INSTALLATION pLANNING

There are two basic types of direct vent

installation:

• Horizontal Termination

• Vertical Termination

Outside air flex installation is required for

both horizontal and vertical installation (see

page 13).

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.

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 and 15 on page 12 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 location of 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 8).

Note: Horizontal runs of vent must be sup-

ported every three feet. Use wall straps

for this purpose.

3. Assemble desired combination of pipe

and elbows to fireplace flue collar. If there

are long portions of venting run, pre-as-

sembled pipe sections may be installed

as subassemblies for convenience.

4. Carefully determine location where vent

pipe assembly will penetrate outside wall.
