Using Rigid Vent Components

AIR TERMINAL

Do not nail through the lower portion of the

flashing. Make weather-tight by seal- ing with caulking. Where possible, cover the sides and top edges of the flashing

	with roofing material.	FIGURE 23

bead of weatherproof caulking 2 inches above the flash- ing. 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 centered between the air intake and the air exhaust slots onto the air terminal. Tighten securely. FIGURE 23. Attach the vertical rain cap.

Spacers are attached to the 5" inner flex liner at prede- termined intervals to maintain a 1-1/4" air gap to the 8" outer liner. These spacers must not be removed.

7.If more liner needs to be used to reach the fireplace, follow the same procedure as found in EXTENDED HORI- ZONTAL AIR TERMINAL INSTALLATION. The vent system must be supported approximately every 3 feet for both ver- tical and horizontal runs. Use Wolf Steel support ring as- sembly or equivalent noncombustible strapping to main- tain a clearance to combustibles.

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 provided. FIGURE 24.

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

FIGURE 24

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.

HORIZONTAL AIR TERMINAL INSTALLATION

3.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.Move the fireplace into position. Meas- ure the vent length required between ter- minal 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 to the outer edge of the 5" inner collar of the fireplace. Attach the first vent component and secure using 3 self tapping screws. Repeat using 8" piping.

1.Follow the instructions for "Horizontal Air Terminal In- stallations", items 1 to 3.

2.Continue adding components alternating inner and outer venting. Ensure that all 5" venting and elbows have sufficient vent spacers attached and each component is securely fastened to the one prior. Attach the 5" telescopic

sleeve to the vent run.
