner. When I light the gas at the knobs, it lights, but very weakly. There is no hiss from even the opening at the knobs.

I assume you have a spring loaded LP quick connect. It is probably the Center pin inside the quick connect is NOT seating squarely and pushing the inside pin inward to release the LP. You need to remove the FEED fitting(LP turned OFF at tank) and then have someone open the LP tank valve. If you feel and hear a good stream of LP the quick connect is your problem. Doug

PS, VERY common problem when trying to use the outside LP connection, very strange it also fails inside.

Maybe the orifices are clogged, or maybe the stove's regulator is being very much overzealous (or otherwise having the gas supply constricted). If all the burners are behaving identically, I'd tend to suspect things common to all three.

Since the furnace works it's possible you have a clogged or pinched gas line or the regulator in the stove is shot.

FYI, I had a problem with my popup when I tried to use the stove outside. Thanks to lousy design, the hose was connected to a pipe that came straight up from the floor, and it made a 180 degree bend. Routing the hose to the outside the hose would kink and cut off the gas. I had to add a 90 degree elbow fitting to keep the gas line from kinking.

A lot of people, including me, give up on the portable stove that comes with the camper.

Think about a Weber, Coleman, or similar portable camping stove. You may be happier in the long run.

Unlike me, lately.

#2 too much wind?

Yep, that's my problem! :)
