USING FLEXIBLE VENT COMPONENTS

FIGURE 20

ELBOW

Do not allow the inside fl exible vent pipe to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1 1/4" air gap between the inner and the outer vent pipe

SPACERS all around is 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" fl exible vent pipe to the required length. Slip the vent pipe 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 vent pipe.

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 vent pipe kits marked:

"Wolf Steel Approved Venting" as iden- tified by the stamp only on the 8” outer vent pipe.

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 vent pipe.

HORIZONTAL AIR TERMINAL INSTALLATION

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

21).

2.Stretch the 5" diameter fl exible vent pipe to the required length taking 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 vent pipe assembly 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 sup- plied).

5.Apply a heavy bead of the high temperature sealant, W573-0007 (not supplied) to the inside of the 5" vent pipe approximately 1" from the end. Slip the vent pipe a minimum of 2" over the fi replace vent collar and secure with 3 #8 screws.

6.Using the 8" diameter fl exible vent pipe, apply high temperature 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 VENT

PIPE.

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 connec- tor, place the terminal over the air terminal connector making sure the inner pipe goes into the hole in the terminal. Secure screws

provided. FIGURE 24

7.Apply a heavy bead of weather- 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 vent pipe needs to be used

to reach the fi replace, couple them together as illustrated in Figure 25. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use noncombustible strapping to maintain a clearance to combustibles of 1".

1. Install the 5" fl exible
vent pipe to the fireplace.
Secure with 3 screws and flat
washers. Seal the joint and
screw holes using the high
temperature sealant W573-
