USING FLEXIBLE VENT COMPONENTS

ELBOW
SPACERS
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 (not supplied).
HORIZONTAL AIR TERMINAL INSTALLATION
1. Stretch the 4" diameter aluminum fl exible liner to the re-
quired length taking into account the additional length needed
for the fi nished wall surface. Slip the liner a minimum of 2"
over the inner sleeve of the air terminal and secure with 3 #8
screws. Apply a heavy bead of the high temperature sealant
W573-0002 (not supplied).
2. Using the 7" diameter fl exible aluminum liner, slide over
the outer combustion air sleeve of the air terminal and secure
with 3 #8 screws. Seal as before.

The air terminal mounting plate may be recessed into
the exterior wall or siding by 1½", the depth of the return
fl ange.

3. Insert the liners through the fi restop maintaining the
required clearance to combustibles. Holding the air terminal
(lettering in an upright, readable position), secure to the ex-
terior wall and make weather tight by sealing with caulking
(not supplied).
W415-0612 / A / 11.05.07
Do not allow the inside liner
to bunch up on horizontal
or vertical runs and elbows.
Keep it pulled tight. A 1 1/4"
air gap between the inner liner
and the outer liner all around
is required for safe operation.
A spacer is required at the
start, middle and end of each
elbow to ensure this gap is
maintained.

Use only approved aluminum flexible liner kits
marked:
"Wolf Steel Approved Venting" as
identifi ed by the stamp only on the 7"
outer liner.
Six inches (6") is the minimum bend radius allowed for
the seven inch (7") diameter fl exible liner.
For optimum performance it is recommended that all
horizontal runs have a minimum 1" rise per foot using
fl exible venting.
4. Apply a heavy bead of the high temperature sealant
W573-0007 (not supplied) to the 4" inner collar of the fi replace
approximately 1" from the end. Slip the liner a minimum of 2"
over the fi replace vent collar and secure with 3 #8 screws.
5. Using the 7" diameter fl exible aluminium liner, apply
high temperature sealant W573-0002 (not supplied), slide a
minimum of 2" over the fi replace combustion air collar and
secure with 3 #8 screws.
6. If more liner needs to be used to reach the fi replace,
couple them together as illustrated. The vent system must
be supported approximately every 3 feet for both vertical and
horizontal runs. Use noncombustible strapping to maintain
the minimum 1" clearance to combustibles.

aluminum fl ex liner to the required length. Slip the liner
a minimum of 2" over the inner sleeve of the air terminal
connector and secure with 3 #8 screws. Seal using a heavy
bead of the high temperature sealant.
3. Repeat using the outer
aluminum fl ex liner.
4. Thread the air terminal
connector / liner assembly
down through the roof. The
air terminal must be located
vertically and plumb. Attach
the air terminal connector to
the roof support, ensuring that
the top of the air terminal is 16"
above the highest point that it
penetrates the roof.

1. Fasten the roof
support to the roof using
the screws provided. The
roof support is optional.
In this case the venting
is to be adequately
supported using either
an alternate method
suitable to the authority
having jurisdiction or the
optional roof support.
