INSTALLATION / FRAMING
WALL AND CEILING PROTECTION
This application occurs when venting through an exterior wall.
Having determined the air terminal location, cut and frame
a hole in an exterior wall with a minimum square opening of
8” W x 8” H.
IMPORTANT: For optimum performance, The vent pipe
should rise ¼” per foot of run.
1. Apply a bead of caulking all around and place the fi restop
spacer over the framework 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.
Secure the spacer in place using the 4 longer screws supplied.
Once the vent pipe is installed in its fi nal position, apply high
temperature sealant (not supplied) between the pipe and the
fi restop spacer.
Spacers are attached to the fl exible vent pile at predetermined intervals to maintain a
3
/4” air
gap to the outer fl exible vent
pipe. These spacers must not be removed.
1. Cut or frame a hole in an exterior wall with a minimum
rectangular opening of 8” W x 8” H. Secure the fi restop spacer
over the opening to the interior wall. (FIGURE 4)
2. Stretch the 3” diameter aluminum fl exible vent pipe to
the required length taking into account the additional length
needed for the fi nished wall surface. Apply a heavy bead of
the high temperature sealant. Slip the vent pipe a minimum
of 2” over the inner sleeve of the air terminal and secure with
3 #8 screws.
3. Using the 5” diameter fl exible vent pipe, slide over the outer
combustion air sleeve of the air terminal and secure with 3
#8 screws. Seal as before.
4. Insert the vent pipe through the fi restop maintaining the
required clearance to combustibles. Secure the terminal to
the exterior wall (lettering in an upright, readable position) and
make weather tight by sealing with caulking (not supplied).
5. If additional vent pipe is required, couple them together as
illustrated. The vent system must be suppored approximately
every 3 feet for both vertical and horizontal runs. Use non-
combustible strapping to maintain the minimum 1” clearance
to combustibles from the vent pipe.
Use only approved aluminum fl exible vent kits
marked:
“Wolf Steel Approved Venting” as
identifi ed by the stamp on the fl exible
vent pipe.
USING FLEXIBLE VENT COMPONENTS
AIR TERMINAL INSTALLATION
For safe and proper operation of the fi replace, follow the venting
instructions exactly.
All inner exhaust and outer intake vent pipe joints may be
sealed using either Red RTV high temp silicone sealant or
Black high temp Mill Pac with the exception of the fi replace
exhaust fl ue collar which must be sealed using Mill Pac
(W573-0007 not supplied).
