AIR INLET BASE

5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal connector leaving a min. 3/4” of the air terminal connector showing above the top of the flashing. Slide the flashing underneath the sides and upper edge of the shingles. Ensure that the air terminal connector is properly centred 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 flashing with roofing

7.If more liner needs to be used to reach the fireplace, couple them together as illustrated. The vent system must be supported approximately every 3 feet for both vertical and hori- zontal runs. Use noncombustible strapping to maintain a clearance to combustibles of 1".

FIREPLACE VENT CONNECTION

1.Install the 5 inch diameter aluminium flexible liner to the fireplace. Secure with 3 screws and flat washers. Seal the joint and screw holes using the high temperature seal- ant Mill Pac.

2.Install the 8 inch diameter aluminium flexible liner to the fireplace. Attach and seal the joints.

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 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 assem- bly 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 seal- ant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed us- ing Mill Pac (not supplied).

HORIZONTAL AIR TERMINAL INSTALLATION

FIGURE 25

1.Move the fireplace into po- sition. Measure the vent length required between terminal and fireplace taking into account the

additional length needed for the finished wall surface and any 1¼" overlaps between venting components.

2.Apply high temperature sealant Mill Pac to the outer edge of the 5" inner collar of the fireplace. Attach the first vent compo- nent and secure using 3 self tapping screws. Repeat using 8" piping.

3. The heat shield must be	FIGURE 26

ing horizontally with no verti-
cal rise. Remove the two
screws nearest the vent col-
lars on the top of the fireplace.
Align the vent shield (sup-
plied) and secure.

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.

EXTENDED HORIZONTAL AIR TERMINAL

INSTALLATION

1.Follow the instructions for "Horizontal Air Terminal In-

stallations", items 1 to 3.

2.Continue adding compo- nents 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" tel- escopic sleeve.
