    So after (I assume) you reset the rollout...then what happened? Do you have any other info as to readings or anything?
    A tripped rollout ain't a good sign.
    How old is this thing? This rollout, its over the burners or in the collector box, or...?

    after I reset the limit, I turned the heater on and it did not roll out, I tested the unit about 10 times, the limit is on the collector box

    Sounds like the chimney backdrafted, if this is an old gravity draft model
    Probably would be prudent to check that it's not partially blocked or something
    Sometimes that kind of thing just happens, if it's excessively windy.

    After changing the gas valve, did you check to outlet gas pressure?
