USING FLEXIBLE VENT COMPONENTS

Use only approved aluminum flexible liner kits marked:

“Wolf Steel Approved Venting” as identified by the stamp only on the 7” outer liner.

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

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).

Spacers are attached to the inner flex liner at predetermined

intervals to maintain a 1-1/4” air gap to the outer flex liner.

These spacers must not be removed.

HORIZONTAL AIR TERMINAL INSTALLATION

Note: Direct vent terminals shall not be recessed into a wall or siding.

1.Cut or frame a hole in an exterior wall with a minimum round or square opening of 111/2” W x 111/2” H if within 24” of the fi replace collars. If beyond 24” then a 91/2” W x 91/2” H opening is acceptable. Secure the fi restop spacer over the opening to the interior wall.

Secure the terminal to the terminal extension plate if required (see figure 18). The cover plate of the GD-222R terminal is 13”x13” and will cover the 11 1/2” x 11 1/2” opening but if the opening is made any larger - the terminal extension plate is required.

2.Stretch the 4” diameter aluminum fl exible liner 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 bead of the high temperature sealant.

3.Using the 7” diameter fl ex-

ible aluminum liner, slide over the CAULKING

outer combustion air sleeve of the

air terminal and secure with 3 #8 screws. Seal as before. 4. Insert the liners through the

fi restop maintaining the required clearance to combustibles. Se-FIGURE 17

weather tight by sealing with caulking (not supplied).

5.Apply a heavy bead of the high temperature sealant, (W573-0007 not provided), to the inside of the 4” liner ap- proximately 1” from the end. Slip the liner a minimum of 2” over the fi replace vent collar and secure with 3 #8 screws.

VERTICAL AIR TERMINAL INSTALLATION

1.Move the fi replace into position.

2.Fasten the roof support to the a 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. (Fig.a)

3.Stretch the inner aluminum

fl ex 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. (Fig.b)

4.Repeat using the outer aluminum

flex liner. (Fig.b)

5.Thread the air terminal connector / liner assembly down through the roof. The air terminal must be

located vertically and plumb. Attach the air terminal connector to the roof support, ensuring that the top of the air terminal is 16” above the highest point that it penetrates the roof. (Fig.c) If the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminal assembly as it is passed through the attic.

6. Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing over the

air terminal connector leaving a min. 3/4” of the air terminal connector showing above the top of the fl ashing. Slide the fl ashing 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 c the fl ashing with roofi ng material. (Fig.c)

7.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 with the three screws provided. (Fig.c)

8.Apply a heavy bead of weatherproof caulking 2 inches 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 connector and slide down to the caulking. Tighten to ensure that a weather-tight seal between the air terminal connector and the collar is achieved. (Fig.c)
