Side wall venting installation
ENG
(see figure 6/a below)
FR
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 ope-
ning is required to insert the thimble hal-
ves. The thimble is adjustable for diffe-
rent wall thicknesses. Caulk around out-
side 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
20
through the thimble (attach the termi-
nation first - note "UP" arrow) and then
back to the appliance as per illustration
using JOINT PROCEDURE. A gear
clamp (or locking band) must be instal-
led 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 20.
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 filled with water.
This tube must be 3/8" ID high tempe-
rature 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.
