FLAMMABLE VAPORS ARE A SERIOUS SAFETY HAZARD! Vapors from flammable productssuch as gasoline, kerosene, paint thinner, and solvents can be ignited accidentally by the pilot light of a propane appliance.Sometimes the vapors may follow air currents in the building to higher levels.
What does a flammable vapor sensor do?
What is a Flammable Vapor (FV) Sensor? FV Sensors are safety devices on select models of water heaters, which cause a soft lockout (a.k.a. the unit shuts down) when flammable vapors are detected near the unit, to prevent the possibility of their ignition.
What is flammable vapor ignition resistant?
What does FVIR mean? Flammable Vapor Ignition Resistant (FVIR) water heaters incorporate design features that make them resistant to igniting flammable vapors such as gasoline, cleaning solvents, and paint thinner outside of the water heater.
What can ignite flammable Vapours?
Liquids (such as petrol and other fuels) and solvents in industrial products (such as paint, ink, adhesives and cleaning fluids) give off flammable vapour which, when mixed with air, can ignite or explode. The ease by which liquids give off flammable vapours is linked to a simple physical test called Flashpoint (ie.
What fumes are flammable?
Flammable: A liquid with a flash point under 100°F is considered flammable. Examples: gasoline, acetone, toluene, diethyl ether, alcohols. Hazard: May produce ignitable vapors at normal ambient temperatures.
What is a vapor sensor?
The sensor is designed to detect the presence of a specific concentration of gasoline vapors.The proprietary conductive polymer sensing film expands in the presence of flammable vapors significantly changing sensor resistance.
Are all water heaters flammable vapor ignition resistant?
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.
Are all gas water heaters FVIR?
Residential water heaters manufactured after 2003 are F.V.I.R. (Flammable Vapor Ignition Resistant) compliant.10.1a-2002 standard will apply to virtually all gas fired residential water heaters with BTU ratings of 75,000 and below.
Are Bradford White water heaters FVIR?
The Defender Safety System® is the name of Bradford White’s exclusive flammable vapor ignition resistant (FVIR) system. It is a proven feature in many of our residential gas water heaters that resists the ignition of flammable vapors outside of the water heater.
What are flammable materials?
Flammable materials are the ones that are ignited or flame immediately when contacting with fire or high temperature in the air and continue to burn or slightly flame when leaving fire, such as plywood, fiberboard, wood and foil.
What are some highly flammable substances?
Examples Of Highly Flammable Chemicals Used In The Lab
- Acetone.
- Benzene.
- Methanol.
- Cyclohexane.
- Ethanol.
- Pentane.
What causes flammable liquid fires?
For a flammable or combustible liquid fire to start, a mixture of vapour and air must be ignited. There are many possible ignition sources: Sparks from electrical tools and equipment.Sparks caused by static electricity from rotating belts, mixing operations or improper transfer of flammable or hot combustible liquids.
Is diesel vapor flammable?
Diesel vapors can ignite and explode when mixed with air.The lower explosive limit is less than 1%, and the upper explosive limit is about 10%. That means that diesel fuel vapors from a storage tank can explode with as little as 1% of the air being diesel fuel vapors.
Is gas vapor flammable?
Naturally, gasoline vapor comes from gasoline. Vapor is a substance produced by some liquids; part of the liquid diffuses into the air, retains some of the properties of the original liquid, and becomes flammable.Interestingly, only the vapor of a flammable liquid like burns, not the liquid itself.
Will a cigarette ignite gasoline vapor?
It is possible to ignite a pool of gasoline using only a cigarette. A cigarette has the potential to light a pool of gasoline but just doesn’t have enough sustained heat. Gas ignites between 500 °F and 540 °F, the cigarette at its hottest was between 450 °F and 500 °F but only when it was actually being smoked.
Can you bypass a flammable vapor sensor on a water heater?
You cannot easily bypass this sensor.If your gas water heater suddenly stops working, it is very likely that this sensor is the cause.
Are flammable vapor sensors universal?
Answer: Hello, if all the spec. Are the same it will work.
Why does my Rheem water heater keep shutting off?
The power vent water heater keeps shutting off
If your power vent water heater keeps shutting off, the thermocouple could be damaged, dirty or bent. Inspect the thermocouple. If it is damaged, replace it. If dirty, let it down for cooling and then clean.
How do you reset the vapor sensor on a Rheem water heater?
Turn the water heater’s gas valve switch to the “OFF” position, wait for a few seconds and then flip the switch to the “ON” position to reset the system.
What does lockout mean on hot water heater?
The lights on the front show the vacation light on, and A and B, which the manual says is the lockout phase. It gives 4 options: 1) Gas supply is off or too low to operate. 2) Hot surface ignitor not positioned correctly. 3) Low voltage to the water heater.
Do FVIR water heaters need to be elevated?
jolson8: Most gas water heaters in the 30-50 gallon range sold/manufactured in America since 2003 are FVIR (flammable Vapor Ignition Resistant) By 2005, all sold are FVIR. If a water heater is FVIR, it does not have to be elevated when installed in the garage.
