Probably can't find anything because you're using the wrong terms.
As per D45 - What's a weather head?

It's the cap on top of the conduit that incoming power lines attach to if you have overhead service from the power company.

Weather head is where the overhead power comes in and drops to the meter.

I'd stay at least 36" away from any incoming power cables and the weather head. I think that's NEC requirement.
"Overhead service conductors must maintain a clearance of 3 feet from doors, porches, balconies, ladders, stairs, fire escapes, windows that open, or similar locations [230.9]"
Look here for explanation of NEC requirements regarding weather heads and service entrance conductor clearances.: http://ecmweb.com/code-basics/article-230-services-part-2

Ah. The electrical mast with weather head on top.
As mentioned - that'll be in electrical code not HVAC. Not sure if NEC covers this or if it's justidiction of the PoCo. Although looks like there's language there as posted above.

We'll see if GJ Sparky's will chime in with specific details.
As for convenience of service, etc . . . . I'd sure avoid it. Other options to put heater in different location ?? Any location that you could install heater with a horizontal exhaust flue ??
Also, if heater flue above the roof is so tall it needs guywires, you sure don't want that close to your electrical weather head.
