Venting Installation

INSTALLATION PLANNING

There are two basic types of direct-vent in- stallation:

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

determine the route your horizontal venting

will take. Do not secure the fireplace until

all venting has been installed. Some installa-

tions 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 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

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 center-line of the horizontal vent pipe. Mark the wall for a 10 3/4" x 10 3/4" square hole. Cut and frame the square hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, such as masonry block or concrete, a 8 1/2" hole with zero clearance is acceptable (see Figure 9).

Vent Opening

Detail)

Twist-Lock Procedure: The female ends of

the pipes have locking lugs (indentations).

These lugs will slide straight into matching

slots on the male ends of adjacent pipes. Push

pipe sections together and twist one section

clockwise approximately one-quarter turn

until the sections 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 twist-locked onto the flue collar as

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, pre-assembled

pipe sections may be installed as subassem-

blies for convenience.
