Z-FLEX recommends that the installation be performed by an experienced professional who works with venting systems on a-regular
basis. 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 structure through a sidewall or the like, shall terminate not less than 12 inches (254 mm) above the ground
(see illustration # 2, page 4).
2. The termination of a system shall be located above the snow line in geographical areas where snow accumulates. The termination area
should be kept clear of snow and ice at all times.
3. The vent shall not terminate less than 7 ft. (2.13 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. (.91 m ) from any other building opening, 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 3” 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 venting system.
D. A termination must be used on all installations to assure proper operation and to prevent debris from entering the venting system.
