8.1.2 VERTICAL INSTALLATION

This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor. See
accessories 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" 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" 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 sealant 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
f i r e - p a r t s . c o m
tighten. This will prevent any materials, such as insulation, from fi lling up the 1" air space
around the pipe.

USING FLEXIBLE VENT COMPONENTS

DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND ELBOWS.
SPACERS ARE ATTACHED TO THE INNER FLEX PIPE AT PREDETERMINED INTERVALS TO MAINTAIN AN EVEN
AIR GAP TO THE OUTER FLEX 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

KEEP IT PULLED TIGHT.
MUST NOT BE REMOVED.
For safe and proper operation of the appliance, follow the venting
instructions exactly.
All inner fl ex pipe and outer fl ex pipe joints may be sealed using high
temperature sealant 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
SPACERS
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" as identifi ed
by the stamp only on the outer fl ex pipe.
