Fan for Sime Format System 24 central heating Boiler.

Specially designed for extracting hot combustion flue gases from domestic central heating boiler combustion chambers and discharging them via a suitable flue system, these fans are intended for use on the Sime Format System 24 boilers. They have the Sime part number 6225621 and are identified by Ezypart with the reference VF112.

They are powered by 230V 50Hz mains electricity supplied to the Faston tags on the fan motor via insulated cables within the boiler. The power of the motor has been matched with the impellor inside the scroll case to ensure that the fan causes the correct flow rate of flue gases to pass out of the boiler. The motor is attached to a triangular bracket that is mounted onto the steel scroll case via rubber anti-vibration feet. The inlet of the scroll of the fan is a circular hole that coincides with a hole in the top of the combustion chamber flue hood. The scroll case outlet is circular and is designed for the boiler flue connection to be coupled to it.

A flexible resilient seal, capable of withstanding the hot flue gas temperature, is fitted between the fan and the flue outlet to ensure there is no escape of flue gases. During manufacture, all fans are run at their design speeds and the impellors are dynamically balanced in two planes. This ensures smooth, quiet and vibration-free running.
