INSTALLATION pLANNING
There are two starter vent kits available for
either a horizontal or a vertical installation:
• CHVK-58 Corner Horizontal Vent Kit - In
-
tended for corner or flush installations with
less than 24" of horizontal distance to the
termination.
• CVVK-58 - Ceiling Vertical Vent Kit - In
-
tended for a straight vertical installation
through a ceiling with less than 9' to a roof
termination.
Horizontal Termination Installation
IMPORTANT
: Horizontal square terminations
require only inner portion of wall firestop.
1. Set fireplace in its desired location and de
-
termine the route your horizontal venting
will take. Do not secure fireplace until all
venting has been installed. Some instal-
lations require sliding fireplace in and out
of position to make final venting connec
-
tions. Figures 14 through 18 on pages 13
and 14 show different configurations for
venting with horizontal termination that
will help you decide which application
best suits your installation. Check to see
if wall studs or roof rafters are in the path
of your desired venting route. If they are,
you may want to adjust the location of the
fireplace.
2. Direct vent pipe sections and components
are designed with special twist-lock con
-
nections.
Twist-Lock Procedure:
Female ends of
pipes have locking lugs (indentations).
These lugs will slide straight into match
-
ing slots on male ends of adjacent pipes.
Push pipe sections together and twist
one section clockwise approximately one-
quarter turn until sections are fully locked
(see Figure 10).
Note:
Horizontal runs of vent must be sup-
ported every three feet. Use wall straps
for this purpose
.
3. Any straight pipe section, a 45° or 90°
elbow can be used when first connecting
venting system to fireplace. Elbows are
designed to twist-lock into any of four 90°
positions to direct the venting system to
the desired location.
IMPORTANT:
Do not
attempt to alter the configuration of the
elbow by cutting, twisting, bending, etc.

4. Assemble desired combination of pipe
and elbows to fireplace flue collar. If there
are long portions of venting run, pre-
assembled pipe sections may be installed
as subassemblies for convenience.
5. Carefully determine the location where vent
pipe assembly will penetrate outside wall.
Center of hole should line up with center-
line of horizontal vent pipe. Mark the wall
for a 11
