This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor.
See the “accessories” section to order specifi c kits required.
A. Determine the air terminal location, cut and frame a square opening,
as illustrated, in the ceiling and the roof to provide the minimum 1"
(25mm) 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. A vent pipe shield will prevent any materials such as
insulation, from fi lling up the 1" (25mm) air space around the pipe. Nail
headers between the joist for extra support.
B. 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 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 red RTV
silicone (W573-0002) (not supplied) between the pipe and the fi restop
assembly.
C. 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" (25mm) air space around the pipe.

For safe and proper operation of the appliance, follow the venting instructions
exactly.
The vent system must be supported approximately every 3 feet (0.9m) for
both vertical and horizontal runs. Use Wolf Steel Ltd. support ring assembly
or equivalent noncombustible strapping to maintain the minimum clearance to
combustibles for both vertical and horizontal runs.
All inner fl ex pipe and outer fl ex pipe joints may be sealed using high temperature
red RTV silicone W573-0002 (not supplied) or the high temperature sealant W573-
0007 Mill Pac (not supplied). However, the high temperature sealant W573-0007
Mill Pac (not supplied) must be used on the joint connecting the inner fl ex pipe and
the exhaust fl ue collar.
Use only approved fl exible vent pipe kits marked:
“Wolf Steel Approved Venting” or “E2” as identifi ed by the stamp only on the fl ex pipes.
Elbow
Spacers
• Do not allow the inner fl ex pipe to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight.
• Spacers are attached to the inner fl ex pipe at predetermined intervals to maintain an even air gap to the outer
fl ex pipe. This gap is required for safe operation. A spacer is required at the start, middle, and end of each
elbow to ensure this gap is maintained. These spacers must not be removed.
