Venting Installation

INSTALLATION PLANNING

There are two basic types of direct-vent instal- lation:

•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 available only in vent kit HTK (see Figure 14, page 11).

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 11 through 13 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 connections.

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-quar- ter 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.

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).

WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.
