4.2 USING FLEXIBLE VENT COMPONENTS
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 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” or “E2” as identifi ed by the stamp on the fl ex pipes.

Spacers
DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND ELBOWS.
KEEP IT PULLED TIGHT.
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
MUST NOT BE REMOVED.

WARNING
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 a minimum
of 3 screws.
B.
Using the outer fl ex pipe, slide over the outer
combustion air sleeve of the air terminal and secure with
a minimum of 3 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 (0.9m) for both vertical
and horizontal runs. Use non-combustible strapping to
maintain the minimum 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.
