Description
The Reznor RZ112752 Manual Reset Blocked Vent Switch is built for vent safety monitoring in compatible gas heating equipment, featuring a 225F activation rating for detecting elevated exhaust temperatures caused by restricted airflow conditions. The manual reset mechanism requires technician reset after activation, ensuring inspection of vent pathways before restarting operation. Installed in flue and vent sections of furnaces and heating units, it monitors exhaust movement and temperature rise within the system. This switch supports vent condition monitoring, overheating indication, and controlled operational response across gas-fired heating assemblies in HVAC systems.
