A. Stretch the inner  ex pipe to the required length
taking into account the additional length needed for
the  nished wall surface. Apply a heavy bead of the
high temperature sealant W573-0007 Mill Pac (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 3 #8 screws.
B. Using the outer rigid 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).
C. Insert the vent pipes through the  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. From inside the house, using silicone, seal between the vent
pipe and the  restop. Then slide the black trim collar over the
vent pipe up to the  restop.
E. If more vent pipe needs to be used to reach the appliance,
couple them together as illustrated. The vent system must
be supported approximately every 3 feet (0.9m) for both
vertical and horizontal runs. Use noncombustible 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.
