This label indicates a fire rated door requiring a gasket.
In commercial buildings in the United States, fire-rated
doors require special gaskets to prevent smoke from getting
through the opening during a fire. Smoke seals are designed
to accomplish this, and here are the steps for installing
them.
!! Steps !!
Typical Warnock and Hershey fire labelled door jamb. Check the
requirements for the door you're preparing to install the seal on.
Specific LSCs (life safety codes) and NFPA (National Fire Protection
Agency) codes require smoke seals on fire rated doors [1]. Locations
where fire rated doors are installed depend on these codes and are
reflected in the architect's _Door Schedule_ and _Hardware Schedule_.
Here are examples of typical fire-rated door locations:
* Stairwells [2] in multistory commercial or public buildings
* Mechanical or electrical equipment rooms
* Sleeping quarters egress doors in dormitories or motels with
interior corridor accesses; and
* Other areas where fire walls are required per plans and
specifications.
* _ This package is pre-labelled from the manufacturer for a
specific door. Select the smoke seal for the door you're working
on. For projects with a consolidated hardware schedule, individual
door openings may be labelled on the smoke seal packaging
furnished by the hardware supplier.
* Instructions contained in a smoke seal package contain
details for an individual product's installation. Open the
package the smoke seal is in. There should be specific
instructions for the product you're using; read them before
proceeding, since products may vary from one manufacturer to
another.
* Removing the rubber door silences where the smoke seal
will fit on a hollow-metal fire door jamb. Remove the mutes (door
silencers) from your door jamb [3] if it is equipped with them.
* Cleaning the jamb where the seal attaches with an alcohol
towelette provided with the smoke seal. Clean the surfaces where
the smoke seal will be attached. Most gasket type smoke seals are
self-adhesive, so removing any dust [4], oil, or other material
from the door jamb's surface is essential for proper adhesion.
* The smoke seal after cutting with a utility knife; the
angle needs to be close to 45 degrees, but doesn't have to be
perfect. Make a diagonal cut with the bulb edge of the smoke seal
at the long end using a utility knife [5]. The angle should be
close to 45 degrees, but doesn't have to be perfect, since the
material is soft and flexible.
* Peeling the protective tape off the adhesive surface of
the smoke seal. Peel the protective tape off the smoke seal,
beginning at the end where you've cut the angle in the previous
step.
* The first piece of gasket material installed at the jamb
head beginning at the latch side. Begin at the top of the jamb on
the strike side_ (the side where the lock is located), pressing
the seal against the edge of the frame about 1/16 of an inch
(1.58mm) from the door jamb.
* Pressing the seal in place along the door jamb header,
note the disconnected closer bracket at the bottom left corner.
Continue across the head of the jamb to the butt (hinge [6]) side,
being sure to press the seal tightly to the jamb material, and
avoiding stretching it (pulling on it) as you go.
* Cutting the seal with a utility knife against the butt
side of the jamb. Cut the material with a utility knife when
you've pressed it into the corner on the butt side.
* Complementary angle for a miter joint at the left side of
a door jamb. Cut a complementary angle on the remaining smoke
seal that will fit the angle you began with at the top of the
strike side of the jamb.
* The two angles meeting at the latch [7] side corner of
the jamb. Note they are flexible enough to meet tightly, even
though the cut isn't perfect. Press this angled cut onto the jamb
surface making sure it fits the opposite angle of the header seal
installed previously.
* Pressing the seal to the stop along the latch side of the
door jamb. Press the smoke seal onto the stop, moving down the
strike side of the door, making sure you keep it slightly off the
door stop so the bulb portion of the gasket has room to expand
when it's compressed by the door when it's closed.
* The seal on both sides of the jamb should extend to the
floor or threshold. Cut this section of gasket as close to the
threshold or floor [8] at the bottom of the door when you have
reached it.
* The butt side of the door's smoke seal goes on the jamb
itself, rather than the stop. Begin at the top of the door jamb
on the butt side, cutting the smoke seal square and overlapping
the head seal slightly. Note that this seal attaches to the
door's frame [9] on the frame adjacent to the doorstop, rather
than on the stop as in previous steps.
!! Tips !!
* Note that the smoke seal should not cover any special labels
attached to the door jamb by the manufacturer.
* Using a plastic cart to hold a stairway door open while
working on it. Prop doors open or remove closer arms to keep the
door out of the way while installing smoke seals.
