ELBOW
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 needed for the
fi
nished wall surface.
Apply a heavy bead of 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” over the inner
sleeve of the air terminal and secure with 3
#8 screws.
B.
Using the outer
fl
ex 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
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 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 no greater than the depth
of its return fl ange.
