ensuring exact physical mounting and electrical alignment without the need for bracket modifications

This is a critical safety feature for applications where flow must stop during a power failure

providing a seamless retrofit for technicians servicing failing outdoor units

these orifices provide the reliable sealing and discharge coefficients necessary to prevent overfiring or incomplete combustion in high-efficiency gas furnaces

Unused primary voltage leads must be capped with wire nuts or heat shrink to prevent short circuits against the enclosure or other live components

Lochinvar & A.O. Smith 100077876 Valve 326058-756 ensuring exact physical mounting andThe Lochinvar & A. O. Smith 100077876 Valve is a 3 4" x 3 4" NPT combination control designed for high efficiency commercial and residential water heaters and boilers. This slow open gas valve is engineered to prevent rapid pressure fluctuations, ensuring a smooth, controlled ignition sequence that stabilizes the combustion process and protects the heat exchanger from thermal shock. It is factory configured for Natural Gas (NAT) but includes the
