Lol. That’s too funny. Everyone thinks fire sprinkler can just magically move.

Just a question. If the duct is to close to the fire main why wouldn’t the duct 
have to move? Isn’t life safety more important than climate comfort?

I am unaware of any language that would support the fire inspector’s position.

No seismic. No insulation.

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.
