<p>PURPOSE: To provide a connection strip which can be manufactured inexpensively and easily through casting or molding as an independent intermediary body coupling the inlet/outlet on the boiler body side of a dual-purpose boiler, the radiating side of heating, the hot water output side, and a pipeline on the water supply side. CONSTITUTION: The connection strip R comprises four modules A, B, C, D made of molded hard plastic and assembled side-by-side by being mutually juxtaposed with tie bars 16 passing through them, the modules being respectively associated with outgoing heating water, outgoing domestic hot water, incoming cold water, and returned heating water. Short-circuits 26, 31, 38, 46 are formed between the inlet and outlet of heating piping and pressurized water is fed to a radiating circuit for heating so that leak tests of the circuit can be performed before a boiler is fixed.</p> |
