Install Instructions

Supports Systems:
The support system for the liner should be considered by this point in the install.
a. A support system such as below the breaching point in the wall for the system to rest on.
b. A support system such as suspending guy wires from an anchor plate at the chimney top affixed to guy bands
around the flex liner.
SMOOTHCORE® FLEX TYPICAL INSTALLATION
Advisory: For the reasons of safety and quality of installation, the flex liner system should be installed with two persons,
one person lowering the liner from the top of the masonry chimney, while the other person pulls the liner down from below.
1.
Determine if the masonry chimney, factory built chimney or
chase can accept the fitting that will connect to the
Smoothcore® flex liner by measuring the dimension of the
fitting that will be part of the flex liner system. Allow for ½ inch
(13mm) more than the dimension of the largest fitting for easy
optional installs).
2.
Connect Smoothcore® flex to the fitting and tighten all
connections. (See Illustrations 18-20 or 21-23)
3.
Tie a guide rope to the flex liner above the male connector so
as to prevent the rope from slipping off and lower the rope in
the structure to the awaiting person down below.

4.
Lower the fitting and flex through the chimney top opening
while the person below using the guide rope pulls the liner
down through to the breaching.
Note: In cases where the structure is unable to accommodate
the dimensions of the fitting, the installers may seek an
alternate option of attaching the fitting through an enlarged
breach accessing the liner from the mechanical room.
5.
Remove the rope to align the fitting & condensate tube in their
final positions. Connect the breach pipe and tighten all
connections. Route the tube to a suitable condensate drain
or neutralizer.
