Cleaning the gas burner

! Remove the gas burner (see "Removing the gas
burner", page 36) for cleaning.
! Release the ignition cable plug-in connector on the
intermittent ignition and remove the ignition unit.
! Release both screws on the pilot burner and carefully
remove it.
! Initially flush the burner rods (Fig. 21, Item 1) with a
water hose from above, then spray the slots from the
front.
PLEASE NOTE
Ensure that the thermal insulation on the
burner shield (Fig. 22, Item 1) stays dry.
! Position the gas burner vertically onto the burner
rods (Fig. 21, Item 1).
! Spray the burner rods (Fig. 21, Item 1) internally with
water and wait, until all water has been expelled from
the burner rod slots.
! Invert the gas burner and position with the burner rod
aperture pointing down to allow water to drain off
(Fig. 22).
! Position the gas burner with slots pointing down to
enable all residual water to drain off.
! Check that the burner rod slots are unobstructed.
Remove water film and residual contamination from
the slots. Replace the burner if the slots are
damaged.
We reserve the right to make any changes due to technical modifications.
