What it is
The Sime fan assembly, part number 5183602, is the combustion fan unit used on Sime Super FOUR gas boilers. It draws flue gases through the heat exchanger and discharges them to atmosphere, and it also provides the air supply for combustion. The assembly is supplied under the Sime ES30-108 DR fan reference.
