Reznor rz147670 Limit Control FT100-200

Product Description

The REZNOR rz147670 is a limit control designed for use in REZNOR unit heater systems. A limit control is a safety device that monitors operating temperatures and shuts down the burner when temperatures exceed a set threshold, protecting the heat exchanger and surrounding components from damage. This part is installed by licensed HVAC technicians during routine maintenance or when replacing a failed safety control in a commercial or industrial heating unit.

The rz147670 limit control is intended for use with REZNOR FT100-200 unit heaters. These are typically gas-fired unit heaters found in commercial and industrial settings such as warehouses, garages, and manufacturing facilities. This control maintains safe operating temperatures during normal heating cycles and serves as the primary high-limit safety cutout for the system.
