Scale is formed mostly on the bottom of the burner cylinder. Gently scrape the
scale off with, for example, a screwdriver. If necessary, also clean the burner cylin-
der walls and thermal radiator. The base mat should be replaced, at the same time
as the burner is cleaned.

To assemble the burner, perform the steps listed above but in reverse order. When
assembling the burner cylinder, ensure that the thermal radiator is locked into
place. To make sure, turn the burner upside down and tap it. This should dislodge
the thermal radiator if it is not locked in place. When installing the burner assembly,
move it around to make it settle snugly in the heat exchanger. Twist the burner into
place and push the retainer spring under the burner.
The fuel needle is in the correct position when the needle is angled towards the
fuel pump. It is recommended that the fastening screws of the burner housing be
coated with heat-resistant grease to prevent jamming.
