PLUS AND SMART SYSTEM KIT

Plus System Kit: the complete solution to all installation complexities. The Famar heating fireplace meets the long- standing need to manage a system with a solid fuel heat generator (open circuit) and interface it with another generator (closed circuit). This need is satisfied by the Famar heating fireplace which, upon request, can be equipped with the completely pre- mounted Plus System Kit, assembled and accessorized with all the necessary components, in order to avoid significant energy expenditure and guarantee savings in labor and materials. In fact, Famar heating fireplaces are meticulously detailed: connections, copper piping, and a stainless steel expansion tank, offering safety that complies with current regulations. In this way, the plumber has a series of connections available at the bottom of the heating fireplace shell—on either the right or left side as preferred—to be linked to the main manifolds.

THE ADVANTAGE OF A PRE-ASSEMBLED KIT

The Plus System Kit includes, within a compact and pre- assembled space, the stainless steel expansion tank and the connections between two heat generators. This setup resolves the issues normally found in open-circuit systems. In this way, it is no longer necessary to install an open expansion tank— along with its relative safety and loading pipes—on the ceiling of the home where the system is located.

1 – Stainless steel expansion tank 2 – Automatic air vent valve 3 – High-efficiency secondary circuit circulator 4 – System flow ø 1’’ 5 – System return ø 1’’ 6 – Heating fireplace drain cock ø 1/2’’ 7 – Certified thermal discharge valve outlet ø 3/4’’ with 95° temperature (safety) 8 – Domestic hot water outlet ø 1/2’’ 9 – Main water inlet with 6 bar safety valve ø 1/2’’ 10 – Primary circuit circulator 11 – Plate heat exchanger with counter-current heat exchange, appropriately sized according to the power of the heating fireplace 12 – Water hammer shock absorber and 1-liter expansion tank (prevents the mechanical float from opening due to instantaneous pressure increases in the mains water supply circuit)

COMPONENTS AND PRE-ASSEMBLY DIAGRAM OF THE SMART SYSTEM KIT ON THE HEATING FIREPLACE

The Smart System Kit offers a versatile interface for control between an open vessel and a closed vessel, equipped with the same functionalities as the Plus System Kit. Its hydraulic simplification, characterized by the absence of certain components (as indicated in the diagram), makes it an effective and intuitive solution for specific needs. 1 – Stainless steel expansion tank 2 – Automatic air vent valve 3 – High-efficiency secondary circuit circulator 4 – System flow ø 1’’ 5 – System return ø 1’’ 6 – High-efficiency primary circuit circulator 7 – Plate heat exchanger with counter-current heat exchange, appropriately sized according to the power of the heating fireplace 8 – Heating fireplace drain cock ø 1/2’’
