    Default Water Heater in Garage

    What is the code pertaining to water heater elevation in a garage, and are newer water heaters with closed systems exempt from this requirement?

    We have had several recent threads on that, and, yes, ignition sources are required to be raised 18" above the garage floor, and, for your last part of the question - yes, those are exempt from having to be raised that 18" (although it is not a bad idea to raise them anyway).

    This is one of them: http://www.inspectionnews.net/home_i...r-heaters.html

    You may need to protect the water heater from damage (gas water heater) or raise it six feet.

    Wayne,

    ANY appliance in a garage needs to be protected or raised.

    He didn't ask about any appliance. He was asking the particulars on a water heater.

    Now you guys are confusing me. Unforyunately, it doesn't take much. Is a gas heater required to be raised or is it just a good idea?

    I understand, but you stated "water heater from damage (gas water heater)" as though "(gas water heater)" only had to be protected or raised and an electric water heater did not need to be raised or protected.

    So instead of just addressing "electric water heaters too" I addressed "all appliances" - because that is correct.

    Yes, the gas water heater must be raised, unless it is the newer type which is exempt from that requirement, as do all ignition sources.

    My comments below:

    However, if it is a water heater that is flammable vapor ignition
    resistant then it is allowed to be installed on the garage floor like Jerry stated HOWEVER you may need to raise it anyway if it is subject to vehicle impact damage except where protected by an approved means.


    SECTION 305.3 (IFGC)

    305.3 Elevation of ignition source.
    Equipment and appliances
    having an ignition source shall be elevated such that the source
    of ignition is not less than 18 inches (457 mm) above the floor
    in hazardous locations and public garages, private garages,
    repair garages, motor fuel-dispensing facilities and parking
    garages. For the purpose of this section, rooms or spaces that
    are not part of the living space of a dwelling unit and that communicate
    directly with a private garage through openings shall
    be considered to be part of the private garage.
    Exception:


    Elevation of the ignition source is not required
    for appliances that are listed as flammable vapor ignition
    resistant.


    SECTION 303 (IFGC)
    APPLIANCE LOCATION
    303.4 Protection from vehicle impact damage.
    Appliances
    shall not be installed in a location subject to vehicle impact
    damage except where protected by an approved means.

    So to sum it up......
    A water heater may be installed on the garage floor IF it is listed as flammable vapor ignition resistant and it is protected from automobile impact. If it is not protected then it must be raised 6 feet tp protect the water heater from automobile impact.



    305.5 Private garages. Appliances located in private garages
    shall be installed with a minimum clearance of 6 feet (1829
    mm) above the floor.
    Exception:


    The requirements of this section shall not apply
    where the appliances are protected from motor vehicle
    impact and installed in accordance with Section 305.3.

    Personally I would check with the local plumbing inspector. I have been in towns that still require the FVIR type water heaters to be raised. Their reasoning behind this is a home owner or handyman may open the front access to service the heaters FVIR screen and not properly reseal the chamber with a new gasket.
