Haoguo Combustion Shutoff Device Assembly Kit for FVIR Water Heaters | Compatible with Rheem, Ruud, GE & More

Safer, smarter maintenance for your FVIR water heater

The Haoguo Combustion Shutoff Device Assembly Kit is designed to be the primary safety feature of FVIR water heaters. When the combustion chamber overheats beyond a critical limit, the glass bulb breaks, triggering the damper rod to close the air supply and extinguish the flame. This mechanism helps reduce the risk of fire, gas leakage, or hazardous events, letting you focus on daily routines with more confidence.

Not just a safety valve, this kit offers practical, real-world value. By replacing the activated TRD assembly rather than a full heater, you can extend the unit’s service life and potentially lower replacement costs. The design emphasizes reliability and straightforward maintenance, so hot showers stay comfortable without interruption and you can approach routine service with greater peace of mind.

What this kit does for you

• Supports FVIR type water heaters, compatible with Rheem, Ruud, Richmond, GE, and many gas tank models.
