Please provide a recommended product and installation detail for a penetration thru a 1 hour rated wood floor/ceiling assembly for a 3/4" electrical conduit and a single HVAC line set (total line set penetration is 1 1/4" the conduit must be separated from the line set by 1/2" so total minimum penetration is 1 3/4"
Correction total penetration is 2 1/2" dia
Hello,
Please see if F-C-8014 meets your application needs. If it does not then you will need to go ahead with submitting a new engineering judgment to our firestop team.
Please see details below for submitting an engineering judgment.
We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.
Hilti Firestop Selector App – Google Play Store

If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.
_________________________
Because of the numerous field
conditions encountered, it is not always possible to identify a firestop system
that has been tested / classified by a nationally recognized independent
testing laboratory (such as Underwriters Laboratories, Underwriters Laboratories
of Canada, Factory Mutual, Intertek/Omega Point, etc.). In such a case,
an Engineering Judgment (“EJ”) or Firestop Custom Detail (“FCD”) may be
appropriate. An EJ/FCD represents a firestop solution that would be
expected to pass the stated ratings and requirements if tested.
All Hilti EJ’s/FCD’s are
designed in accordance with the International Firestop Council (“IFC”)
guidelines. These EJ’s/FCD’s are designed by our experienced degreed fire
protection technicians using, as the basis for our opinion:
• relevant 3rd-party testing in
accordance with ASTM E-84, ASTM E-119, ASTM E-136, ASTM E-814, ASTM E-1966,
ASTM E-2307, CAN/ULC-S115-11, UL 263, UL 723, UL 1479, UL 2079, or ASTM E-2837
• wide-ranging related internal testing of our firestop products, and •
extensive knowledge and experience of the performance characteristics of Hilti
firestop products, and firestopping technology generally.
Pursuant to IFC guidelines,
each EJ/FCD is intended for one specific jobsite, since even slight variances
from one application to the next can affect system performance.
Best regards,
Kevin Riechers
