I honestly can't confirm or deny what you are saying isn't true on the newer Lennox units, but the older residential units had it.
This 1994 model AC (see attachment) had it, so I would wager his early 1990's G14 unit did too.
I have an older model number nomenclature pdf (dated 2004) that shows all the electrical codes for Lennox's residential model numbers.
I agree with rundawg, it was on all their units until recently(not sure when they dropped it). it is not on their new stuff, at least not like it used to be(-3P for example).
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."
