The answer is YES. It only takes a little cleaning. If you would like to use the pellet function several consecutive days, it is possible to scrape slags and ash out from the brazier along the way. We always recommend cleaning the stove when it is cold, but cleaning of the brazier may be done when the stove is running. In this movie we show how (minute 8:00-8:25). The interval for cleaning is greatly influenced by the pellet quality. Therefore, it is important that you only use approved pellets, as some pellet types gives more slags and ash than other.
However, we recommend regular use of firewood, as this cleans the combustion chamber and optimises combustion.
We have learned that most customer with a good chimney can burn for 50 hours at heat level 1 before cleaning is necessary.
