© MHS Boilers Ltd Appliance Type. There are three build types within the Streamline FS range. Please ensure you have the correct unit for the application and where required located correctly within the cascade prior to beginning the installation. Standalone Units. (150 FS Product Code 96.30000-7134) (225 FS Product Code 96.30000-7135) The Standalone Unit is supplied with an integral low loss header. This unit does not require the installation of a second low loss header remote from the appliance.
© MHS Boilers Ltd Cascade Manager Units (150 FS Product Code 96.30000-7136) (225 FS Product Code 96.30000-7137) The Cascade Manager Unit is supplied without an integral low loss header. A suitably sized low loss header must be installed within the system. The system’s (Secondary) circulating pumps (Heating / HWS) are to be connected (hydraulically) to the external low loss header and not to the appliances flow and return connections.
© MHS Boilers Ltd Cascade Slave Units. (150 FS Product Code 96.30000-7138) (225 FS Product Code 96.30000-7139) The Cascade Slave Unit is supplied without an integral low loss header and should only installed where a Cascade Master is also installed A suitably sized low loss header must be installed within the system. The system’s (Secondary) circulating pumps (Heating / HWS) are to be connected (hydraulically) to the external low loss header and not to the appliances flow and return connections.

© MHS Boilers Ltd Pressure (Safety) Relief Valve In accordance with BS 6644: 2005, the installer shall install as suitably sized Pressure (Safety) Relief Valve. The location of this valve is important with respect to the applied pressure of the boiler circulation pump, it is therefore recommended to locate the Pressure (Safety) Relief Valve on the flow pipe immediately adjacent to the boiler; furthermore, there must not be any means of isolation between the boiler and the Pressure (Safety) Relief Valve.
