INSTALLATION PLANNING

There are two starter vent kits available for either a horizontal or a vertical installation:

•CHVK-58 Corner Horizontal Vent Kit - Intend- ed for corner or flush installations with less than 24" of horizontal distance to the termination.

•CVVK-58 - Ceiling Vertical Vent Kit - Intended for a straight vertical installation through a ceil- ing with less than 9' to a roof termination.

Horizontal Termination Installation IMPORTANT: Horizontal square terminations require only inner portion of wall firestop.

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 13 and 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 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 sec- tions together and twist one section clockwise approximately one-quarter turn until the sections are fully locked (see Figure 10). Note: Horizon- tal runs of vent must be supported every three feet. Use wall straps for this purpose.

3.Any straight pipe section, a 45° or 90° elbow can be used when first connecting the venting system to the fireplace. Elbows are designed to twist-lock into any of four 90° positions to direct the venting system to the desired loca- tion. 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 (see Figure 11).
