8 Inspection and maintenance Cleaning the burner Use a brass wire-brush to carefully remove combustion residues from the burner without damaging the burner. 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.
Inspection and maintenance 8 Removing the down-draught diverter Removing the heat exchanger Remove the cables from the flue gas sensor. Remove two screws each from the fixing plates on the heat exchanger. Remove two screws each for securing the down- draught diverter on the back panel of the product.
