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 con-
nector 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. Aligning the seams of the terminal
and air terminal connector, place the
terminal over the air terminal connector
making sure the liner goes into the hole in
the terminal. Secure with the three screws
provided.
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 caulk-
ing. Tighten to ensure that a weather-tight seal between the air
terminal and the collar is achieved.
8. If more liner needs to be used to reach the fi replace, couple
them together as illustrated in Figure 22. The vent system must be
supported approximately every 3 feet for both vertical and horizon-
tal runs. Use noncombustible strapping to maintain a clearance to
combustibles
of 1".

1. Install the 5" diameter fl exible
vent pipe liner to the fi re-
place. Secure with 3 screws and fl at washers. Seal the joint
and screw holes using the high temperature sealant W573-
0007 (not supplied) Mill Pac.
2. Install the 8" diameter fl exible
vent pipe to the fi replace.
Attach and seal the joints with high temperature sealant
W573-0002 (not supplied).

4. Holding the air terminal (with the
air deflectors to the top), insert into
both vent pipes with a twisting motion
to ensure that both the terminal sleeves
engage into the vent pipes and 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 flange.
1. Follow the instructions for
"Horizontal Air Terminal Instal-
lations", items 1 to 3.
2. Continue adding com-
ponents alternating inner and
outer venting. Ensure that all
5" venting and elbows have
suffi cient vent spacers attached
and each component is securely fastened to the
one prior. Attach the 5" telescopic sleeve to the
vent run.
Repeat using a 8" telescopic sleeve. Secure
and seal as before. To facilitate completion, attach
5" and 8" couplers to the air terminal.
3. Install the air terminal. See item 3 of the
Horizontal Air Terminal Installation. Extend the 5" telescopic sleeve;
connect to the air terminal assembly. Fasten with self tapping screws
and seal. Repeat using the 8" telescopic sleeve.
The vent system must be supported approximately every 3 feet for
both vertical and horizontal runs. Use Wolf Steel vent spacers every
3 feet and either side of each elbow to maintain the minimum 1¼"
clearance between the outer and inner vent pipes. Use Wolf Steel
support ring assembly or equivalent noncombustible strapping to
maintain the minimum clearance to combustibles for both vertical
and horizontal runs.
All inner exhaust and outer intake vent pipe joists may be sealed
using either Red RTV high temp silicone sealant or Black high
temp Mill Pac with the exception of the fireplace exhaust flue
collar which must be sealed using Mill Pac (not supplied).
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 venting components.
2. Apply high temperature sealant
W573-0007 (not supplied) Mill Pac to
the outer edge of the 5" inner collar of
the fi replace. Attach the fi rst vent com-
ponent and secure using 3 self tapping
screws. Repeat using 8" piping.
3. The vent heat shield must be installed only when terminating
horizontally. Remove the two screws nearest the vent collars on the
top of the fi replace. Align the vent shield (supplied) and secure.
Adjust the heat shield to touch the fi restop spacer.
