Page 3: Clearance To Combustibles
JOINT PROCEDURE (see illustration #1 and images 1, 2 & 3 below) The female end of each Z-Vent III component incorporates a silicone sealing gasket. Examine all components to insure that gasket integrity has remained during shipping. Gaskets must be in the proper position or flue gases could leak resulting in carbon monoxide poisoning. - Page 4 3/8 inch ID high temperature silicone for at least the first 6 inches (152 mm) and attached with a gear clamp or hose clamp (see image 8 & 9). The effluent must be disposed of according to local regulations. NOTE: Z-FLEX recommends using a neutralizer kit when using a condensate trap. A condensate pump may be required.

VERTICAL VENTING (see illustrations #3 & 4) NOTE: The vent termination above the roof line shall consist of a continuous section of vent pipe only (without any joints) and must be at least 3 ft. (1 m) to a maximum of 6ft. above the roof line and 2 ft. (.61 m) higher than any part of a structure within 10 ft. (3.1 m). - Page 7 (see illustration #6) NOTE: When Z-Vent must be extended above the roof line more than six (6) feet the Guy Band must be used to support the system. 1.

Page 8: Existing Masonry Chimney
EXISTING MASONRY CHIMNEY (see illustration #5) NOTE: A masonry chimney flue may be used to route Z-VENT if no other appliance vents directly into the same flue without a liner. Prior to beginning the installation, be sure that the existing chimney meets all national and local building codes. The chimney must be cleaned, removing all soot, debris and creosote before installing Z-VENT. -

When any of the previous installation procedures are completed, be sure to go over the entire system to make sure all joints are secure and sealed correctly. The seams and joints must be checked for tightness prior to using the venting system. A qualified inspector must check the entire system at least once annually following initial installation to maintain the Z-FLEX warranty. - Page 10 To activate the warranty, the end-user must complete and return the Z-Flex® Warranty Registration Card within ninety (90) days of installation of the Z-Vent. Upon written notice of any defects, Z-Flex® reserves the right to examine or establish reasonable proof of defective material or workmanship justifying replacement.
