    Hello,


    I've had to replace the ITT Generator once a year for the past three years, else
    the pilot light won't stay lit.

    New Buck, Model 19GL Propane Stove.

    ITT Generator Part Model: G251F36S
    What's the difference between a ITT Generator and a Thermopile?

    Picture of old ITT Generator (ITT is on the left)
    The condition is typical of ones I've replaced over the last few years.

    Is one year the life of an ITT Generator?
    Any hints or suggestions on what to try next?


    Thanks,

    Woody

    Can't even find a Buck Model 19GL listed on the Buck Stove site.
    What is it? Vent free?

    Thanks Bob.

    Yes, Vent Free. More research reveals that 19GL is the model of the internals.

    There is no external model on this unit.

    It could be a model 42 or model 34 (both of which can have the 19GL innards) per these pdfs.

    Looks like ITT uses a specific Thermopile for their gas valve.
    It looks a LOT less substantial than most. LP seems to eat up
    the components in the firebox more rapidly than NG does, so
    I'd say if you hafta replace it every year, there's nothing you can
    do about it, unless you change the gas valve to a SIT unit.
    That one uses a standard T-pile & it may last longer.
    I've got an LP insert with the larger version that I've had since 03
    & only changed the T-P once...
