And if your intermediate the next column in that table says you still need to 
be 12” away.

Why not use intermediate temp heads everywhere? Then diffuser proximity won't 
matter.

What Steve said.

 

Generally, my experience has been that if they have a heat pump, max outlet 
temperature will be less than 100 degrees. But if they have a furnace, there is 
a good chance it will be higher. Mechanical designer/contractor should be able 
to answer the question.
