F. Vertical Penetration Framing

WARNING

Fire Risk

Keep loose materials or blown insulation from touching the vent pipe.

•National building codes recommend using attic shield to keep loose materials/blown insulation from contacting vent.

•Hearth & Home Technologies requires the use of an attic shield.

Install the Firestop Spacer

•Frame an opening 10 in. by 10 in. whenever the vent system penetrates a ceiling/fl oor (see Figure 2.17).

•Frame the area with the same sized lumber as used in ceiling/fl oor joist.

•When installing a top vent vertical appliance the hole should be directly above the appliance, unless the fl ue is offset.

•Do not pack insulation around the vent. Insulation must be kept away from the pipe.

Note: The fi restop spacer is not required if attic insulation shield is used.

Install Attic Insulation Shield

•Frame opening for attic insulation shield.

•Attic insulation shield may be installed above or below ceiling (see Figure 2.18).

•Secure with three fasteners on each side.

•Fold tabs at top of attic shield in toward vent pipe. Tabs must keep vent pipe centered within shield.

•Field construct additional shield height if insulation is deeper than height of attic shield.
