us stove 5500m issue

[skibladerj]

As my second year with the stove starts i have noticed a odd condition.
When the stove runs low(setting1 or 2) the stove runs flawlessly. But once i set it to a 3 or higher it indicates a draft issue. At first i thought that it was over heating and cutting back but tgars not the case. So any ideas would be great.

Is it clean first?

Is there a "draft plate' or a level for changing air flow?

Yes its clean... no on the draft plate its all controlled by the exhaust fan.

Its just strange to me that on a setting on 1 or 2 it runs like a top no issues at all. In fact i can get a week between cleanings which is alot for this model.

Well I'd imagine someone who knows that stove will be along to help ya soon.
