Could it be related to seismic movement of unrestrained ductwork against the FP 
pipe?

When you say ductwork, is that ½” between pipe and insulation or actual sheet 
metal?

Subject: [EXTERNAL] Pipe adjacent to duct

We have a project where the fire inspector is stating that the fire sprinkler 
main is too close to ductwork.  There is a 6” main that is about 1/2” from the 
ductwork.

Of course, the inspectors response is “it’s in the code book” when asking for a 
reference that mandates clearance to hvac ductwork.

Has anyone run into something similar?

Note: this is not a high temp duct that would cause for enough heat to convert 
the sprinkler water to steam. This is just your standard, run of the mill, HVAC 
system.
