1. Secure the terminal to the terminal extension plate (see fi gure 18).
2. Stretch the 5” diameter 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 se-
cure with 3 #8 screws. Apply a heavy bead of the high temperature sealant
W573-0002 (not supplied).
3. Using the 8” diameter fl ex 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 clear-
ance to combustibles. Secure to the exterior wall and make weather tight
by sealing with caulking (not supplied).
5. Apply a heavy bead of the high temperature sealant, Mill Pac W573-0007 (not supplied) with the unit, to the inside of
the 5” liner approximately 1” from the end. Slip the vent pipe a minimum of 2” over the fi replace vent collar and secure with
3 #8 screws.
6. Using the 8” diameter fl ex vent pipe, 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.
7. 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 clearances to com-
bustibles.

Use only approved flex vent pipe kits marked:
“Wolf Steel Approved Venting” as
identified by the stamp only on the
8” outer liner.

For safe and proper operation of the fireplace, follow the venting instructions exactly.
All inner exhaust and outer intake vent pipe joists may be sealed using either red RTV high temperature silicone
sealant or black high temperature Mill Pac with the exception of the fireplace exhaust flue collar which must be
sealed using Mill Pac (not supplied).
NOTE: Eight (8”) inches is the minimum bend radius al-
lowed for the 8” diameter fl exible vent pipe.

WARNING
Do not allow the inside vent pipe to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. An even air
gap between the inner vent pipe and outer vent pipe 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.
See Figure 17 .
