Cleaning the burner

Use a brass wire-brush to carefully remove combustion

Clean the jets, injectors and burner rails with a soft
brush and blow out any dust or dirt outside the install-
ation room from the outside to the inside using com-
pressed air.

and rinse it thoroughly with clean water.

Cleaning the injector rail
1.
Check the components of the injector rail for dirt and
damage. You must never remove the burner jets.

Clean the dirty components using a soft brush (leaving
the installation room to do so), and replace any dam-
aged components if required.

Check whether the burner jets are blocked. If a jet is
blocked, carefully remove the blockage without dam-
aging this jet.
