Adjust jet ?

Our Dometic refrigerator DM 2652 does not work at high altitude, contacted Dometic and they said to have a propane dealer adjust the jet when going to high altitude, they did not say how to do this. I didn't know the jet was adjustable, if so can someone tell me how. Thanks Lee

Welcome to the forum Lee. There is a lot of great information to be found here.
Sorry but I cannot help you with the flame adjust on your refer. In fact I have never heard of that.
Hopefully someone here can help.

Peace
Dave

Thanks, that is what I thought, could not figure out what they were talking about when they said to adjust the jet.

High Altitude Orifice jet --> a quick search to this page --> http://www.thenaturalhome.com/gasappliances.htm

PS - camping back at a lower elevation would require a re-changeout - PITA - I am wondering if you could swap out LP regulator to an adjustable one and monitor downstream pressure and adjust depending on elevation (ie lower than 6 inches WC).

Thoughts on just runnng on electric till you come down in altitude that is if you have it available?

How about some form of solar power? I would think that it would work enough to run the frig, even if it was a small system.

Don't know anything about solar, but have spent my spare time the last two days reading about it on the internet. I think this might be the answer, if I can figure out what I need.

Since you're going to be there for awhile, why not just go ahead and change the orifice. About $25 and 10 minutes work.

Lee:
I don't mean to hijack your thread, but I have similar concerns both about my LP furnace, water heater and stove, along with my gasoline generator. I have a trip to Yellowstone planned in conjunction with the National Heartland Rally this spring/summer.
I guess my question is to everybody else who has already stayed in their Heartland's in the Yellowstone or other high altitude areas: Did your propane appliances work O.K., or did you have to go all electric???

OK you have convinced me to change the orifice, contacted Dometic to get a different one. They say the one in the fridge is the only one that will work, and they don't have any others. They say the problem is propane pressure, have checked that, also had the dealer check it, it is fine. So where do I find a different orifice that will work if the mfg, don't have one.

Usually your larger propane dealers will be able to make the change for you. Give them a call and they might have an orifice.

You might also check with a mobile service tech of any HVAC shop that deals with propane furnaces. Twenty years ago I owned an HVAC shop and would convert new natural gas furnaces over to propane to install in rural areas. This was always done with manufacture supplies parts. My thoughts in this day and age any shop would be hesitant to alter a manufacture supplied item not wanting the responsibility of something happening.

I know that from working with the gas guys (I did the installs), they do have those orifices that they can drill out. Maybe they can find the proper hole size.

I would talk to RV Mobile Inc., who are RV refrigerator specialists.http://www.rvmobile.com/
Go to this webpage: http://www.rvmobile.com/Store/Begin.cfm , look down at the bottom left and click the "Search by refrigerator part type" menu, click on "orfice", you will get a listing of the orfices they have. The 2nd and 3rd ones are listed for high altitiude.

I am thinking about getting (or making) an inexpensive manometer to check/adjust the gas regulator at high altitiude.

Here is one of my post from last year that you might be interested in.

You can easily make a water column pressure gauge. I made mine 24 inches tall and made hash marks on the board 1 inch apart. I then fastened a 5/16 tygon tubing on the board in a U shape. My tubing is 5 foot long. To use fill the U with water to about 11 or 12 inches then lift the range burner cover and slide the other end of tubing over burner orfice and turn that burner to high. Count the hash marks between high and low point of water in U and that will be the water column pressure. You must have another propane user on at the same time to remove static pressure such as oven or furnace.//heartlandowners.org/attachment.php?attachmentid=12007&d=1297716353&thumb=1​
