1. Move the fi replace into position. Measure the vent length required
between terminal and fi replace taking into account the additional length
needed for the fi nished wall surface and any 1¼" overlaps between vent-
ing components.
2. Apply high temperature sealant W573-0007 (not supplied) to the outer
edge of the 4" inner collar of the fi replace. Attach the fi rst 4" rigid vent pipe
component and secure using 3 self tapping screws. Repeat using the 7"
rigid vent pipe component.
NOTE: Before attaching elbows to the collars on the back of the
fi replace, 1 1/2" will need to be trimmed off the 4" collar.
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 mounting plate may be recessed into the exterior wall or siding by 1½", the depth of the return
fl ange.

1. Install the 4" fl exible vent pipe to the fi replace. Secure with 3 screws and
fl at washers. Seal the joint and screw holes using the high temperature sealant
W573-0007 (not supplied).
2. Install the 7" fl exible vent pipe to the fi replace. Attach and seal the joints
using the high temperature sealant W573-0002 (not supplied).

4. Thread the air terminal connector / vent pipe assembly down through the roof. The air
terminal must be located vertically and plumb. Attach the air terminal connector to the roof
support, ensuring that the top of the air terminal is 16” above the highest point that it penetrates
the roof. Figure 27. DO NOT CLAMP THE FLEXIBLE VENT PIPE.
5. Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing
over the air terminal connector leaving a min. 3/4” of the air terminal connector showing
above the top of the fl ashing. Slide the fl ashing underneath the sides and upper edge of
the shingles. Ensure that the air terminal connector 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. Figure 27.
6. Aligning the seams of the terminal and air terminal
connector, place the terminal over the air terminal
connector making sure the vent pipe goes into the hole in the terminal. Secure with
the three screws provided. Figure 27.
7. 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. Install the storm
collar around the air terminal and slide down to the caulking. Tighten to ensure that a
weather-tight seal between the air terminal and the collar is achieved. Figure 27.
8. If more vent pipe needs to be used to reach the fi replace, couple them together
as illustrated. The vent system must be supported approximately every 3 feet for both
vertical and horizontal runs. Use noncombustible strapping to maintain the minimum
1" clearance to combustibles. Figure 24.

USING RIGID VENT COMPONENTS
The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use Wolf Steel vent
spacers W615-0033 every 3 feet on either side of each elbow to maintain the minimum 1¼" clearance between the 7" rigid
vent pipe and 4" rigid vent pipes. Use Napoleon® support ring assembly W010-0370 or equivalent noncombustible strapping
to maintain the minimum clearance to combustibles for both vertical and horizontal runs.
