II- The Flex-Flex adapter is used to connect two flexible liners together. Its
upper side is a single wall with 4 screw holes and its lower side has two walls
whose outer wall also has 4 screw holes
(Figure 14)
. It is installed between
two flexible liners, usually halfway through the chimney.
Ill- The female adapter is used to connect the flexible length to a rigid duct.
Its upper side reversed edge, and the lower side has two side walls, which
the outer wall has screw holes
(Figure 15)
. It is installed on the top of the
flexible length.
I. Assembly steps for the Flex-Flex adapter with the flexible liner
1. Before official installation
1.1. If cutting the liner on the field is required, make sure the cut
is square. Make a marker line on both ends of the liner at 1 5/8”
from each end. That mark will act as a reference point when the
adapters are fully seated onto the flex liner.
(Figure 16)
.
1.2. To make sure that everything is airtight before putting the
sealant between both tubes, do a dry fit test by pushing the
liner into the adapter until it reaches the bottom of
the flare between the inner wall and the outer wall, then
remove it
