chamber.

14. Bring boiler to maximum temperature. (Set
Logamatic control, if present, to manual setting).
Remove gas burner tray after the boiler has dried
out.
15. A thorough brushing of the heating surfaces is
recommended. This requires a disassembly and
reassembly as previously discussed.
16. Clean burner chamber and insulation board in the
bottom of the chamber.

1. Remove burner tray cover plate screws from the
burner tray box.
2. Remove ignition cable (Fig. 38, Item. 4) from pilot
burner assembly (Fig. 38, Item. 1).
3. Loosen the pilot gas line (Fig. 38, Item. 3) on the
pilot burner (Fig. 38, Item. 1).

5. Dip burner tubes into water with dishwashing
cleaning agent and brush off. Ensure that insulation
does not get wet.
6. Rinse the burner rods with a stream of water: when
doing so, hold the gas burner in such a way that the
water penetrates into all burner perforations and
runs out again through the Venturi tubes.
7. Remove the rest of the water by shaking the burner
tubes.
8. When necessary, clean burner box housing and air
intake hose.
9. Check the burner perforations for free passages;
remove any water from the perforations. If any
perforations are damaged, the burner tray must be
replaced.
We reserve the right to make any changes due to technical modifications!
