De Dietrich 83885681, isolamento del cassetto bruciatore, 5 sezioni

This De Dietrich 83885681 burner drawer insulation set comprises five sections. The manufacturer codes are 83885681 and 336.778.013; the catalogue article is 336.778.013. Parts of this type are insulating segments that line the burner drawer assembly. They seal the combustion chamber and retain heat inside it, preventing energy loss and protecting surrounding components from excessive temperature. Such insulation is selected exclusively by the appliance model and the exact position in the assembly, not by a generic technical rating. Combustion chamber insulation degrades over time due to repeated thermal cycling. When replacing, the geometry of the new sections must match the original exactly to avoid gaps that could create localised hot spots. These five sections are intended to be fitted together as a complete set for the burner drawer. No dimensional or compatibility data is given for this specific article. Always verify that the part corresponds to the appliance model and the correct location in the burner drawer. Using a mismatched or degraded insulation piece can impair burner performance and shorten the life of adjacent components.
