According to HA HA Budys Here :
New code applies to new construction, or new circuits installed TODAY, not new
appliances. Hook up your new stove exactly the way the old one was connected

Not always. While _most_ old practise is grandfathered, there are exceptions.
Like smoke detector rules. It _certainly_ is here in the case of stoves and
dryers.
