CAUTION: The burner box cover can be hot. Wear
gloves to avoid burns.
- Remove the burner box cover by removing the screw.
- Look at the gas flame [1] (See Art01605).

- a darker blue color on the inside of the flame and
a lighter blue color on the outside of the flame.
- a constant shape without flickering.
- Contact your dealer or Norcold authorized service
center if the flame is:
