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-combusti-
ble. Install wall thimble into wall, obser-
ving 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 per
305 mm) can be maintained. A framed
opening is required to insert the thimble
halves. The thimble is adjustable for dif-
ferent wall thicknesses. Caulk around
outside edge of plates as necessary and
fasten to wall using suitable screws or
nails. The vent pipe must be sealed at
wall thimble as per code regarding con-
tinuous vapor barrier.
2. The system can now be assembled
22
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 posi-
tion 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 prevent
collection of condensate at any location
in the assembly. Fasteners must not
penetrate the components of the
system either when joining pipes and fit-
tings or using support straps. The
lengths of pipe may be cut on non-expan-
ded end using aviation snips or a hack-
saw (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.
