How Do You Test A Fv Sensor?

sensor from it’s bracket on the base ring of the water heater and disconnect both wires to the sensor.

Service Note: Unless the ohm meter used has an auto-range feature the resistance should be checked twice.

How many ohms should a flammable vapor sensor be?

The function specs says it is a one-shot sensor, hence once it tripped, it may have to be replaced. But you can measure whether it is still good. After it cooled down, it should read between 7k and 25k Ohm in the absence of vapors.

How does a FV sensor work?

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.

Can you bypass vapor sensor?

What is FVIR certified?

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.

Are all new 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.

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.
