    On the couple of gas stoves I've had (that I can recall) the control
    and adjustment seemed to vary a bit.  None seemed to have been
    designed with adjustment - or ease thereof - in mind.  Good luck.<br>
    <br>
    I believe the 100 ppm is an artifact of an old industrial 
    guideline.  Totally wrong for a residential exposure.  The real
    problem is, obviously, that g as ranges are not commonly vented.<br>
    <br>
    Rick Karg, in Maine, worked up more reasonable (testing) standards
    for residential gas ranges, a couple of decades ago.  I believe his
    work is still avialable on the web, if you search.  A good CO
    detector/monitor would be a good thing to have on hand while you
    experiment, imho. <font color="#000000"> T</font><font
