2.
Break the Flue Restrictor into two pieces. Do this
by bending the part back and forth until it breaks
(see Figure 9).
NOTE:
On vertical venting
configurations you may
want to install the vertical
baffle (385-128). See flue
restrictor installation in-
structions.
Figure 6.
Flex Vent
The flex vent must be supported with the spacing be-
tween support intervals not exceeding 4 feet, with no
more than ½ inch sag between supports.
A support is required at each change in venting direc-
tion, and in any location where it is necessary to main-
tain the necessary clearance to combustibles. A simple
“up and out” installation (Figure 6) requires only
enough support to maintain the necessary clearance
to combustibles. However, the vent attachment point
and the firestop location are considered to be supports.
