Noisy Alde 3020

pregan

We have a 2018 T@B 320S and recently were camping at 10,500 ft. The Alde heater made noises when it came on all night long . I have read about modifications to the 3010 model but what about the 3020 ? I would appreciate any input anyone has .
Thanks ,

Where were  you camping at 10,500 feet?

I am not sure that the 3020 automatically switches to accommodate elevation.  Don’t you need to go into the Alde display and select High altitude mode?

You do need to select the high altitude icon that looks like two mountain next to each other.

@pregan;

For the 3020 High Altitude Mode to function you must activate (turn it on) in the correct sequence.

The Propane power source must be OFF, select High Altitude, then select (turn on) Propane as your power source.

Manual Reference

Also the Display will show that you have turned on one of the special features by lighting (it might flash) the "A" symbol.
