Lochinvar & A.O. Smith 100166241 Pressure Switch R-410A the UVC intensity degrades overThe Lochinvar and A. O. Smith 100166241 Pressure Switch is a critical safety component designed for precise combustion air monitoring in high efficiency water heaters and boilers. This SPDT (Single Pole Double Throw) switch is factory calibrated to a . 21" WC (water column) set point, ensuring the inducer fan generates sufficient static pressure before allowing the ignition sequence to proceed. Engineered as a direct OEM replacement part, it replaces
