Thanks for the advice.

I'd like to use the manufacturer's (OS) instructions for the break-in procedure. Those instructions have us start with 1 minute at 4-cycle, then alternate between 10 seconds at 2-cycle and 10 seconds at 4-cycle for the balance of the tank. So, as you advise, we're not really breaking it in at "COLD" 4-cycle temperatures but rather alternating between hot and cool temperatures.

My problem is that I don't know how to recognize 4-cycle operation.

Maybe I'll learn to recognize it tomorrow!!
