Project: HVAC
Project Address: 316 Walnut St.
During review of the re-submitted plans for the above noted project, it was found that the following
information, clarifications or changes are needed. Please provide written responses as to where the
changes can be found on the plans, and submit revised plans/documents to a Permit Coordinator.
1.Indicate on the plans the size and location of the kitchen hood exhaust ductwork. Bear in mind
that the stairwell walls are a vertical exit enclosure and cannot be penetrated by the ductwork per
IBC section 1020.1.2
2.Provide cut sheets for the firestop products proposed for all penetrations requiring a firestopping
system.
3.Units 202 and 302 both need to have min. 50 cfm fans in the separate master toilet rooms.
4.How are the rated horizontal assemblies to be protected at the fan and duct penetrations? If the
fans will have radiant ceiling dampers provide the product data. If the fans enclosures will have
gypsum boxes built around them, provide a construction detail.
5.For all membrane and through penetrations provide the listed, tested firestopping product data.
6.The shafts that the vents are proposed to be enclosed in will need to be built as shafts per
section 707 if the floor/ceiling assembly is not complete and firestopping provided at each
penetration.
7.Indicate the piping size and material of the hydronic piping from the water heater to the heating
units.
8.Indicate the hydronic piping insulation.
