ACV Bruciatore isolato 51700106

ACV Insulated burner 51700106 is a thermal insulation panel for the front door of ACV Prestige boilers. It measures 236x146x30 mm and is designed to fit ACV Prestige 24 MK2, Prestige 32 MK2, and Prestige 50 MK2 models. This insulation retains heat within the combustion chamber, preventing heat loss and protecting the boiler body from overheating. It is a genuine ACV part, listed under SKU 51700106 and article number 129.790.004.

Parts of this type are selected by the exact boiler model and the intended mounting position. Before ordering, confirm the dimensions and fit against the original component, as geometry must match precisely to ensure proper installation. The insulation is typically placed on the front door, and replacement requires removing the old panel and fitting the new one in the same orientation.

Over time, heat cycling causes the insulation material to degrade, leading to reduced thermal efficiency and potential hot spots that can damage surrounding parts. Signs of failure include increased heat loss from the boiler front, discoloration or warping of the door, or visible cracks or crumbling of the insulation material. If these symptoms occur, inspect the insulation and replace it with a piece of identical geometry.
