FastDoor ® XL
1. Product Description
Thermal Ceramics offers another innovation to our fire rated
enclosure line, the FastDoor duct access system. The FastDoor
system is comprised of a UL1978 tested and listed duct access
door and an ASTM E2336 tested and listed enclosure cover plate.
The duct access door is tested to be grease and fire tight when
immersed in a simulated grease pan fire per UL1978. The access
door is Union made and under UL follow-up inspection to ensure
the finest quality. An included and ready to install insulated cover
plate is compatible with FireMaster FastWrap XL and Pyroscat Duct
Wrap XL installation on grease or air ducts, and is the only single
layer door enclosure system available. This single layer of insulation
is only 1-1/2 inches thick and provides zero clearance to adjacent
combustibles and 2-hour rating per the stringent ASTM E2336 grease
duct enclosure standard. The FastDoor system provides for fast and
simple installation surpassing the requirements of NFPA 96 and the
International Mechanical Code.

cess at each change in direction and at intervals as required by code
and acceptable to the building official. FastDoor XL is a factory built
grease duct access door system providing zero clearance and 2-hour
fire rating with UL Listings per ASTM E2336 (HNKT G18) and UL1978
(YYXS.MH47995). FastDoor XL is
installed fire tight with NFPA 96 compliant high temperature gasket
and liquid tight with integral closed cell neoprene gasket. Installation

5. Installation
Materials and Equipment:
• FastDoor complete with duct door, insulated cover, cut-out
templates, and installation hardware
• Reciprocating saw, snippers, or torch to cut access hole in duct
• Drill and 3/8” bit
• Insulation knife
• 4” Aluminum foil tape
Installation of the duct access door: Peel off and place the duct
door cut-out template in the desired location. Retain the remainder
of the template as a guide to cut the enclosure insulation. Drill
3/8” holes at the marked locations. Cut the access hole along
the provided cut-out line. Install retaining clips at each 3/8” hole,
ensuring that the nut is centered in the hole. Locate the duct access
door over the access opening, aligning the holes and the retaining
clips. Loosely install all the wing nuts, using the extension nuts with
threaded rods on the four corners. Finger tighten each fastener until
snug.
Installation of the enclosure cover: The duct should be insulated
according to Thermal Ceramics installation instructions. Center the
retained insulation cut-out template over the duct access door, using
the two threaded rods protruding through the insulated duct as a
guide. Cut through the enclosure insulation all the way to the bare
duct. Seal the cut insulation using 4” wide aluminum foil tape. Install
the enclosure cover plate over the two threaded rods. Adjust the
duct insulation as necessary to allow for a tight overlap and no gaps
between the duct insulation and the enclosure cover. Install and
finger tighten the provided washers and wing nuts.
