Vertical Penetration Framing - Heat & Glo Soho-N-AU Installer's Manual

C. Vertical Penetration Framing
WARNING
Fire Hazard
Keep loose materials or blown
insulation from touching the
fl ue pipe.
• Hearth & Home Technologies requires
the use of an attic shield.
Installing the Ceiling Firestop
• Frame an opening 254 mm by 254 mm
whenever the system penetrates a ceiling/
fl oor (see Figure 6.3). A steeply slanted
roof may require an enlarged opening
size in order to maintain proper fl ue pipe
clearances.
• Frame the area with the same sized
lumber as used in ceiling/fl oor joist.
• When installing a top fl ue vertical ter-
mination appliance the hole should be
directly above the appliance, unless the
fl ue is offset.
• Do not pack insulation around the fl ue.
Insulation must be kept away from the
pipe.
Installing Attic Shield
Note: An additional ceiling fi restop is not
required if attic shield is used.
• Frame opening for attic shield.
• Attic shield may be installed above or
below ceiling (see Figure 6.4).
• Secure with three fasteners on each
side.
• Fold tabs at top of attic shield in toward
fl ue pipe. Tabs must keep fl ue pipe cen-
tered within shield.
• Field construct additional shield height if
insulation is deeper than height of attic
shield.
