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 speci
fi
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 tighten.
This will prevent any materials, such as insulation, from
fi
lling up the 1” air space around the
pipe.

8.2 USING FLEXIBLE VENT COMPONENTS
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
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.
22.1
ELBOW
SPACERS
DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND ELBOWS.
KEEP IT PULLED TIGHT.
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
MUST NOT BE REMOVED.
