Description
The Reznor 175800 Sensing-Tube Assembly is designed to serve as a pressure sensor that monitors pressure changes in the heating unit of HVAC systems. This tube is mounted in unit heaters and other equipment and operates by sending the air or gas pressure signals to the pressure switch or control board of the system. In the presence of airflow, the tube enables monitoring to occur to achieve safe ignition and combustion. The high or low pressure system can be turned off to avoid overheating, gas leakage.
