Installation Procedure

Z-FLEX

16.

Enclose coaxial vertical pipes in any occupied areas above first floor, including closets

and storage spaces. The enclosure needs to support and maintain minimum

clearances to coaxial pipes/vent and may be framed and sheet rocked.

17.

Locate and mark center of coaxial pipe on roof.

18.

Review appliance manufacturer's installation instructions for clearances of vent to

combustible surfaces and cut appropriate sized hole in roof incorporating necessary

clearances.

ROOF TERMINATION SUPPORT

Center roof support over hole in roof and secure to top of roof.

Install 42" long rigid pipe included in vertical kit through roof support and tighten

roof support around outer rigid pipe and with provided 1/2" long screws ensuring

pipe is vertically plumb and extends below roofline approximately 1 foot below

lowest opening in roof or enough to facilitate connection to outer flexible pipe.

Inner flue pipe provided in 2DVK-VX kits are 48" longer than outer pipe and

include 4 additional coaxial flexible spacers.

Install spacers every foot on inner flue pipe and route inner flue pipe through 42"

long rigid pipe yielding a coaxial assembly.
