For safe and proper operation of the fi replace, follow the venting instructions exactly.
1. Stretch the 4" fl ex vent pipe to the required length taking into account
the additional length needed for the fi nished wall surface. Slip the vent
pipe a minimum of 2" over the inner sleeve of the air terminal and secure
with 3 #8 screws. Apply a heavy bead of the high temperature sealant
W573-0007 (not supplied).
NOTE: If using pipe clamps to connect vent components, 3 screws
must also be used to ensure the connection cannot slip off.
2. Using the 7" fl ex vent pipe, slide over the outer combustion air
sleeve of the air terminal and secure with 3 #8 screws. Seal using high
temperature sealant W573-0002 (not supplied).
3. Insert the vent pipes through the fi restop maintaining the required
clearance to combustibles. Holding the air terminal (lettering in an upright,
readable position), secure to the exterior wall and make weather tight by
sealing with caulking (not supplied).
4. 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.
The air terminal mounting plate may be recessed into the exterior wall or siding by 1½", the depth of the return
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. Figure 24.
2. Stretch the 4" fl ex vent pipe to the required length. Slip the 4" fl ex vent pipe a minimum
of 2" over the inner sleeve of the air terminal connector and secure with 3 #8 screws. Seal
using a heavy bead of high temperature sealant W573-0007 (not supplied). Figure 25.
NOTE: If using pipe clamps to connect vent components, 3 screws must also
be used to ensure the connection cannot slip off.
3. Repeat using the 7" fl ex vent pipe, using a heavy bead of high temperature sealant
W573-0002 (not supplied). Figure 25.
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 26. 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 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 26.
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 26.
7. Apply a heavy bead of weatherproof caulking 2" above the fl ashing. Note: Maintain a mini-
mum 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 26.
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 23.
