5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal is properly centered within the flashing, giving a 3/5" 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 flash- ing 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 termi- nal. Tighten securely. Attach the vertical rain cap.

Spacers are attached to the 5" inner flex liner at prede- termined intervals to maintain a 1-1/5" air gap to the 8" 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. 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 5 inch diameter	FIGURE39
aluminum flexible liner to the fire-
place. Secure with 3 screws and
flat washers. Seal
the joint and screw
holes using the high
temperature sealant
provided.
2. Install the 8 inch
diameter aluminum
flexible liner to the
fireplace. Attach and
seal the joints.

USING RIGID VENT COMPONENTS

For optimum performance it is recommended that all horizontal runs have a ¼ 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 W615-0033every 3 feet and on either side of each elbow to maintain the minimum 1¼" clearance be- tween the outer and inner vent pipes. Use Napoleon sup- port ring assembly W010-0380or equivalent noncombus- tible strapping to maintain the minimum 1" clearance to combustibles for both vertical and horizontal runs.

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 1¼" overlaps between venting compo- nents.

2.Apply high temperature sealant to the outer edge of the 5" inner collar of the fireplace. Attach the first vent compo- nent and secure using 3 self tapping screws. Repeat us- ing 8" 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 exte- rior wall and make weather tight by sealing with caulking (not supplied). The air teminal may be recessed into the exterior wall or siding by 1½", the depth of the return flange.

VERTICAL AIR TERMINAL INSTALLATION

1. Move the fireplace into position.

2. Fasten the roof support to the roof using the screws provided. The roof support is optional. In this case the vent- ing 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 5" diam- eter coupler a minimum of 2" over the sleeve and secure using 3 screws.

5.Apply high temperature sealant

to the outer edge of the of the out- side sleeve of the air terminal. Slip

a 8" diameter coupler over the sleeve and secure as before.Trim the 8" coupler even with the 5" 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. If the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminal assembly as it is passed through the attic.

The air terminal must be located vertically and plumb.

6. Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal is properly centered within the flashing, giving a 3/5" 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.
