Slip the liner a minimum of 2" over the inner sleeve of the air terminal and secure with 3 #8 screws. Seal using a heavy bead of the high temperature sealant. 3. Repeat using 7" diameter aluminum flexible liner. 4. Thread the air terminal pipe assembly down through the roof. The air terminal must be located vertically and plumb. Attach the air terminal assembly to the roof support, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened. DO NOT CLAMP THE FLEXIBLE ALUMINUM LINER. 5. Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and slide it un-FIGURE 22 derneath the sides and upper edge of the shingles. Ensure that the air terminal is properly centered within the flashing, giving a 3/4" margin all around. Fasten to the roof. Do not nail through the lower portion of the flashing. Make weather-tight by sealing with caulking. Where possible, cover the sides and top edges of the flashing with roofing material. 6. Apply a heavy bead of weatherproof caulking 2 inches above the flashing. Slide the storm collar around the air terminal and down to the caulking. Tighten to ensure that a weather-tight seal between the air terminal and the collar is achieved. Attach the other storm collar centered between the air intake and the air exhaust slots onto the air terminal. Tighten securely. Attach the vertical rain cap. 13 Spacers are attached to the 4" inner flex liner at predetermined intervals to maintain a 1-1/4" air gap to the 7" outer liner. These spacers must not be removed. 7. If more liner needs to be used to reach the fireplace, couple them together as illustrated in FIGURE 13. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use Wolf Steel support ring assembly W010-0370 or equivalent noncombustible strapping to maintain a clearance to combustibles of 1". FIREPLACE VENT CONNECTION 1. Install the 4 inch diameter aluminum flexible liner to the fireplace. Secure with 3 screws and flat washers. Seal the joint and screw holes using the high temperature sealant Mill Pac. 2. Install the 7 inch diameter aluminum flexible liner to the fireplace. Attach and seal the joints. FIGURE 23 USING RIGID VENT COMPONENTS For optimum performance it is recommended that all horizontal runs have a . inch rise per foot. For safe and proper operation of the fireplace, follow the venting instructions exactly. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use Napoleon vent spacers W615-0033 every 3 feet and on either side of each elbow to maintain the minimum 1." clearance between the outer and inner vent pipes. Use Napoleon support ring assembly W010-0370 or equivalent noncombustible strapping to maintain the minimum 1" clearance to combustibles for both vertical and horizontal runs. All inner exhaust and outer intake vent pipe joists may be sealed using either Red RTV high temp silicone sealant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed using Mill Pac (not supplied). HORIZONTAL AIR TERMINAL INSTALLATION 1. Move the fireplace into position. Measure the vent length required between terminal and fireplace taking into account the additional length needed for the finished wall surface and any 1." overlaps between venting components. 2. Apply high temperature sealant Mill Pac to the outer edge of the 4" inner collar of the fireplace. Attach the first vent component and secure using 3 self tapping screws. Repeat using 7" piping. 3. Holding the air terminal (lettering in an upright, readable position), insert into both vent pipes with a twisting motion to ensure that both the terminal sleeves engage into the vent pipes and the sealant. Secure the terminal to the exterior wall and make weather tight by sealing with caulking (not supplied). The air terminal may be recessed into the exterior wall or siding by 1.", the depth of the return flange. FIGURE 24 VERTICAL VENTING INSTALLATION 1. Move the fireplace into position. 2. Fasten the roof support to the roof using the screws provided. FIGURE 16. The roof support is optional. In this case the venting is to be adequately supported using either an alternate method suitable to the authority having jurisdiction or the optional roof support. 3. Apply high temperature sealant to the outer edge of the inner sleeve of the air terminal. Slip a 4" diameter coupler a minimum of 2" over the sleeve and secure using 3 screws. FIGURE 25 4. Apply high temperature sealant to the outer edge of the of the outside sleeve of the air terminal. Slip a 7" diameter coupler over the sleeve and secure as before. FIGURE 19. Trim the 7" coupler even with the 4" coupler end. 5. Thread the air terminal pipe assembly down through the roof support and attach, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened. FIGURE 18. If the attic space is tight...
