WARNING: Use
UL approved Category III
vent material only. No other
vent material is permitted.
CAUTION: Follow the
vent manufacturer's
installation instructions as
design might vary from
manufacturer to
manufacturer.
Horizontal Vent Installation continued.
Use 4 hollow wall anchors, at least
1/8 inch (0 .32 cm) in diameter and of
appropriate length for the thickness of
the sheathing, if sheathing is particle
board or other composite material .
Use 4 #10x1-1/4" wood screws for
plywood, solid wood sheathing or
members . Use suitable masonry anchors
when passing through solid masonry
walls . Reinstall the decorative sheathing
around the faceplate . This assembly may
be painted to match the exterior decor .
Apply silicone sealant or silicone/latex
caulk around the vent section where
it passes through the plate and around
the plate where it is attached to the
structure . This will provide a weather
seal to keep moisture outside the
building . Ensure a sufficient seal is
made . Now attach the female end of
the air intake tee to the male end of the
3"/5" concentric vent pipe .
Push firmly on the air intake tee until
the outer jacket has made contact with
the snap ring located on the male end of
the 3"/5" concentric vent pipe section .
When fully assembled the outer female
end will overlap the male end 1 inch
(25 .4 mm) .
Use the self-tapping screws provided
with the vent kit to connect the two
outer pipes .
Seal the over lapping area of the outer
pipe (5" concentric pipe) with a thick
bead of caulk .

Example A: Typical Horizontal Termination
w/ 7/8" per foot DOWNWARD Slope
Install the appliance adapter onto the
appliance and use (4) four screws to
secure the appliance adapter to the
appliance . Now attach other required
vent and air intake material between
the appliance adapter and the horizontal
vent termination .
Maintain the proper clearance between
the vent pipe and combustible or non-
combustible material as required by the
vent manufacturer .
There is a 1" (2 .5 cm) minimum
clearance required between air
intake pipe and combustible or non
combustible material .
Proper support be provided for the vent
and air intake pipes as mentioned in the
venting section .
Support method used should isolate
the vent pipe from floor joist or other
structural members to help prevent the
transmission of noise and vibration .
Do not support, pin, or otherwise
secure the venting system in a way that
restricts the normal thermal expansion
and contraction of the chosen venting
material .
