FIREPLACE VENT CONNECTION
1.Install the 4” diameter aluminium fl exible liner to the
fireplace. Secure with 3 screws and fl at washers. Seal the
joint and screw holes using the high temperature sealant | FIGURE 20 |
|
2.Install the 7” diameter aluminium fl exible 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 or equivalent 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 as- sembly 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).

that all 4” venting and elbowsVENTING have suffi cient vent spacers
attached and each compo- nent is securely fastened to the one prior. Attach the 4” telescopic sleeve to the vent run.
Repeat using a 7” telescopic sleeve. Secure and seal as before. To facilitate completion, attach 4” and 7” couplers to the air terminal.
3.Install the air terminal. See item 3 of the Horizontal Air Terminal Installation. Extend the 4” telescopic sleeve; con- nect to the air terminal assembly. Fasten with self tapping screws and seal. Repeat using the 7” telescopic sleeve.
VERTICAL VENTING INSTALLATION
1.Move the fi replace into position.
2.Fasten the roof support to the roof using the screws pro- vided. 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.

3. Holding the air terminal (with the air defl ectors to the |
top and the lettering in an upright, readable position) insert |
the terminal 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). |

3.Apply high temperature seal- ant to the outer edge of the inner sleeve of the air terminal. Slip a 4” diameter coupler a minimum of 2” over the sleeve and secure using 3 screws.
4. Apply high temperature seal- ant to the outer edge of the of the outside sleeve of the air terminal. Slip a 7” diameter coupler over the sleeve and secure as before. Trim the 7” coupler even with the 4” coupler end.
5. Thread the air terminal pipe assembly down through the roof support and attach, ensuring that a minimum 16” of air terminal will penetrate the roof when fastened. The air terminal must be located vertically and plumb.
