USING FLEXIBLE VENT COMPONENTS

FIGURE 20

ELBOW

Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1 1/4" air gap between the inner liner and the outer liner all around is

SPACERS required for safe operation. A spacer is required at the start, middle and end of each elbow to ensure this gap

is maintained.

For safe and proper operation of the fireplace, fol- low the venting instructions exactly.

2.Stretch the 5" diameter flexible liner to the required length. Slip the liner a minimum of 2" over the inner sleeve of the air terminal connector and secure with 3 #8 screws. Seal using a heavy bead of the high temperature sealant.

3.Repeat using 8" diameter fl exible

liner.

4.Thread the air terminal connector/

pipe assembly down through the roof. The air terminal must be located vertically and plumb. Attach the air terminal connector to the roof sup-

All inner exhaust and outer intake vent pipe joints 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).

Use only approved flexible liner kits marked:

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

For safe and proper operation of the fireplace, follow the venting instructions exactly.

NOTE: Eight (8”) inches is the minimum bend radius allowed for the 8” diameter fl exible liner.

HORIZONTAL AIR TERMINAL INSTALLATION

1.Secure the terminal to the terminal extension plate (see figure

21).

2.Stretch the 5" diameter fl exible liner to the required length tak- ing into account the additional length needed for the fi nished wall surface. Slip the liner a minimum of 2" over the inner sleeve of the

air terminal and secure with

3 #8 screws. Apply a heavy		CAULKING

The air terminal mounting plate may be recessed

into the exterior wall or siding by 1½", the depth of the return flange.

4.Insert the liners through the fi restop maintaining the required clearance to combustibles. Holding the air terminal (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, W573-0007 (not supplied) to the inside of the 5" liner approximately 1" from the end. Slip the liner a minimum of 2" over the fi replace vent collar and secure with 3 #8 screws.

6.Using the 8" diameter fl exible aluminium liner, apply high tempera- ture sealant W573-0002 (not supplied), slide a minimum of 2" over the fi replace combustion air collar and secure with 3 #8 screws.

VERTICAL AIR TERMINAL INSTALLATION

1.Fasten the roof support to the roof using the screws provided. 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.

port, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened.

DO NOT CLAMP THE FLEXIBLE ALU-

MINIUM LINER.

5.Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing over the air terminal and slide it underneath the sides and upper edge of the shingles. Ensure

that the air terminal connector is properly centred within the fl ashing, giving a 3/4" margin all around. Fasten to the roof. Do not nail through the lower portion of the fl ashing. Make weather-tight by sealing with caulking. Where possible, cover the sides and top edges of the flash- ing with roofi ng material.

6.Aligning the seams of the terminal and air terminal connector, place the terminal over the air terminal connector making sure the liner goes into the hole in the terminal. Secure screws provided.

7. Apply a heavy bead of weather-	FIGURE 24
proof caulking 2" above the fl ashing.
Note: Maintain a minimum 2" space
between the air inlet base and the storm
collar. Install the storm collar around the
air terminal and slide down to the caulk-
ing. Tighten to ensure that a weather-
tight seal between the air terminal and
the collar is achieved.

8.If more liner needs to be used to reach the fireplace, couple them together

as illustrated in Figure 25. The vent system must be supported ap- proximately every 3 feet for both vertical and horizontal runs. Use noncombustible strapping to maintain a clearance to combustibles of 1".
