Clean the generator after use.
For this purpose, it should be dismantled.
Pull out the pipe smoke 3 .
Then take off the mounting base 5.
After a few hours of operation - the inside of the combustion process remains very little ash. With one full filling woodchips, we have approx two tablespoons of ash.
After working you can clean the generator easy. The best and cheapest is caustic soda sodium hydroxide (NaOH)
It is used to clean the drains in home. You can also use the grill cleaner.
Please, remember to rinse with clean water later.
