USING FLEXIBLE VENT COMPONENTS

Use only approved aluminum flexi- ble liner kits marked:

"Wolf Steel Approved Venting" as identified by the stamp only on the 8” outer liner.

HORIZONTAL AIR TERMINAL INSTALLATION

FIGURE 19

1.Cut or frame a hole in an exterior wall with a minimum round or square opening listed on page 5. Secure the firestop spacer over the opening to the interior wall.

2.Stretch the 5" diameter aluminum flexible liner to the required length taking into account the additional length needed for the finished wall surface. Slip the liner a mini- mum of 2" over the inner sleeve of the air terminal and secure with 3 #8 screws. Apply a heavy bead of the high temperature sealant.

3.Using the 8" diameter flexible aluminum liner, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as before.

4.Insert the liners through the firestop maintaining the required clearance to combustibles. Holding the air termi- nal (lettering in an upright, readable position), secure to the exterior wall and make weather tight by sealing with caulking (not supplied).

5.Apply a heavy bead of the high temperature sealant, supplied with the unit, to the inside of the 5" liner approxi- mately 1" from the end. Slip the liner a minimum of 2" over the fireplace vent collar and secure with 3 #8 screws.

6.Using the 8" diameter flexible aluminium liner, apply sealant, slide a minimum of 2" over the fireplace combus- tion air collar and secure with 3 #8 screws.

EXTENDED HORIZONTAL

AIR TERMINAL INSTALLATION

Use the GD420 vent kit and couplers for this application.

If more than one length of liner needs to be used to reach the fireplace, couple them together as illustrated in FIGURE 20. Seal the joints using the same procedure as described in points 2 and 3. The vent system must be sup- ported approximately every 3 feet for both vertical and hori- zontal runs. Use Wolf Steel support ring assemblies, or equivalent noncombustible strapping to maintain the mini- mum 1" clearance to combustibles as well as to prevent sagging.

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.

VERTICAL AIR TERMINAL INSTALLATION

1. Fasten the roof support to

FIGURE 21

the roof using the screws pro-

 

vided. FIGURE 21. The roof sup-

 

port is optional. In this case the

 

venting is to be adequately sup-

 

ported using either an alternate

 

method suitable to the authority

 

having jurisdiction or the op-

 

tional roof support.

 

2. Stretch the 5" diameter alu-

 

minium flexible liner to the re-

 

quired length. Slip the liner a

 

minimum of 2" over the inner

 

sleeve of the air terminal and se-

 

cure with 3 #8 screws. Seal us-

 

ing a heavy bead of the high

 

temperature sealant.

 

3. Repeat using the 8" diam-

 

eter flexible aluminium liner.

4.Thread the air terminal pipe assembly down through the roof. The air terminal must be located vertically and plumb. Attach the air terminal assembly to the roof support, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened.

DO NOT CLAMP THE FLEXIBLE ALUMINIUM LINER.

5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air termi- nal and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal is properly centered within the flashing, giving a 3/4" margin all around. Fasten to the roof.
