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
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 instal-
led portion of a venting system shall
have a slope (upwards for Category II, III,
or IV appliances 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 con-
densate at any location in the assembly.
Fasteners must not penetrate the com-
ponents of the system either when joi-
ning 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 filled 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.
