What it is
The Potterton 5139863 insulation, sweeping door, is a boiler door insulation component for Potterton Commercial NXR4I series gas boilers. It sits within the appliance door assembly, where it limits heat loss through the door and protects surrounding components from radiated heat. The part is supplied to the manufacturer's specification for the NXR4I range.
