the vent shield to restrict cold air from being drawn into the room or around the fi replace. Ensure that both spacer and shield
maintain the required clearance to combustibles. Once the vent pipe is installed in its fi nal position, apply sealant between
the pipe and the fi restop assembly.
3. In the attic, slide the vent pipe collar down to cover
up the open end of the shield and tighten. This will
prevent any materials, such as insulation, from fi lling up
the 1" air space around the pipe.

tight. A 1 1/4" air gap between the 4"
and 7" flex vent pipes all around is
required for safe operation. A spacer
is required at the start, middle and
end of each elbow to ensure this gap
is maintained. Spacers are attached
to the
predetermined intervals to maintain a
1-1/4" air gap to the 7" flex vent pipe.
These spacers must not be removed.

VERTICAL INSTALLATION

SHIELD
1. Determine the air terminal location, cut and frame a 9½" square opening in the ceiling
and the roof to provide the minimum clearance between the vent pipe and any combustible
material. Try to center the vent pipe location midway between two joists to prevent having to
cut them. Use a plumb bob to line up the center of the openings.
Do not fi ll this space with any type of material.

A vent pipe shield will prevent any materials such as insulation,
from fi lling up the 1" air space around the pipe. Nail headers
between the joist for extra support.
2. Apply a bead of caulking (not supplied) to the framework or
to the Wolf Steel vent pipe shield plate or equivalent (in the case
of a fi nished ceiling), and secure over the opening in the ceiling.
A fi restop must be placed on the bottom of each framed opening
in a roof or ceiling that the venting system passes through. Apply
a bead of caulking all around and place a fi restop spacer over

For safe and proper operation of the fi replace, follow the
venting instructions exactly.
All 4" fl ex vent pipe and 7" fl ex vent pipe joints may be
sealed using high temperature sealant W573-0002 (not
supplied) or the high temperature sealant W573-0002
Mill Pac (not supplied). However, the high temperature
sealant W573-0007 Mill Pac (not supplied) must be used
on the joint connecting the 4" fl ex vent and the exhaust
fl ue collar.
Use only approved fl ex vent pipe kits marked:
"Wolf Steel Approved Venting" as
identifi ed by the stamp only on the
7" fl ex vent pipe.
Six inches (6") is the minimum bend radius allowed for the
7" fl ex vent pipe.
For optimum performance it is recommended that all horizontal
runs have a minimum 1" rise per foot using fl exible venting.
