This Lochinvar Venturi Coupling is a specialized component designed for use in various Lochinvar heating systems. It functions as an integral part of the system's gas delivery mechanism, ensuring optimal combustion by regulating the mix of gas and air. The coupling is made from high-quality, durable materials that can withstand the rigors of continuous operation. Its design features a narrow section, or 'throat', which increases the speed of the gas-air mixture passing through it, thereby enhancing combustion efficiency. This Venturi Coupling is compatible with specific models of Lochinvar heaters and boilers, and it should be installed by a qualified professional to ensure safe and effective operation.
