2.Direct vent pipe sections and components are designed with special twist-lock connections.

Twist-Lock Procedure: The female ends of the pipes have lock- ing lugs (indentations). These lugs will slide straight into match- ing 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 col- lar. 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. If there are long portions of venting run, pre-as- sembled pipe sections may be installed as subassemblies 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" x 10" 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 7 3/4" hole with zero clearance is acceptable (see Figure 9).

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

6.Noncombustible Exterior Wall: Position the horizontal vent cap in the center of the 7 3/4" round hole and attach to the exte- rior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around the outside edges to make a seal be- tween it and the outside wall. Note: The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.
