My burner seems to be plugged. flame is only coming out of a few of the holes. how can I clear the burner?

You can take the burner apart.  Here is how:

• Flip the stove upside down.

• You should see a nut fastening the burner to a metal bar across the stove body (wind guard).  Unscrew the nut such that you can take the burner off the stove wind guard.

• Use a wrench to unscrew the bolt in the middle of the burner.  Once it is out, the two pieces of the burners should fall apart.

• Now you can clean out all holes.  Please also check if there is any blockage between the burner orifice inlet and the head.
