INSTALLATION PLANNING
There are two basic types of
•Horizontal Termination
•Vertical Termination
Horizontal Termination Installation IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Hori- zontal installations using round termination require exterior portion of wall firestop (see Figure 14, page 12).
1. Set the fireplace in its desired location and deter- |
mine the route your horizontal venting will take. |
Do not secure the fireplace until all venting has |
been installed. Some installations require sliding |
the fireplace in and out of position to make final |
venting connections. Figures 14 through 18 on |
pages 12 through 14 show different configura- |
tions 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 vent- |
ing 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 |
5.Carefully determine the location where the vent pipe assembly will penetrate the outside wall. The center of the hole should line up with the

Detail)
pipes have locking lugs (indentations). These |
lugs will slide straight into matching slots on |
the male ends of adjacent pipes. Push pipe sec- |
tions together and twist one section clockwise |
approximately |
are fully locked (see Figure 8). Note: Horizontal |
runs of vent must be supported every three feet. |
Use wall straps for this purpose. |
3. Use a 45° elbow to connect venting system |
to fireplace flue collar. The elbow is designed |
to be |
described in step 2. IMPORTANT: Do not |
attempt to alter the configuration of the elbow |
by cutting, twisting, bending, etc. |
4. Assemble the desired combination of pipe and |
elbows to the fireplace flue collar. If there are |
long portions of venting run, |
pipe sections may be installed as subassem- |
blies for convenience. |
