The smoke vent curb flange comes with two (2) types of mounting holes to
accommodate the following fastening methods:
a.
Mark the predrilled 5/8” diameter holes from the mounting flange through to
the roof deck or a concrete curb. Drill roof deck or concrete curb for installation
of anchors or other fasteners (provided by others). Bolt or otherwise fasten roof
hatch curb flange to roof deck using 3/8” or 1/2” bolts with washers.
b.
Mark the predrilled 3/16” diameter holes from the mounting flange through to
the roof deck, typically into a built-up wood frame curb. Fasten roof hatch curb
flange to framing using roofing nails and/or screws, recommended size #10 by 1-
1/4” long.
3.
Install roofing material up to and around the roof curb and under the counterflashing
using appropriate roofing material and locally accepted processes. Ensure all joints are
full sealed to provide a weather tight seal.
4.
Finally, to check operation, open the smoke vent doors by pulling the exterior manual
pull handle. Closing the doors may require two people to ensure proper latch
engagement.
OPERATION
•
Vents are designed and built for years of dependable service. Smoke vents do not
require field painting. If field painted, all component parts must be masked, especially
moving parts and all labels. Field painted component parts will void the warranty.
•
Latch: Positive hold rotary latches are designed to hold the covers closed.
•
Gas Spring/Damper: Provides force to automatically open covers.
•
Hold Open Arm: Automatic hold open arm engages to keep doors locked open when
released. Pull the red vinyl grip handle forward to disengage while safely closing the
door(s).
•
Link: Fusible melt out links are replaceable (SV-KIT-LINK-165, SV-KIT-LINK-280, etc.)
Smoke vents are designed to open manually via pull handles located on the exterior and
interior of the smoke vent. The internal pull cable can be extended and rigged down to the
floor level to assist with emergency vent opening.
