Fire Rated Enclosure
Installation Technique and Design
Advisory Manual
approved firestop sealant and thickness (typically 1/4” (6mm))
shall be as specified in an approved UL / ULC firestop design
listing. When there is not sufficient annular space around the
duct to run the Pyroscat Duct Wrap XL enclosure system
continuous through the fire rated assembly, the enclosure may
terminate above and below the floor/ceiling assembly or on
either side of a wall assembly as shown in Figure 2. When this
method is used, the Pyroscat Duct Wrap XL must be
mechanically attached on either side of the fire rated assembly
using one of the attachment methods described in Section D,
spaced a maximum of 1-1/2” (38mm) from the fire rated
assembly.
G. Support Hanger Systems
1) Grease ducts: Trapeze support hangers shall be spaced on
maximum 60 in. (1500 mm) centers. Hanger rods or straps
shall be anchored with steel drop in or wedge expansion type
masonry anchors. No additional protection is required for
hangers and supports meeting the requirements of the Table
below.
2) HVAC ducts: Trapeze support hangers shall be spaced on
maximum 60 in. (1500 mm) centers. Hanger rods or straps
shall be anchored with steel drop in or wedge expansion type
masonry anchors. No additional protection is required for
hangers and supports meeting the requirements of the Table
below.
9. Maintenance and Repair
No maintenance is required when installed in accordance with
Thermal Ceramics (TC) installation instructions. If damage is
limited to the foil facing, aluminum foil tape can be used to repair
the foil facing. If an area of blanket is found to be damaged the
following procedure must be incorporated. If the damaged area is
larger than 8” (203mm) x 8” (203mm) the entire wrap section must
be removed and replaced according to TC installation
instructions. If the damaged area is small (less than 8” (203mm)
x 8” (203mm)), the damaged area must be cut away and replaced
with a new section 1” (25mm) larger in length and width than the
cut out, such that the new section can be compressed tightly into
the cut out area. All cut edges of the new section must be taped
and sealed with aluminum foil tape. The new section must be
held in place with either pinning or banding per TC installation
instructions.
10. Limitations
Thermal Ceramics Pyroscat Duct Wrap XL shall be installed in
accordance with these installation instructions and
appropriate laboratory design listings. The integrity of
Pyroscat Duct Wrap XL systems is limited to the quality of the
installation.
