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 approxi- mately 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						Figure 8 - Vent Pipe Connections
	collar. The elbow is designed to be twist-locked onto the flue
	collar as described in step 2. IMPORTANT: Do not attempt						Vent Opening
	to alter the configuration of the elbow by cutting, twisting,						Combustible Wall	10 3/4" Inside Framing
	bending, etc.
4.							10 3/4"	(273 mm)
	Assemble the desired combination of pipe and elbows to the						(273 mm)
	fireplace flue collar. If there are long portions of venting run,
	pre-assembled pipe sections may be installed as subassemblies						10 3/4"
	for convenience.

5.	Carefully determine the location where the vent pipe assembly
	will penetrate the outside wall. The center of the hole should						(Framing
	line up with the center-line of the horizontal vent pipe. Mark the

	hole in the exterior wall where the vent will be terminated. If						Noncombustible Wall
	the wall being penetrated is constructed of noncombustible
	material, such as masonry block or concrete, a 8				1	/2" hole with	8 1/2"
	zero clearance is acceptable (see Figure 9).						(216 mm)

6.	Noncombustible Exterior Wall: Position the horizontal vent
	cap in the center of the 8		1	/2" round hole and	attach to the
	exterior wall with four screws. Note: The four wood screws
	provided should be replaced with appropriate fasteners for
	stucco, brick, concrete or other types of sidings. Before attach-
	ing the vent cap to exterior wall, run a bead of non-hardening
	mastic (pliable sealant) around the outside edges to make a seal						Figure 9 - Vent Opening Requirements
	between it and the outside wall.

Combustible Exterior Wall: For vinyl siding, stucco or wood
exteriors, a siding standoff may be installed between the vent
cap and exterior wall. The siding standoff prevents excessive
heat from damaging the siding materials. Siding material
must be cut to accommodate standoff. Bolt the vent cap to the
standoff. Apply non-hardening mastic around outside edge of
standoff. Position the standoff/cap assembly in the center of
the 10	3	/4" square hole and attach to exterior wall with wood
screws provided (see Figure 11, page 9). The siding standoff
must sit flush against the exterior fascia material.
