Side wall venting installation
(see figure 6/a below)
1. Penetrating a combustible wall requires
the use of a wall thimble.
The pipe may be mortared in directly
without using a wall thimble, if the wall is
non-combustible. Install wall thimble into
wall, observing the aforementioned
rules and/or local building codes.
Select the point of wall penetration
where the minimum 1/4 " per foot of
slope (6.4 mm-0.25 in. per 305 mm-12
in.) can be maintained.
A framed opening is required to insert
the thimble halves.
The thimble is adjustable for different
wall thicknesses.
Caulk around outside edge of plates as
necessary and fasten to wall using sui-
table screws or nails.
The vent pipe must be sealed at wall
thimble as per code regarding conti-
nuous vapor barrier.
2. The system can now be assembled
through the thimble (attach the termi-
nation first - note "UP" arrow) and then
back to the appliance as per illustration
using JOINT PROCEDURE as described
on page 21.
A gear clamp (or locking band) must be
installed around the pipe on the inside of
wall to trap pipe in position so that the
system cannot be moved in or out of
wall. This applies to both combustible
and non-combustible walls.
3. The system must be supported along its
horizontal length at all elbow locations
and joints (every forty-eight inches or
less) using straps around pipes maintai-
ning clearance to combustibles as per
table on page 21.
Any horizontally installed portion of a
venting system shall have a slope
(upwards for Category II, III, or IV applian-
ces or downwards for Category III or IV
appliances) not less than 1/4" (6.4
mm) every 12 inches (305 mm) to pre-
vent collection of condensate at any
location in the assembly. Fasteners
must not penetrate the components of
the system either when joining pipes
and fittings or using support straps.
The lengths of pipe may be cut on non-
expanded end using aviation snips or a
hacksaw (24 tpi).
The cut end must be filed or sanded
smooth before joining. When installing
the condensate tube be sure to form a
trap by means of a 3" (76.2 mm) loop fil-
led with water.
This tube must be 3/8" (10 mm) ID high
temperature silicone for at least the
first 6 inches (152 mm) and attached
with a gear clamp or hose clamp. The
effluent must be disposed of according
to local regulations.
NOTE: Z-FLEX recommends using a neutra-
lizer kit when using a condensate trap. A
condensate pump may be required.
