## Description

Combustion Shutoff Device Assembly Replacement Kit for Water Heater FVIR or FTR Fixed Thermal Release, Compatible with Ruud, Richmond, Rheem, GE and Almost Any Gas Tank Water Heater

## Features

- Full Compatibility: Flammable Vapor Ignition Resistant (FVIR) feature is available for Ruud, Richmond, Rheem, GE and is compatible with virtually all gas water heaters. Ensure safe and stable operation of the unit by providing a reliable combustion control solution.
- High Quality Products: Thermal Release Device (TRD) is a product of strict quality control. Thermal Release Device (TRD) is manufactured with high quality materials and advanced technology to ensure product reliability and extend the service life of your water heater, thus saving you money and energy!
- Principle of Operation: The combustion shutoff device is the greatest safety feature of the water heater. When the combustion chamber temperature is too high (>500° F), the glass bulb ruptures and the damper rod pops out, shutting off the gas supply and extinguishing the flame. Effectively prevents danger.
- Safety and Worry-Free: The combustion shut off device dramatically reducing the likelihood of water heater accidents and keeping you worry-free while taking hot showers and many other daily activities, TRD will win you over by protecting your water heater from accidents.
- Please Note: Follow the manufacturer's guidelines and consult a qualified professional before performing any replacement or repair. Replacement of the shut-off combustion component assembly should only be done in the absence of a flammable vapor incident and component failure.
