The PN16502 Quick-seal Compression Fitting is required for kitchen hood and other penetrations requiring a
UL-listed sealing device.
Warning: When tightening the nut on the PN 16502 Compression Fitting, use a MAXIMUM
of ½ turn past hand tight. Wrenching the nut past ½ turn can begin to collapse the
detection tubing.
TUBING SPACING & ROUTING - PRM
The detection tubing is to be run at the top of the plenum, behind the filters from one end of the plenum to the
opposite end to ensure total detection coverage. Ensure that the tubing is routed in such a way as not to
interfere with any moving parts or access openings. Tubing must not be obscured by structural or support
structures, and should be fully exposed to any rising hot gasses from the cooking media, to ensure rapid
detection response. Terminate the tubing within 6” (15.2cm) of the end of the plenum. Refer to page 4-7 for
proper end of line installation. The tubing is never to be routed in the path of hot flue gases from a gas fired
appliance for this can result in a unwanted discharge. Never locate the tubing where the daily removal of the
filters will result in scraping or damaging the tubing surface for this too will result in an unwanted discharge.
Additionally, the detection tubing is to cross over the hood / duct opening in compliance with NFPA – 17A.
When the opening width exceeds the 18” (45.7cm) maximum mounting clip spacing, the tubing is to be
installed along at least three of the four sides of the hood / duct opening. See figure below:

SECURING THE TUBING - PRM
The tubing must be secured at a distance not to exceed 18” with PN16501 Tubing Clip. A Tubing Clip is also
required within one inch of the End of Line Fitting. Since the tubing snaps into the clip, it is recommended
that the clips be installed first, then the tubing. Ensure that the tubing is routed in such a way as not to
interfere with any moving parts or access openings. Tubing must not be obscured by structural or support
structures, and should be fully exposed to any rising hot gasses, to ensure rapid detection response. Never
take up slack by pulling the tubing through a series of clips, this action could damage the tubing and shorten
its useful life.
