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

4.2.1 HORIZONTAL AIR TERMINAL INSTALLATION

A. Stretch the inner fl ex pipe to the required length
taking into account the additional length needed for
the fi nished wall surface. Apply a heavy bead of the
Mill Pac sealant (W573-0007) (not supplied) to the
inner sleeve of the air terminal. Slip the vent pipe a
minimum of 2" (50.8mm) over the inner sleeve of the
air terminal and secure with 6 #8 screws.
B. Using the outer fl ex pipe, slide over the outer
combustion air sleeve of the air terminal and secure
with 6 #8 screws. Seal using Red RTV Silicone
(W573-0002) (not supplied).
C. Insert the vent pipes through the fi restop maintaining
the required clearance to combustibles. Holding the
air terminal (lettering in an upright, readable position),
secure to the exterior wall and make weather tight by
sealing with caulking (not supplied).
D. If more vent pipe needs to be used to reach the fi replace,
couple them together as illustrated. The vent system must
be supported approximately every 3 feet (0.9 meters) for
both vertical and horizontal runs. Use noncombustible
strapping to maintain the minimum 1" (25.4mm) clearance
to combustibles.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the
depth of its return fl ange.
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 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
SPACERS
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.
