HEIGHT MODE

Unfortunately this heater does not have a height mode., The manufacturer indicates that it should work well up to 1800m, but it may not be enough for you.
All is not lost, after doing several tests, having pump 22ml can configure as if it were a 28ml pump, In my tests the combustion chamber was around 110/120º at the minimum and at the maximum around 170º, enough to work well at any height.. According to circumstances, mounting, etc. those values ​​could vary.
If with that trick you had carbon problems, the solution would be to change screen + switchboard for the version “universal” Yes, it allows you to configure parameters, and configure it to height.
