摘要： A gas heater for a swimming pool or spa includes a cabinet defining an interior, a combustion chamber enclosure, a heat exchanger positioned within the combustion chamber enclosure, a burner, a combustion blower configured to provide combustible gas to the burner, and electrical components positioned within the cabinet. The cabinet has a plurality of side panels and a top panel covering a top opening to the interior of the cabinet. The combustion chamber enclosure defines a combustion chamber, and is positioned within the interior of the cabinet. The combustion chamber enclosure also includes a burner opening in which the burner is positioned such that the burner is configured to dissipate combustible gas into the combustion chamber. At least one of the electrical components is configured to control the gas heater. The electrical components are accessible through the top opening when the top panel is removed.

摘要： Exemplary embodiments are directed to swimming pool heat exchangers including a housing and one or more tube assemblies disposed within the housing. Each of the tube assemblies includes an elongated titanium tube and at least one fin welded to an outer surface of the elongated titanium tube. The elongated titanium tube and the at least one welded fin allow for corrosion resistance to swimming pool water while simultaneously allowing for improved heat transfer from the heat exchanger to the swimming pool water.

摘要： Exemplary embodiments are directed to a gas switching device including a body and a gas selector mechanism. The body includes an inlet and an outlet. The gas selector mechanism includes a first orifice in fluid communication with the inlet and a second orifice in fluid communication with the inlet. The gas selector mechanism includes a valve arm and a selector element. The selector element is configured to actuate the valve arm between a closed position and an open position. In the closed position, the selector element actuates the valve arm to close the second orifice for passage of a first type of gas through the first orifice. In the open position, the selector element actuates the valve arm to open the second orifice for passage of a second type of gas through both the first orifice and the second orifice.
