Fire Hazard
Keep loose materials or blown insulation
from touching the flue pipe.
• Hearth & Home Technologies requires
the use of an attic shield.
Installing the Ceiling Firestop
• Frame an opening 22.9 cm by 22.9 cm whenever
the system penetrates a ceiling/floor (see Figure
30). A steeply slanted roof may require an en-
larged opening size in order to maintain proper
flue pipe clearances.
• Frame the area with the same sized lumber as
used in ceiling/floor joist.
• The ceiling firestop may be installed above or
below the ceiling joists when installed with an attic
insulation shield. It must be under joists between
floors that are not insulated. See Figure 31.
• Secure with 3 fasteners on each side. See
Figure 31.
• Do not pack insulation around the flue. Insulation
must be kept away from the pipe.
Installing Attic Shield
• Remove one shield from box.
NOTice: Cut previously installed batt insulation to
make room for the attic insulation shield.
• Wrap shield around pipe if pipe is already
installed in area to be insulated.
• Match the three holes in each side and fasten
with three screws to form a tube.
• Bend three tabs on the bottom of the shield
outward to allow attachment to the ceiling
firestop.
• Bend the remaining bottom tabs inward 90° to
maintain the air space between the pipe and the
shield. Set the shield on the ceiling firestop and
attach to the firestop.
• Bend all tabs inward 90° around the top of the
shield. These tabs must be used to prevent blown
insulation from getting between the shield and
flue pipe, and to maintain air space clearance.
