10.With the flex vent assembly and the 48” long hard pipe com- ponents laid out on the floor, begin securing these parts to- gether. First, apply a generous bead of silicone sealant to the inside of the 4” diameter flex flue (not the end with the pre- installed connector), then slide the flex flue over the 4” diam- eter hard pipe flue. Be sure to overlap at least 1-1/4”. Secure this connection with a 4” diameter band clamp provided. Be careful not to damage or tear the flex flue when tightening clamp.

11.Repeat the connection process for the outer 7” diameter flex vent to hard pipe connection. Use silicone sealant at this joint also, overlap at least 1-1/4”, then secure the joint with the 7” diameter band clamp provided. Be careful not to damage or tear the flex vent pipe when tightening the clamp.

12.While the venting is still on the floor, assemble the roof jack components as shown in Figure 31 and pre-install the roof jack assembly to the hard pipe approximately 18” from the top end of the hard pipe.

13.Now the pre-assembled vent system may be carried to the roof, then lowered through the roof cutout opening (see step

5). Feed the flex vent end down through the roof opening and firestop/thimble assembly installed in steps 4 through 6.

14.Secure the roof support assembly to the roof sheathing with at least (4) nails/screws through each support bracket. Check that the combustible clearances through the roof framing will maintain at least a 1” clearance from the vent pipe.

15.Determine how high the vent terminal should be located above the roof line based on the roof pitch information shown in Figure 33. Adjust the vent system height by loosening the pre-installed roof support pipe clamp and sliding the vent pipe up or down as pre-determined, then re-tighten the pipe clamp. Install a couple of sheet metal screws through the pipe clamp into the outer hard vent pipe to lock in place.

16.Check to make sure that the bottom end of the flex vent is long enough to reach the fireplace adapter collars. If too long, trim off the extra flex vent not needed.
