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 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 twist-lock connections.

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).

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 ap-

proximately 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.
