runs and elbows.
tight. A 1 1/4" air gap between the 4"
and 7" flex vent pipes 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. Spacers are attached
to the
predetermined intervals to maintain a
1-1/4" air gap to the 7" flex vent pipe.
These spacers must not be removed.
1. Stretch the 4" fl ex vent pipe to the required length taking into
account the additional length needed for the fi nished wall surface.
Slip the vent pipe 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 W573-0007 (not supplied).
NOTE: If using pipe clamps to connect vent components, 3
screws must also be used to ensure the connection cannot slip
off.
2. Using the 7" fl ex vent pipe, slide over the outer combustion air
sleeve of the air terminal and secure with 3 #8 screws. Seal using
high temperature sealant W573-0002 (not supplied).
3. 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).
4. 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 for both vertical and horizontal runs. Use noncombustible
strapping to maintain the minimum 1" clearance to combustibles.
The air terminal mounting plate may be recessed into the exterior wall
or siding by 1½", the depth of the return fl ange.

For safe and proper operation of the fi replace, follow the
venting instructions exactly.
All 4" fl ex vent pipe and 7" fl ex vent pipe joints may be
sealed using high temperature sealant W573-0002 (not
supplied) or the high temperature sealant W573-0002
Mill Pac (not supplied). However, the high temperature
sealant W573-0007 Mill Pac (not supplied) must be used
on the joint connecting the 4" fl ex vent and the exhaust
Use only approved fl ex vent pipe kits marked:
"Wolf Steel Approved Venting" as
identifi ed by the stamp only on the
