steel venting system for use
with Category III appliances
FR
Z-FLEX recommends that an experienced
professional who works with venting
systems on a regular basis perform the
installation. These instructions are intended
as a guide to assist a professional installer.
When the Z-VENT system is installed, the
following should be observed:
1. A venting system that exits the structu-
re through a sidewall or the like, shall
terminate not less than 12 inches (254
mm) above the ground (see figure 6/a,
page 22).
2. The termination of a system shall be
located above the snow line in geo-
graphical areas where snow accumula-
tes. The termination area should be kept
clear of snow and ice at all times.
3. The vent shall not terminate less than 7
ft. (2. 1 3 m) above a paved sidewalk or
driveway.
4. The termination shall be 6 ft. (1.8 m) or
more from the combustion air intake of
any appliance.
5. The system shall terminate more than 3
ft. (0.91 m) from any other building ope-
ning, gas utility meter, service regulator
or the like.
6. Exterior mounted venting systems

should be enclosed below the roof line
with a chase to limit condensation and
protect against mechanical failure.
NOTES:
A. The Z-FLEX SPECIAL STAINLESS VENT
SYSTEM is for use only with appliances
having a positive vent pressure of 8" of
water column or less.
B. Except for installation in one and two
family dwellings, a venting system that
extends through any zone above that on
which the connected appliance is located
shall be provided with an enclosure
having a fire resistance rating equal to or
greater than that of the floor or roof
assemblies through which it passes.
C. Do not place any type of insulation in any
required air spaces surrounding the ven-
ting system.
D. A termination must be used on all instal-
lations to assure proper operation and to
prevent debris from entering the venting
system.
E. The Z-Vent system must be free to
expand and contract.
Pipe must be properly supported.
Vertical runs must use firestops as late-
ral support at each ceiling level and at
SVSHTX03
least one support collar at the base of
the vertical run.
For vertical runs exceeding 16' (4.88 m),
a support collar is required at 16' (4.88
m) intervals.
Horizontal runs require a loose fitting
metal strap or similar support at each
joint.
F. Examine all components for possible ship-
ping damage prior to installation.
G. Proper joint assembly is essential for a
safe installation. Follow these instruc-
tions exactly as written. Check severe-
ness of joints upon completion of assem-
bly.
H. Check for unrestricted vent movement
through walls, ceilings and roof penetr-
tions.
I. Different manufacturers have different
joint systems and adhesives. Do Not Mix
Pipe, Fittings or Joining methods from dif-
ferent manufacturers.
