NAVIEN 30000663B Tankless Water Heaters Air Pressure Switch

The Navien Tankless Water Heaters 30000663B Air Pressure Switch is an essential component that guarantees safe operation and efficiency. This stainless steel switch, which is an essential part of the HVAC system, monitors the air pressure of the unit. It is needed for enough combustion and ventilation for the possibility of protection against certain threats. This works through the changes in the internal air pressure of the water heater. A safety shutdown is in this case initiated if the pressure falls below working limits thus preventing probable difficulties such as overheating or faulty combustion. This ensures the safety of the building residents and the equipment in the building. This device is mainly used in home and commercial applications.
