Review NAVIEN Air Pressure Sensor

The Navien APS-02-D Air Pressure Sensor is an essential component in the combustion system of Navien's condensing tankless water heaters. This sensor is designed to monitor and maintain the optimal air pressure required for efficient and safe operation of the water heater.

The APS-02-D sensor is a compact, durable device, measuring approximately 3.5 inches long and 1.5 inches in diameter. It is made of high-quality materials, including a stainless steel housing, to ensure long-lasting performance and resistance to corrosion. The sensor is also equipped with a protective seal to prevent water intrusion and potential damage.

The Navien APS-02-D Air Pressure Sensor features a diaphragm design that accurately measures and responds to changes in air pressure. It is calibrated to detect air pressure variations within the range of 0 to 10 psi, with a recommended operating pressure of 2.5 psi. The sensor sends this information to the water heater control module, which adjusts the combustion process accordingly to maintain the optimal operating conditions.

Installation of the Navien APS-02-D Air Pressure Sensor is straightforward, with clear instructions provided in the user manual. The sensor is connected to the water heater using a standard 1/4 inch NPT threaded fitting, and the wiring is connected using color-coded terminals for easy identification. The sensor is typically installed near the top of the water heater, with the air pressure line connected to the intake side of the combustion chamber.

The Navien APS-02-D Air Pressure Sensor is an essential accessory for Navien condensing tankless water heaters, ensuring optimal performance and safety. Its durable construction, accurate pressure measurement, and easy installation make it a reliable and cost-effective solution for maintaining the optimal operating conditions of your water heater.

The Navien APS-02-D air pressure sensor is a crucial component for ensuring optimal performance and efficiency in Navien condensing tankless water heaters. Here are some pros and cons of purchasing this sensor.
