Vertical Air Terminal Installation; Fireplace Vent Connection - Napoleon Madison GD-80NT Installation & Operation Instructions

1. Fasten the roof support to the roof using the screws provided. 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.
2. Stretch the 5" diameter fl ex vent pipe to the required length. 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 W573-0002 (not supplied).
3. Repeat using 8" diameter fl ex vent pipe.
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 FLEX VENT PIPE.
5. Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing
over the air terminal and slide it underneath the sides and upper edge of the shingles. Ensure that
the air terminal is properly centred within the fl ashing, giving a 3/4" margin all around. Fasten to
the roof. Do not nail through the lower portion of the fl ashing. Make weather-tight by sealing with
caulking. Where possible, cover the sides and top edges of the fl ashing with roofi ng material.
6. Apply a heavy bead of weatherproof caulking 2" above the fl ashing. NOTE: Maintain a minimum
2" space between the air inlet base and the storm collar. 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 centred between the air
intake and the air exhaust slots onto the air terminal. Tighten securely. Attach the vertical
rain cap.
7. If more liner needs to be used to reach the fi replace, couple them together as illus-
trated in Figure 19. The vent system must be supported approximately every 3 feet for
both vertical and horizontal runs. Use noncombustible strapping to maintain clearances to
combustibles.
1. Install the 5" diameter aluminium fl exible liner to the fi replace. Secure with 3
screws and fl at washers. Seal the joint and screw holes using the high temperature
sealant Mill Pac W573-0007 (not supplied).
2. Install the 8" diameter aluminium fl exible liner to the fi replace. Attach and seal
the joints with high temperature sealant W573-0002 (not supplied).
