VENTING INSTALLATION
SLP-HSFTK – HORIZONTAL TERMINATION
KIT
Figure 46
Installation Instructions
1. Set the unit in place and survey how best to vent the
unit.
2. A wall square firestop
MUST BE
installed if the vent
passes through a ceiling or exterior combustible wall.
Cut a 9" wide x 9" high (229 x 229 mm) opening
through the wall or framing. A wall rectangular firestop
MUST BE
installed if the vent passes through interior
walls. In that case, cut a 10" wide x 10" high (254 x
254 mm) opening through the wall or framing. The
framing members may need to be reinforced. Posi-
tion the firestop on the hole previously cut and secure
with screws or nails (not provided). Run vent pipe
through firestop. The gap between the vent pipe and
the firestop may be sealed.
3. If the house has vinyl siding, after the termination cap
location has been decided, mark and cut the vinyl sid-
ing around the termination cap so that the cap can be
mounted flush to the wall.
4. Attach the SLP flex starter onto the starting collar on
the unit. Align seam of the pipe and seam of collar
to allow engagement. Rotate the SLP flex starter to
lock onto appliance. Install three (3) self tapping #10
screws through the SLP flex starter into the starting
collar of the appliance.
5. Slide one end of the 4" flex pipe over the inner pipe of
the SLP flex starter that is attached to the unit. Se
-
cure the flex pipe to the inner of the SLP flex starter
with one (1) small band clamp and three (3) self tap-
ping #10 screws.
6. Slide the 6
5
⁄
8
" flex pipe over the outer pipe of the SLP
flex starter that is attached to the unit. Secure the
flex pipe to the outer of the SLP flex starter with one
(1) large band clamp and three (3) self tapping #10
screws.
7. Remove the slip section from the termination cap.
8. Attach the SLP inner flex adapter to the inner pipe of
the slip section for the termination cap using three (3)
self tapping #10 screws.
9. Attach the SLP outer flex adapter to the outer pipe of
the slip section for the termination cap using three (3)
self tapping #10 screws.
10. Extend 4" inside flex pipe to reach the inner flex
adapter on the slip section of the termination cap
and install spacer springs. Spacer springs should be
equally spaced to prevent the inside and outside flex
pipe from touching each other and should be placed
in locations where the vent must bend.
11. Extend 6
5
⁄
8
" outside flex pipe to reach the outer flex
adapter on the slip section of the termination cap.
12. Slide 4" inner flex pipe over the inner flex adapter on
the slip section and secure it with one (1) small band
clamp and three (3) self tapping #10 screws.
13. Slide 6-5/8" outer flex pipe over the outer flex adapter
on the slip section and secure it with one (1) large
band clamp and three (3) self tapping #10 screws.
14. Carefully form the flexible duct so the end attached to
the slip section aligns with the 6.8" diameter opening
in the SLP-FS 1" firestop.
CAUTION! DO NOT crush, distort, or otherwise mod
-
ify the dimension of the flexible vent.
Damage
could cause appliance to overheat or have perfor-
mance issues.
15. Install the termination cap to the exterior wall with four
(4) #8 x 3" screws provided. In some installations the
flexible vent may need to pass through the SLP-FS
wall shield firestop. The flexible vent outside diame
-
ter exceeds the diameter of the hole in the SLP-FS.
The diameter of the inner hole of the SLP-FS will
need to be increased from 6
3
⁄
4
" to 7
1
⁄
4
". This modifica
-
tion can be made by trimming ¼" evenly around the
circumference of the inner hole in the SLP-FS. This
modification is not required in installations where the
SLP slip section projects through the SLP-FS.
16. Install the slip section on the end of the flex onto the
collars on the termination cap. Ensure that the two
overlap at least 1
1
⁄
2
".
17. When using aluminum or vinyl siding, finish the edges
of the siding around the termination cap with "J chan-
nel" and caulking to prevent water from leaking into
the building.
WARNING!
Refer to your fireplace homeown
-
er’s manual for the minimum and maximum
venting requirements of your fireplace and for ap
-
proved horizontal vent termination locations prior
to installation. Failure to
do so may cause fire haz
-
ard.
WARNING!
Any vertical sidewall horizontal
run must have a
1
⁄
4
" rise for every 12" of run
towards the vent termination.
NEVER ALLOW the
vent pipe to run down. This could cause high tem
-
peratures and may present a fire hazard.
WARNING!
Termination cap must be posi
-
tioned so the embossed arrow is pointed up.
WARNING!
This flexible pipe termination kit is
ONLY for horizontal terminations with one (1)
90° bend.
