Example B: Typical Horizontal Termination
w/ 1/4” per foot UPWARD Slope
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).
Orient the air intake connection on the
tee to its desired direction.
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.
Attach the female end of the vent pipe
from the water heater to the male end of
the vent outlet connection of the air
intake tee. See venting section for
appropriate pipe lengths.
Attach the female end of the air intake
from the water heater to the male end of
the air intake connection of the air
intake tee.
Install the appliance adapter onto the
appliance outlet and inlet and clamp as
required. Now attach other required
vent and air intake material between the
appliance adapter and the air intake tee.
Maintain the proper clearance between
the vent pipe and combustible or non-
combustible material as required by the
vent manufacturer.
There is no 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.
