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.

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.
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.
