Figures 15 and 16 show examples of horizontal termi-
nation arrangements using two 90° elbows (Rigid
Vent).
NOTE:
1. A maximum of two 90° elbows are permitted.
2. A minimum of 10' (3m) vertical from base of unit is
required if two 90° elbows are used.
3. Minimum distance between elbows is 2' (610mm).
4. Determine the permitted range of horizontal termi-
nation arrangement by using chart above and
deducting 3' (914mm) from the maximum horizontal
distance for the second 90° elbow.

•
Flex vent shall use the spacer springs as included
every foot to ensure proper vent operation.
•
The 4" x 7" flex system may be used for all sidewall
applications and vertical venting up to 35' (10.7m).
•
Flex shall be properly supported so there are no
sags in the system. Supports must be used at least
every 24" (610mm) on horizontal section and every
36" (914mm) on vertical. Wire or metal stripping
may be used to support the venting.
•
For 4" x 7" flex, the 7" flex has an outside diameter
of 7 " (191mm) and if installed in a chase the
inside diameter of the chase should be 9 "
(241mm) minimum.
•
Lengths of co-axial flex may be joined together
using a flex connector kit (GFPVCK) only, maximum
1 kit per installation.
An extension collar is included with side wall cap kits
to simplify the connection of the flex pipe to the fire-
place. Refer to Page 13, Figure 22.
ATTENTION: Spacer springs must be installed when
installing flexible venting systems.
Wrap spacer spring around flex flue pipe and overlap
spring ends approximately 2" (610mm). Tie one end
over the other like a shoelace tie, then reverse direc-
tion of spring ends. Lift up hooped spring and slide
both spring ends underneath hooped spring. Spring
spacers should be spaced at approximately 12"
(305mm) intervals for the length of pipe system. Once
the springs are placed around the flue pipe, slide the
flue section with spacer springs into the outer flex pipe.
