When our Alde is cooking on propane it really rumbles. I've seen one comment that insulating the exhaust helped a little, but not many more comments than that. I don't know if we have an altitude issue (fuel ratio? We often camp at 8000ft), settings issue, or what. With our dealer gone (they wouldn't have been much help anyway), should I contact LG, Alde U.S. (Portland), the nearest maintence shop (a Freightliner truck & RV place 200 miles north), or Alde Sweden (which I've done before). Note the pump is as low as it gets...

Thank you for contacting Alde!
So where I think the problem is that you get much above 6500 feet or so, we
can't handle that kind of elevation. We are currently working on some high
altitude testing, but as of now, I don’t have an easy answer or fix.
Is there any way you can use the electric side? It should work fine even at
40 degrees outside.
Let me know if you have any other questions!
Thanks!
Joe

I'm surprised to hear that! 6500 feet?
That's pretty silly.
Maybe they're confusing feet with meters. B-/
Durango, let us know if you hear different.

Get down to around 5,000ft msl and the rumble goes away, almost. Sort of embarrassing when it sounds like you have a sub-woofer cranking away while camping.

When you guys come up with a solution, I'll be sure to share the information with Pleasant Valley so they can keep up with the "new stuff", just as Mike and I do with other modifications.

I'm wondering that if you increase the pressure at the regulator, how it would affect the fridge, since it already has compensation for higher altitudes. By recommending going on 110v power for the Alde at higher altitudes, I don't think Alde understands the amount of boondocking Coloradans do where the mean altitude of Colorado is 6,800 feet.

Hi John,
Thank you for contacting Alde!
So the issue that you are finding is due to the high altitude. Because of
the lack of oxygen, it will tend to pop and roar.
There are no "high altitude' adjustments. The soot is a result of the high
altitude.
We are currently working on some high altitude ideas, but have nothing to
share at this point.
Lowering the pump setting WILL NOT affect this at all. Turning the pump will
only quiet the pump but may cause you to lose some heat effiency.
Your pump is set correctly.
Insulating the pipe won't change any of that either.
Let me know if you have any other questions.
Thanks

What's the difference between them?... I wonder if we have enough tech know-how among us to work out a solution (Although Alde should probably get out of the lowlands of Seattle/Sveden, and work it out).
I wonder if a fan on the air intake, slightly pressurizing the incoming air, would increase the O2 content in any effective way. Just a thought.
How about experimenting with the propane supply to the Alde, reducing the LP pressure? source3 or Durango, do you have an adjustable propane regulator on your Tab?

More clues on the Alde vibration problem at higher altitudes. Two weeks ago I camped at 5,300 feet elevation. Nighttime temp 32. Alde worked fine with no unusual noises. This weekend camped at 7,350 elevation. Nighttime temp 36. LOUD vibration noise at this higher altitude. So loud, I was concerned I'd disturb nearby campers. However, the Alde made the loud noises only at lower temperatures. At 5:00 am, with the temperature at 36 degrees, the Alde was really loud. However, at 8:00 am with temperatures in the mid 50's there was no noise at all.
The vibration noise sounds like its coming from that 2" black plastic flex hose going from the Alde unit to the outside wall of the camper. That flex hose actually covers a solid pipe of some type. Looks like there should be a 1/4" space between the solid pipe and the flex hose. I'm guessing the solid pipe is the exhaust, while the space between it and the flex hose is the fresh air intake (take off the vent cap on the outside to confirm). My vibration noise was clearly coming from a section of the flex hose that was laying on the solid pipe within. If I gently raised the flex hose a little bit at this area, the vibration noise was greatly reduced. I'm no expert here, but I'm guessing at the higher elevations with lower temperatures, the intake flow somehow gets screwed up by the flex hose restricting the intake at the point it lays on the solid pipe within.
Another experienced camper suggested contacting the Alde factory to see if they make a propane "jet" set for higher altitudes. He also suggested trying to keep the propane tank warm at the higher altitudes.
This is a serious problem with the Alde. Hopefully, the factory people can offer a practical solution.

I think that was the way we were turned off to so-called camping, thirty years ago, when we set up our tent in the only spot left in the CG, between two monsters with AC and generators.
We were ignorant of the reality at the time, and thought they had a pretty strange idea for 'camping'. I guess I thought camping was more like rubbing two sticks together, etc. B-)

And how could anyone be ornery out here in the wildness, anyway?
And a good cup of coffee ought to fix that case of ornery (ie: not the instant kind)... B-)
