USING RIGID VENT COMPONENTS
For safe and proper operation of the fireplace, follow
the venting instructions exactly.
Horizontal runs may have a zero inch rise per foot using
Simpson Dura-Vent or Napoleon rigid venting compo-
nents.
The vent system must be supported approximately every 3
feet for both vertical and horizontal runs. Use Napoleon
vent spacers WS-615-33 or equivalent every 3 feet and
either side of each elbow to maintain the minimum 1¼"
clearance between the outer and inner vent pipes. Use
noncombustible strapping to maintain the minimum 2"
clearance to combustibles for both vertical and horizontal
runs.
FIREPLACE VENT CONNECTION
1. Apply high temperature sealant to the outer edge of
the 4" inner collar of the fireplace. Attach the first vent
component and secure using 3 self tapping screws. Re-
peat using 7" piping.
2. Slide the insulation sleeve over the 7" pipe. The insu-
lation sleeve is only required for the first 2 feet off the fire-
place or from the fireplace to the first firestop spacer (which-
ever distance is less) and needs only a 1" clearance. Fig-
ure 34.
Ensure that the insulation sleeve is pulled tight to the
fireplace after all vent components are installed.
HORIZONTAL AIR TERMINAL INSTALLATION
1. Move the fireplace into position. Measure the vent length
required between terminal and fireplace taking into ac-
count the additional length needed for the finished wall
surface and any 1¼" overlaps between venting compo-
nents.
2. Holding the air terminal (lettering in an upright, read-
able 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). Figure 29.
The air terminal mounting plate may be recessed into
the exterior wall or siding by 1½", the depth of the return
flange.
INSTALLATION
VERTICAL VENTING INSTALLATION
1. Move the fireplace into position.
2. Fasten the roof support to the roof using the screws
provided. FIGURE 31. The roof support is optional. In this
case the venting is to be adequately supported using ei-
ther 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.
4. Apply high temperature seal-
ant 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. Trim
the 7" coupler even with the 4" cou-
pler end. FIGURE 35.
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 fas-
tened. FIGURE 33.
If the attic space is tight, we recommend threading the Wolf
Steel vent pipe collar or equivalent loosely onto the air termi-
nal assembly as it is passed through the attic. FIGURE 28.
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 termi-
nal and slide it underneath the sides and upper edge of
the shingles. Ensure that the air terminal is properly cen-
tred 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 flash-
ing with roofing material.
7. Apply a heavy bead of waterproof 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 centred between
the air intake and air exhaust slots onto the air terminal.
Tighten securely. Attach the rain cap.
8. Continue adding rigid venting sections, sealing and
securing as above. Attach a 4" collapsed telescopic pipe
to the last section of rigid piping. Secure with screws and
seal. Repeat using a 7" telescopic pipe.
9. Run a bead of high temperature sealant around the
outside of the 4" elbow. Pull the adjustable pipe a mini-
mum 2" onto the elbow. Secure with 3 screws. Repeat with
the 7" telescopic pipe.
10. In the attic, slide the vent pipe collar down to cover up
the open end of the shield and tighten. This will prevent
any materials, such as insulation, from filling up the 1" air
space around the pipe.
