4.1.1 HORIZONTAL INSTALLATION
A.
Assemble the two halves of the vent sleeve by aligning the holes that
come together to make a rectangular shape (lip to the outside). Secure
using 6 of the screws supplied in the manual baggie.
NOTE: Screws not required in two blind holes.
B.
Fit the
fi
restop spacer into one end of the vent sleeve and secure through
the aligned holes on the top, bottom, and sides with the remaining 5
screws supplied.
If
fl
exible venting is to be used remove the rigid
fi
restop spacer.
The remaining hole is sized for
fl
exible venting.
This application occurs when venting through an exterior wall.
Having determined the air terminal location, cut and frame a hole
in the exterior wall 9 7/8” wide by 11 3/8” high to accommodate the
fi
restop sleeve assembly.
The length of the vent shield may be cut shorter for combustible
walls that are less than 8 1/2” thick but the vent
shield must extend the full depth of the combustible
wall.
C.
Insert the
fi
restop sleeve assembly into the wall,
mark the wall depth and trim the vent sleeve to suit.
The screws that secure the vent sleeve may need
to be repositioned to ensure a rigid assembly is
maintained.
D.
Apply a bead of caulking (not supplied) to the
inside surface of the
fi
restop
fl
ange and secure the
assembly to the wall. (Ensure that the rectangular
shaped assembly is installed to maintain 2” from the top
of the vent).
E.
Once the vent pipe is installed in it’s
fi
nal position, apply high
temperature sealant W573-0002 (not supplied) between the
pipe and the
fi
restop.
