Have you considered that it could be defective? Just replace it.

That will be done once the kids are back from Canyonlands —14 hour drive. I've been attempting to determine if there is a field fix. Besides, Dometic has said it is normal (to the RV builder and others who have had the problem). I KNOW from experience it is not generally normal. So I am looking for a fix. Have asked Dometic to send a new regulator pipe assembly. Weeeelll see.

A few years ago I was on a trip up at an elevation of about 5,000'+ when my Dometic 3 way r efrigerator would not provide much, if any, cooling on propane and produced a low burner flame. Contacted a mobile rv repair guy who checked the problem out and said the propane gas regulator needed to be adjusted to a higher level. He reset the pressure regulator to I think 15psi. The refrigerator worked great after that. I was told to reset the regulator to 11.5 psi once I returned to a lower elevation where I lived at about sea level. Did that after I got home and everything worked fine. By the way, I did ask other rv hers if they had any issues and they said they didn't so I guess I was the only one with that issue. Also, my other propane fired appliances worked fine before and after the adjustment of the regulator.

Just to update my interaction with Dometic. While failing to find the regulator tube part on line, I went back to Dometic. They said that 50806 was no longer available. I said its a new unit! Then the person looked further and found that that part has been replaced by a new part 50817 which is a whole burner assembly that includes the regulator tube as an integral component! It's covered by warranty. But while I can buy it on line, I can't get it from Dometic because it's a gas part! The unit will have to go in to an authorized Dometic dealer! Remarkable. All this time to find that it is a defective part! As it had to be, given that the 4500 feet stuff was pure BS! BTW Ernie, what instrument did you use to reset the regulator?

enahs: I purchased a "Gas Pressure Test Kit" made by Yellow Jacket, part #78060,0-35"W.C. It came with all the fittings I needed. Don't remember the price but I'm thinking it was $55? It has paid for itself many times over.Good luck.

I camp at 4500 to 5500 all the time and have never had an issue except once. it was when the main regulater was starting to go bad so it wasnt providing enough pressure to the stove when something else like the fridge was running. the stove did light but it looked bad, thin yellow flames and such. this might not be your issue but worth talking a look at it while your at it.

Now things have suddenly gotten a bit cloudy. For a week the only issue has been the stove — no gas at all, which made me suspect the regulator at the stove not opening. Now, last night, for the first time the furnace would not stay lit. Beginning to suspect the main regulator at the tank (or both regulators). All this stuff is brand new. Very frustrating.

I frequent the Escape Forums and actually do not recall a Dometic stove top mentioned. The Suburban gets lots of mention however.
LOTS of gas devices use a second regulator. My propane powered Onan generator has a very large diaphragm regulator in the housing, but gets its gas from the regulator at the cylinders. Stoves do too.
I carry a portable butane single burner and a electric hot plate with me to cover all possibilities.
I think your question is worthy of some discussion on the Escape forum as you have a lot of people with the same equipment on there.

Have been talking with Escape. They are interested and willing to be helpful. Dometic has given them the same altitude response. Kids are back to lower elevation and stove is working but the furnace isn't. This will get more discussion on Escape. BTW, it was on the Escape forum that I first discovered the altitude issue with the Dometic D21 cooktop. There has been no final resolution. I resorted to this forum (as I have in the past) because of its larger, diverse brand membership. OTOH, Dometic is widely used. Meanwhile, I've managed to learn exactly how a regulator works, and it is clear that a number of things can affect it. Some "experts" insist that altitude can affect the air/fuell mixture and thus the efficiency of the flame but it does not affect the regulator itself. Others say it can affect the regulator diaphragm since the regulator is not closed to the atmosphere. But clearly atmospheric pressure does affect something more than the flame quality. In this case (and others), there was no gas flow at all, suggesting the regulator had closed due to insufficient pressure on the primary or secondary sides or both.

A little clarification on pressure readings. When pressure is measured it is normally gauge pressure. That means that it is the difference between atmospheric and supplied pressure. The regulator supplies a set pressure above atmospheric pressure. As atmospheric pressure changes the absolute pressure changes with it but the gauge pressure doesn't.
It isn't the gas pressure that changes with altitude but the amount of Oxygen in the air that changes which causes a rich mixture. The change can cause a less efficient burner but it shouldn't be enough change to keep it from working till much higher elevation.
With this being a new camper I suspect that there is some debris in the system that is causing the problem.
