When the TRD trips, the glass bulb breaks which allows a spring loaded metal damper rod (housed in the water heater frame underneath the burner assembly) to spring up, thereby cutting off the air supply to the chamber which, in turn, extinguishes the burner flame.
What does TRD stand for water heater?
Rheem TRD/ thermal device. Resource: Verify activated TRD pdf. Solution 2: Call Rheem or manufacturer: Check warranty, part availability, etc. Rheem, Richmond, Ruud, GE water heater: Gather information from label on side of tank, then contact Rheem and ask for glass vial, and other affected parts.
How does a FVIR work?
FVIR water heaters are designed to keep burning vapors inside the combustion chamber of the water heater until they burn out. A sensor inside the water heater will detect if it has ignited a flammable vapor from outside of the water heater and shut off the flow of gas to the burner and pilot light.
What is the safety device on a hot water heater?
Tank-style water heaters are outfitted with an important safety device called the Temperature & Pressure Relief Valve (T&P). It’s role is to release pressure within the tank when it builds to an unsafe level.
What is flammable vapor ignition resistant?
In case of a flammable vapor ignition resistant water heater, its technology prevents flashback fires from breaking out by trapping and burning the hazardous gas vapors inside its body instead of in the room.
What does a thermal switch do on a water heater?
A thermal switch is installed in newer gas water heaters as a safety device. Blocked vents at the top and bottom of the water heater can cause excessive heat buildup inside the chamber and trip the thermal switch, shutting off the gas supply to the burner assembly.
How do you fix flammable vapor lockout?
Quote from the video:
Quote from Youtube video: Disconnect. The power to it wait for 10 seconds. And then plug it back in and then. If you just wait for like five seconds after that. Press both of the arrows together.
What is a thermal release device?
Thermal Release Device- A small glass bubble or vial that is designed to cut off the fresh air entering the combustion chamber as during an extreme overheat situation.
Do FVIR water heaters need to be elevated?
No, water heaters do not have to be elevated. For instance, you can have your gas water heaters sit on the floor if it’s flammable vapor ignition-resistant (FVIR). The same applies to all the electric water heaters; they too can be installed directly on the floor.
Can a water heater sit directly on the floor?
According to the Uniform Plumbing Code, a natural gas tank water heater should be installed at least 18 inches from the ground. It’s also important to note that this measurement doesn’t necessarily start at the bottom of the unit.
Are electric water heaters FVIR?
All water heaters now produced in North America are Flammable Vapor Ignition-Resistant (FVIR) types. The ANSI Standard was introduced in July 2003. Existing water heaters that did not meet the standard do not have to be replaced, but all new heaters do have this feature.
What does FVIR certified mean?
Flammable Vapor Ignition Resistant
An Innovation in Fire Safety
Residential water heaters manufactured after 2003 are “F.V.I.R.” (Flammable Vapor Ignition Resistant) compliant. For the most part, this means that the combustion chamber is now sealed.
